Download or read book Application of Water Evaluation and Allocation Planning WEAP Model to Assess Future Water Demands and Water Balance of the Caledon River Basin written by Abebe Seyoum Ayele and published by . This book was released on 2016 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Caledon catchment is one of the 19 catchments in South Africa and three catchments in Lesotho. It covers part of the south eastern Free State in South Africa and northern part of Lesotho. It is important to evaluate the water resources of the catchment to satisfy the projected water demands and in order to plan for the future and make wise decisions. The objective of this study was to apply the Water Evaluation and Planning System version 21 (WEAP21) as a Decision Support System (DSS) tool for the allocation and development of water resources in the Caledon catchment. The model was structured according to three scenarios with a current account (2014) and reference period (2015-2050) to predict their possible impacts on the water balance and allocation of the region due to varied water demands. The scenarios are as follows: scenario 1: increase in population growth rates; scenario 2: irrigation activities in Lesotho; and scenario 3: implementation of environmental flow requirement (EFR) on Caledon River at a site referred to as C6. The first two scenarios are consumptive scenarios whereas the third is a non-consumptive scenario. Scenario analysis answers “what if” questions for the future. Population growth has contributed to water scarcity problem in many parts of the world. In this context, scenario 1 deals with the impact of an increase in population growth on the water balance after 2020 by analysing the unmet demands that will be incurred over the reference period. Scenario 2 also analyses the unmet demands if irrigation activities in Lesotho are increased after 2020. Scenario 3 evaluates the impact of the implementation of an EFR site at C6 – which is situated downstream of all demand sites of the catchment – on upstream demands. Projected water demands and unmet demands were evaluated for four water use sectors, namely, domestic, industry, irrigation and livestock. The catchment comprised of 46 demand sites which were categorised into four use sectors: 20 domestic demand sites, 11 irrigation sites, 10 livestock sites and five industrial sites in both rural and urban areas. The modelling results show that high population growth increases the water shortage to all water use sectors in the catchment. Under a high population growth scenario, the unmet demand occurred between May and October. However, under reference, EFR and irrigation scenarios, the unmet demand occurred only from June to September. The annual unmet demand will increase substantially after 2020 in a high population growth scenario and when the population growth rates are altered. The demand from the irrigation sector is covered or no unmet demands are registered in all years. This is because active irrigation activities happen from December to May when enough water is available from the rivers. The years 2025 and 2050 were chosen to evaluate the water balance situations in terms of supply and demand in the middle and at the end of the reference period under two water use scenarios (high population growth and irrigation added). The result shows that the river flows meet the projected demand in 2025. However, most rivers, including the main river (Caledon River), will not be able to meet the required demands in 2050.

Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the extraordinary range of areas to which geographical analysis and spatial modelling can bring lessons and insights. It shows how these techniques have been used to address ‘real world’ issues that are of concern to international organisations, public agencies and businesses, as illustrated by actual funded projects that geographers have developed collaboratively with end-users. Applied Spatial Modelling and Planning shows how much geographical research is policy relevant to a wide variety of agencies through the use of GIS and spatial modelling in applied geography. The book’s chapters contain a cross-section of innovative applications and approaches to problem solving within five major domains of the dynamics of economic space, housing and settlements, population movements and population ageing, health care, and the environment. Using a number of case studies on the use of GIS and spatial modelling, this book demonstrates the fact that much of what is done by quantitative geographers is not only relevant within academia, but also has use in policy work. This book will appeal to an international audience interested in cutting-edge spatial modelling to better understand the processes involved in solving real problems.

Download or read book Decision Support Tool for Water Management and Environmental Flows written by Jenny Ta and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream flow drives many physical and ecological processes in rivers that support freshwater ecosystems. Human activities like dam operations, water diversions, and flood control infrastructure together have fundamentally altered many streams. Water scarcity from increasing water demands and prolonged droughts has further stressed freshwater ecosystems, which in turn is prompting the development of new methods and tools for establishing environmental flows. This study developed a linear programming model for exploring the effects of water management alternatives on environmental flows in river systems that have minimal or no regulation from dam operations, but still have altered flow regimes due to surface water diversions. The model was applied to a case study on Mill Creek, a tributary of the Sacramento River in northern California's Tehama County, whose altered flow regime affects fall and spring fish migration to upstream spawning habitat. Test cases were used to examine how water management alternatives can improve environmental flow allocations while striving to meet agricultural water supply demands. These test cases included: 1) fish passage flows for California Central Valley Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss); 2) a 2.55 cms minimum instream flow (MIF); and 3) a sustainability boundary approach (SBA) with a flow target of 80% of natural flow. The model quantifies the effect of water management alternatives such as conjunctive use, water rights transfers, and water exchange agreements on instream environmental flow conditions. The model identified the last two weeks of October as a consistent period of shortage for fall fish passage flows during all water year types from critically dry to wet water years. Shortages to fish passage flows could be eliminated through the combined use of a water exchange agreement and conjunctive use wells. The MIF and SBA environmental flow cases both required acquisition of the largest water right holder in the system to decrease environmental shortages by over 80%. This modeling approach can be applied to other river systems as a decision-support tool for conservation organizations and government agencies to make more informed decisions regarding management of scarce water resources to maximize ecological function while minimizing impact on human uses of water.
