Available in PDF, EPUB and Kindle. Book excerpt: This book provides scientific evidence to underline the notion that forests offer the most reliable water catchments in the natural environment. The unique Australian ecosystem provides valuable information on the water yields and hydro-ecology of forests. Insights can be transferred to other climate zones and conditions. In this second edition, the author puts a particular focus on the most prominent challenges of our time, in relation to water management. Ground salinity, climate change, and droughts have all been newly added to this updated edition. One of the most important concepts is highlighting the accumulated contribution of smaller catchments and minor streams. Finally, readers will also get information on the economic dimension of water management. With its incisive, disciplined, and quantitative (and occasionally humorous) approach, this book helps scientists, students, and regulators to understand water-driven conflicts and offers guidance on management.

Download or read book Flood Routing in Ungauged Catchments Using Muskingum Methods written by Mesfin H. Tewolde and published by Universal-Publishers. This book was released on 2008-03-27 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: River stage or flow rates are required for the design and evaluation of hydraulic structures. Most river reaches are ungauged and a methodology is needed to estimate the stages, or rates of flow, at specific locations in streams where no measurements are available. Flood routing techniques are utilised to estimate the stages, or rates of flow, in order to predict flood wave propagation along river reaches. Models can be developed for gauged catchments and their parameters related to physical characteristics such as slope, reach width, reach length so that the approach can be applied to ungauged catchments in the region. The objective of this study is to assess Muskingum-based methods for flow routing in ungauged river reaches, both with and without lateral inflows. Using observed data, the model parameters were calibrated to assess performance of the Muskingum flood routing procedures and the Muskingum-Cunge method was then assessed using catchment derived parameters for use in ungauged river reaches. The Muskingum parameters were derived from empirically estimated variables and variables estimated from assumed river cross-sections within the selected river reaches used. Three sub-catchments in the Thukela catchment in KwaZulu-Natal, South Africa were selected for analyses, with river lengths of 4, 21 and 54 km. The slopes of the river reaches and reach lengths were derived from a digital elevation model. Manning roughness coefficients were estimated from field observations. Flow variables such as velocity, hydraulic radius, wetted perimeters, flow depth and top flow width were determined from empirical equations and cross-sections of the selected rivers. Lateral inflows to long river reaches were estimated from the Saint-Venant equation. Observed events were extracted for each sub-catchment to assess the Muskingum-Cunge parameter estimation method and Three-parameter Muskingum method. The extracted events were further analysed using empirically estimated flow variables. The performances of the methods were evaluated by comparing both graphically and statistically the simulated and observed hydrographs. Sensitivity analyses were undertaken using three selected events and a 50% variation in selected input variables was used to identify sensitive variables. The performance of the calibrated Muskingum-Cunge flood routing method using observed hydrographs displayed acceptable results. Therefore, the Muskingum-Cunge flood routing method was applied in ungauged catchments, with variables estimated empirically. The results obtained shows that the computed outflow hydrographs generated using the Muskingum-Cunge method, with the empirically estimated variables and variables estimated from cross-sections of the selected rivers resulted in reasonably accurate computed outflow hydrographs with respect to peak discharge, timing of peak flow and volume. From this study, it is concluded that the Muskingum-Cunge method can be applied to route floods in ungauged catchments in the Thukela catchment and it is postulated that the method can be used to route floods in other ungauged rivers in South Africa.

Download or read book Biogeochemical Monitoring in Small Catchments written by Jirí Cerný and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue of Water, Air and Soil Pollution offers original contributions from BIOGEOMON, an international symposium on ecosystem behavior and the evaluation of integrated monitoring of small catchments, held in Prague, Czech Republic, in September 1993. The meeting attracted nearly 200 scientists from 27 countries on five continents. BIOGEOMON was a loose continuation of another international meeting, GEOMON, which was held in Prague in 1987. Both sym posia provided a forum for the discussion of ideas on environmental problems in western and eastern Europe, with important contributions from the American continent. With the dramatic collapse of the iron curtain, it was our hope that more so than GEOMON, BIOGEOMON would provide opportunities for the free exchange of ideas, fostering the development of research collaborations between its participants. With international openness comes the increasing realization that every indus trialized nation has its own legacy of environmental degradation. Anthropogenic impacts differ in severity and scale; air and water transport of pollutants transform local impacts into regional and global ones, ignoring political boundaries and eco nomic differences. Environmental consequences of anthropogenic activities often are detectable at the ecosystem level. Thus, the challenge of ecosystem science, and to the individuals who practice it, is to develop a comprehensive understanding of ecosystem function in the past and at present, and to apply such understanding toward minimizing future insults to the local, regional, and global environment.

Download or read book Biogeochemistry of Forested Catchments in a Changing Environment written by Egbert Matzner and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest ecosystems represent a major type ofland use in Germanyand in Europe. They provide a number of functions, or ecosystem services, beneficial to humans, namely biomass production, regulation of the water- and energy cyde, C and N sequestration, erosion control, recreation, and they act as habitat for numerous species. The stability of forest ecosystems in Europe as influenced by the deposition of air pollutants has been a matter of debate for more than 20 years. Besides atmospheric deposition, other environmental conditions affecting forest ecosystems, such as temperature, CO content of the atmosphere 2 and precipitation, have significantly changed in the past and continue to change in the future. Quantifying and predicting the effects of these changes on ecosys tem functioning are achallenge to ecosystem research and also a requirement to establish sustainable use of forest ecosystems in the future. This book summarizes results of long-term, interdisciplinary ecosystem research conducted in two forested catchments and coordinated at the Bayreuth Institute of Terrestrial Ecosystem Research (BITÖK), University of Bayreuth, Germany. It does not aim to summarize all the research of BITÖ K in the past decade, which would go far beyond the studies in these two catch ments. Instead, we concentrate here on the long-term developments in the biogeochemistry of carbon and mineral elements and on the water cyde, at both the plot and the catchment scale.

Download or read book Rainfall runoff Modelling in Gauged and Ungauged Catchments written by Thorsten Wagener and published by World Scientific. This book was released on 2004 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important monograph is based on the results of a study on the identification of conceptual lumped rainfall-runoff models for gauged and ungauged catchments. The task of model identification remains difficult despite decades of research. A detailed problem analysis and an extensive review form the basis for the development of a Matlab? modelling toolkit consisting of two components: a Rainfall-Runoff Modelling Toolbox (RRMT) and a Monte Carlo Analysis Toolbox (MCAT). These are subsequently applied to study the tasks of model identification and evaluation. A novel dynamic identifiability approach has been developed for the gauged catchment case. The theory underlying the application of rainfall-runoff models for predictions in ungauged catchments is studied, problems are highlighted and promising ways to move forward are investigated. Modelling frameworks for both gauged and ungauged cases are developed. This book presents the first extensive treatment of rainfall-runoff model identification in gauged and ungauged catchments.

Download or read book Farming Action Catchment Reaction written by J Williams and published by CSIRO PUBLISHING. This book was released on 1998-01-01 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dryland farming is a major export earner for many temperate-zone countries, yet it continues to degrade a country's natural resources. Effects are not restricted to the land - changes in water quality can reduce the potential uses of water and bring about catastrophic changes in both freshwater and coastal ecosystems. Farming Action: Catchment Reaction provides a comprehensive technical overview of the relationships between dryland farming systems and catchment land and water quality in Australia, and integrates it in a whole system framework. It deals with the issues in terms of people, pointers, processes and prediction as it discusses social aspects of developing and implementing research to improve dryland farming systems in catchment management programs, indicators of catchment health, and the processes which determine the impact of the farming action on the catchment response. It concludes by considering the adequacy of our ability to use this process knowledge in models to predict the effect of dryland farming on catchment condition.
