Download or read book Evaluation of Climate Change Impact on Stream Flow written by Andualem Shimeles and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: To assess how stream flow in Gilgel Abbay River Basin will be affected by climate change, the HadCM3 model, developed at the Hadley Centre in the United Kingdom, was used to generate medium-high and medium-low emission scenarios in this study. The statistical downscaling model was used to generate future possible local meteorological variables in the study area. The down-scaled data were then used as input to the Soil and Water Assessment Tool hydrological model to simulate the corresponding future stream flow regime in Gilgel Abbay River Basin. Three benchmark periods simulated were 2011-2040 (2020s), 2041-2070 (2050s), and 2071-2099 (2080s). The time series generated by HadCM3 and statistical downscaling method indicate a significant increasing trend in both maximum and minimum temperature values, and a decreasing trend in precipitation. The hydrologic impact analysis made with the downscaled temperature and precipitation time series as input to the SWAT model suggested an overall decreasing trend in annual and monthly stream flow in the study area, in three benchmark periods in the future. This should be considered by policymakers of water resources planning and management.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 21st century, changes in induced climate can significantly affect the water resources system in the watershed. Understanding climate change disrupts hydrological processes can facilitate sustainable water resource strategies to resilient impacts of global warming. The hydrological response of watersheds will be accelerated by climate change, altering the rainfall, magnitude & timing of runoff, and sediment yield. The study investigates climate change aspects on the hydrological responses using Soil and Water Assessment Tool (SWAT) model interfaced with Geographical Information System (GIS) of Genale Basin, Ethiopia. The calibrated SWAT was applied to simulate the impact of climate, and the SUFI-II algorithm was used for parameter optimization & finalization. The change of climate scenarios was built using the outcomes bias-corrected CORDEX RCM daily precipitation, min/max temperature for Ethiopia under RCP 4.5 and RCP 8.5. The average monthly change of streamflow from ,àí16.47% to 6.58% and¬†,àí¬†3.6% to 8.27% under RCP4.5 and RCP8.5, respectively (2022,Äì2080). The monthly average sediment yield change was ,àí21.8% to 6.2% and¬†,àí¬†5.6% to 4.66% for the RCP4.5 and RCP8.5 scenarios, respectively, over 2022,Äì2080. It implies that the climate change-induced impacts on sediment yield are more significant than streamflow and suggest substantial adaptive management in watershed systems.

Download or read book Climate Change Impacts on Water Resources written by Ramakar Jha and published by Springer Nature. This book was released on 2021-03-27 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides insights and a capacity to understand the climate change phenomenon, its impact on water resources, and possible remedial measures. The impact of climate change on water resources is a global issue and cause for concern. Water resources in many countries are extremely stressed, and climate change along with burgeoning populations, the rise in living standards, and increasing demand on resources are factors which serve to exacerbate this stress. The chapters provide information on tools that will be useful to mitigate the adverse consequences of natural disasters. Fundamental to addressing these issues is hydrological modelling which is discussed in this book and ways to combat climate change as an important aspect of water resource management.

Download or read book Climate Change and Water Resources Management written by Levi D. Brekke and published by DIANE Publishing. This book was released on 2009-11 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many challenges, including climate change, face the Nation¿s water managers. The Intergovernmental Panel on Climate Change (IPCC) has provided estimates of how climate may change, but more understanding of the processes driving the changes, the sequences of the changes, and the manifestation of these global changes at different scales could be beneficial. Since the changes will likely affect fundamental drivers of the hydrological cycle, climate change may have a large impact on water resources and water resources managers. The purpose of this interagency report is to explore strategies to improve water management by tracking, anticipating, and responding to climate change. Charts and tables.

Download or read book Impact of Global Climate Change on Extreme Streamflow written by Sabin Shrestha (Civil engineer) and published by . This book was released on 2017 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a widespread concern that climate change will lead to an increased frequency and intensity of extreme weather events in the 21st century. It is essential, from a watershed management point of view to understand how these alterations in the hydrologic regime would affect the existing water resources. This research, therefore, provides an overview of the hydrologic impacts on the Great Miami River Watershed in Ohio, USA due to projected climatic changes on both low flows and high flows. An extensively used hydrological model, the Soil and Water Assessment Tool (SWAT) was to evaluate the hydrological impacts of climate change. The multi-site model calibration and validation were performed using the SUFI-2 algorithm within SWAT-CUP. The model was calibrated (2005 - 2014) and validated (1995 - 2004) for monthly stream flows at the outlet resulting in Nash - Sutcliffe Coefficients of 0.86 and 0.83, respectively. An ensemble of ten downscaled and bias-corrected climate models from Fifth Phase Coupled Model Intercomparison Project (CMIP5) under two Representative Concentration Pathways(RCPs) 4.5 and 8.5 were used to generate a probable set of climate data (precipitation and temperature). The climate data were then fed into the SWAT model and hydrological changes in the stream in terms of daily discharge were produced for three time-frames: (2016 - 2043) as 2035s, (2044 - 2071) as 2055s, and (2072 - 99) as 2085s and compared against the baseline period (1988 - 2015). The findings from this research showed that low flows using both hydrological and biological indices would increase more than 100% in 2035s but eventually decrease slightly in the later part of the century (2085s). However, the Max Planck Institute Earth System Model (MPI-ESM-LR) used in this study predicted that the biological indices iv under RCP 8.5 would increase slightly at the beginning but decrease considerably in the middle and later part of the century. Analysis showed that the variability of the average 7-day low flows in each year would increase considerably for both emission scenarios. Furthermore, 75th percentile exceedance frequency of monthly low flows was found higher in September, October, and November during the study period. As for high flow analysis, the hydrological index for high flows (7Q10) from an ensemble of 10 climate models predicted to decrease consistently in future. When the results from the two RCPs are compared, high flows would decrease maximum by 22% in 2055s under RCP 8.5 and 21% in 2085s under RCP 4.5. However, the MIROC5 model in RCP 4.5 showed 1.2% increase in 7Q10 high flows during 2035s. The frequency of the 75th percentile non-exceedance flows was also projected to increase in the future. Under the RCP 4.5, the frequency becomes higher in 2055s whereas under the RCP 8.5 most frequent 75th percentile flow would occur in 2085s. Meanwhile, on a monthly scale, the peak would increase more on every month except January and December than that of historical records. The variability of peak discharge was also expected to increase in every other month in both scenarios. The peak would increase considerably especially in August, September, and October when compared to historical months, indicating relatively wetter months in the future years. Finally, this study has demonstrated the effects of changing climates projected by the climate models on extreme flow condition in the large agricultural watershed. The next step of the research will focus on further bias correction on simulated climate data and analysis for future.

Download or read book Colorado River Basin Water Management written by National Research Council and published by National Academies Press. This book was released on 2007-06-30 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies of past climate and streamflow conditions have broadened understanding of long-term water availability in the Colorado River, revealing many periods when streamflow was lower than at any time in the past 100 years of recorded flows. That information, along with two important trends-a rapid increase in urban populations in the West and significant climate warming in the region-will require that water managers prepare for possible reductions in water supplies that cannot be fully averted through traditional means. Colorado River Basin Water Management assesses existing scientific information, including temperature and streamflow records, tree-ring based reconstructions, and climate model projections, and how it relates to Colorado River water supplies and demands, water management, and drought preparedness. The book concludes that successful adjustments to new conditions will entail strong and sustained cooperation among the seven Colorado River basin states and recommends conducting a comprehensive basinwide study of urban water practices that can be used to help improve planning for future droughts and water shortages.

This book was released on 2014-01-18 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with an overview of data and concepts developed in the EU-project HABIT-CHANGE, this book addresses the need for sharing knowledge and experience in the field of biodiversity conservation and climate change. There is an urgent need to build capacity in protected areas to monitor, assess, manage and report the effects of climate change and their interaction with other pressures. The contributors identify barriers to the adaptation of conservation management, such as the mismatch between planning reality and the decision context at site level. Short and vivid descriptions of case studies, drawn from investigation areas all over Central and Eastern Europe, illustrate both the local impacts of climate change and their consequences for future management. These focus on ecosystems most vulnerable to changes in climatic conditions, including alpine areas, wetlands, forests, lowland grasslands and coastal areas. The case studies demonstrate the application of adaptation strategies in protected areas like National Parks, Biosphere Reserves and Natural Parks, and reflect the potential benefits as well as existing obstacles. A general section provides the necessary background information on climate trends and their effects on abiotic and biotic components. Often, the parties to policy change and conservation management, including managers, land users and stakeholders, lack both expertise and incentives to undertake adaptation activities. The authors recognise that achieving the needed changes in behavior – habit – is as much a social learning process as a matter of science-based procedure. They describe the implementation of modeling, impact assessment and monitoring of climate conditions, and show how the results can support efforts to increase stakeholder involvement in local adaptation strategies. The book concludes by pointing out the need for more work to communicate the cross-sectoral nature of biodiversity protection, the value of well-informed planning in the long-term process of adaptation, the definition of acceptable change, and the motivational value of exchanging experience and examples of good practice.

This book was released on 2008 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Technical Paper addresses the issue of freshwater. Sealevel rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species. -- page vii.

Download or read book Climate Change Adaptation in Eastern Europe written by Walter Leal Filho and published by Springer. This book was released on 2018-12-15 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on managing risks and building resilience to climate change, showcasing experiences from research, field projects and best practices to foster climate change adaptation in Eastern Europe that can be implemented elsewhere. Climate change affects countries in Eastern Europe, i.e. the Western Balkans and Southeast Europe in a variety of ways. Apart from severe floods, there are reports of decreasing water reserves in the southern regions, and of gradual changes in biodiversity and agricultural production. In the South Caucasus area, for instance, climate change models project a decline in precipitation and suggest that it will continue to become drier this century. Many Eastern European countries, especially the non-EU ones, have weak national climate policies, and transboundary collaborations, as well as limited public engagement in matters related to climate change. As a result, climate change poses a serious threat to their economic stability and development and to the sustainable development of the region. The above state of affairs illustrates the need for a better understanding of how climate change influences Eastern Europe, and for the identification of processes, methods and tools that may help the countries and the communities in the region to adapt. There is also a perceived need to showcase successful examples of how to cope with the social, economic and political problems posed by floods/droughts in the region, especially ways of increasing the resilience of agriculture systems and of communities. Addressing this need, the book presents papers written by scholars, social practitioners and members of government agencies involved in research and/or climate change projects in Eastern Europe.

Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Download or read book The Impacts of Climate Change on Regional Water Resources and Agriculture in Africa written by Kenneth M. Strzepek and published by World Bank Publications. This book was released on 2007 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes the methods and findings of the hydrological assessment component of the project studying likely impacts of climate change on water resources and agriculture in Africa. The first phase of the study used a version of a conceptual rainfall-runoff model called WatBal (Water Balance) applied to gridded data to simulate changes in soil moisture and runoff across the whole continent of Africa rather than to any particular catchment or water resource system. The model inputs were the climate variables of the 1961-90 climatology and physiological parameters (such as soil properties and land use) derived from global datasets for each of the 0.5 degree latitude/longitude cells across the continent. The primary model output comprised a time series (monthly time step) of simulated runoff for all the grid cells for each of the districts in the countries of interest. The second phase of the study extended the hydrology analyses to update the above hydroclimatic series to the year 2000 using updated input data. To ascertain the possible impacts of climate change within the districts being investigated this study used synthetic or GCM-based climate change scenarios as input to the WatBal model. The WatBal model was used to determine the impact of these different scenarios on runoff and actual evaporation and hence flow in the districts under study. The generated hydroclimatic series and scenario analyses were used as inputs into various Ricardian regressions in other analyses measuring likely impacts of climate change on the agricultural economies of Africa.
