Book excerpt: Climate change brings about several new hydrological changes including changes in intensity and frequency of extreme events such as drought and extreme precipitation. For a more accurate understanding of the impact of these extreme events on water resources, work is being done to move towards methods capable of accounting for nonstationarity. In this work, I examine how the presence of spatial nonstationarity and temporal nonstationarity can affect water resource management in two contexts. First, I consider drought in California linked to warming winter temperatures. The spatial nonstationarity present in California temperature records complicate attempts to create gridded datasets from station observations, and ability of the interpolation method to account for spatial nonstationarity greatly impacts the final products. I examine five gridded datasets to find substantial differences between winter temperature trend magnitudes and spatial patterns largely due to the interpolation method selected as well as to differences in station lists and bias correction methods. The differences in temperature also strongly impact modeled changes in Snow Water Equivalent (SWE) over the last century, which are a vital component of water resources in California. Second, I examine extreme precipitation using Monte Carlo simulations representing events typical in the US to determine the bias and variance in error associated with using a temporally stationary versus temporally nonstationary model. In comparing the performance between a stationary and nonstationary version of the generalized extreme value distribution, I find the classic bias-variance tradeoff in modeling limits the usefulness of using a nonstationary distribution, which should be applied when record length is long, the coefficient of variation of the data is low, and the behavior of temporal nonstationarity is high (large increases in the mean and standard deviation of the data with time). This result complicates the reality of transferring from a stationary method of analysis to a nonstationary, revealing that for many stations in the US, record lengths are too short (fifty years and under) for the nonstationary application to be definitively useful.
Download or read book Global Change and Extreme Hydrology written by National Research Council and published by National Academies Press. This book was released on 2011-12-17 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate theory dictates that core elements of the climate system, including precipitation, evapotranspiration, and reservoirs of atmospheric and soil moisture, should change as the climate warms, both in their means and extremes. A major challenge that faces the climate and hydrologic science communities is understanding the nature of these ongoing changes in climate and hydrology and the apparent anomalies that exist in reconciling their extreme manifestations. The National Research Council (NRC) Committee on Hydrologic Science (COHS) held a workshop on January 5-6, 2010, that examined how climate warming translates into hydrologic extremes like floods and droughts. The workshop brought together three groups of experts. The first two groups consisted of atmospheric scientists and hydrologists focused on the scientific underpinnings and empirical evidence linking climate variability to hydrologic extremes. The third group consisted of water managers and decision-makers charged with the design and operation of water systems that in the future must be made resilient in light of a changing climate and an environment of hydrologic extremes. Global Change and Extreme Hydrology summarizes the proceedings of this workshop. This report presents an overview of the current state of the science in terms of climate change and extreme hydrologic events. It examines the "conventional wisdom" that climate change will "accelerate" the hydrologic cycle, fuel more evaporation, and generate more precipitation, based on an increased capacity of a warmer atmosphere to hold more water vapor. The report also includes descriptions of the changes in frequency and severity of extremes, the ability (or inability) to model these changes, and the problem of communicating the best science to water resources practitioners in useful forums.

Download or read book Managing Protected Areas in Central and Eastern Europe Under Climate Change written by Sven Rannow and published by Springer Science & Business Media. 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.

Download or read book Statistical Analysis and Stochastic Modelling of Hydrological Extremes written by Hossein Tabari and published by MDPI. This book was released on 2019-10-28 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrological extremes have become a major concern because of their devastating consequences and their increased risk as a result of climate change and the growing concentration of people and infrastructure in high-risk zones. The analysis of hydrological extremes is challenging due to their rarity and small sample size, and the interconnections between different types of extremes and becomes further complicated by the untrustworthy representation of meso-scale processes involved in extreme events by coarse spatial and temporal scale models as well as biased or missing observations due to technical difficulties during extreme conditions. The complexity of analyzing hydrological extremes calls for robust statistical methods for the treatment of such events. This Special Issue is motivated by the need to apply and develop innovative stochastic and statistical approaches to analyze hydrological extremes under current and future climate conditions. The papers of this Special Issue focus on six topics associated with hydrological extremes: Historical changes in hydrological extremes; Projected changes in hydrological extremes; Downscaling of hydrological extremes; Early warning and forecasting systems for drought and flood; Interconnections of hydrological extremes; Applicability of satellite data for hydrological studies.

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 Attribution of Extreme Weather Events in the Context of Climate Change written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-07-28 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts. Even with evidence of these broad trends, scientists cautioned in the past that individual weather events couldn't be attributed to climate change. Now, with advances in understanding the climate science behind extreme events and the science of extreme event attribution, such blanket statements may not be accurate. The relatively young science of extreme event attribution seeks to tease out the influence of human-cause climate change from other factors, such as natural sources of variability like El Niño, as contributors to individual extreme events. Event attribution can answer questions about how much climate change influenced the probability or intensity of a specific type of weather event. As event attribution capabilities improve, they could help inform choices about assessing and managing risk, and in guiding climate adaptation strategies. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.
