This book was released on 2011 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study presents a basic investigation on the influence of discharge on the variable sediment concentrations in the Andit Tid, Anjeni, and Maybar watersheds of northern Ethiopia. With valuable sediment concentration and stage measurements recorded by the Soil Conservation Research Programme at monitoring sites starting in the 1980's, it is possible to gain knowledge about the important processes that affect changing sediment concentrations. For the years of observation, sediment yield estimates were 5.4 t[MIDDLE DOT]ha-1y-1, 22.5 t[MIDDLE DOT]ha-1y-1, and 8.8 t[MIDDLE DOT]ha-1y-1 for Andit Tid, Anjeni, and Maybar respectively. Although catchments tend to exhibit positive correlation between runoff and sediment concentration, albeit with a degree of scatter, these catchments exhibit a peculiar scatter of observations with high concentrations for low flows and low concentrations for high flows. Due to this behavior, a sediment rating curve for all observations was unsatisfactory and subsequently, using several cumulative precipitation divisions to group related observations, non-linear regression showed a weak correlation for the Andit Tid basin, for most of the Anjeni basin and during the early portion of the rainy season in the Maybar basin. Stratification of points into cumulative precipitation ranges served to bring some order to the scatter plots of sediment concentration versus discharge to demonstrate that higher concentrations are observed during the beginning of the rainy season and lower concentrations are observed towards the end of the rainy season. Still, the exhaustion of available soil for transport may prove to have an important role in limiting the ability of discharge to account for the variability of sediment concentration throughout the season.

Download or read book Landscapes and Landforms of Ethiopia written by Paolo Billi and published by Springer. This book was released on 2015-03-23 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a succinct but comprehensive presentation of key geomorphological locations and topics including information about geomorphological heritage and maps to visit the most important sites. Apart from often being remarkably scenic, landscapes reveal stories that often can be traced back in time tens of million years and include unique events. This is particularly true for Ethiopia where spectacular examples of different landforms are present. Its geomorphology varies from highlands, marked by high volcanoes and incised by deep river gorges, to the rift valley lakes endorheic systems and the below sea level lowlands with characteristic landscapes which are unique in the world. Landscapes and Landforms of Ethiopia highlights all these topics including essential information about geology and tectonic framework, past and present climate, hydrology, geographical regions and long-term geomorphological history. It is a highly informative book, providing insight for readers with an interest in geography and geomorphology.

Download or read book The Nile River Basin written by Seleshi Bekele Awulachew and published by Routledge. This book was released on 2013-03-05 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nile provides freshwater not only for domestic and industrial use, but also for irrigated agriculture, hydropower dams and the vast fisheries resource of the lakes of Central Africa. The Nile River Basin covers the whole Nile Basin and is based on the results of three major research projects supported by the Challenge Program on Water and Food (CPWF). It provides unique and up-to-date insights on agriculture, water resources, governance, poverty, productivity, upstream-downstream linkages, innovations, future plans and their implications. Specifically, the book elaborates the history and the major current and future challenges and opportunities of the Nile river basin. It analyzes the basin characteristics using statistical data and modern tools such as remote sensing and geographic information systems. Population distribution, poverty and vulnerability linked to production system and water access are assessed at the international basin scale, and the hydrology of the region is also analysed. This text provides in-depth scientific model adaptation results for hydrology, sediments, benefit sharing, and payment for environmental services based on detailed scientific and experimental work of the Blue Nile Basin. Production systems as they relate to crops, livestock, fisheries and wetlands are analyzed for the whole Blue and White Nile basin including their constraints. Policy, institutional and technological interventions that increase productivity of agriculture and use of water are also assessed. Water demand modeling, scenario analysis, and tradeoffs that inform future plans and opportunities are included to provide a unique, comprehensive coverage of the subject.
Download or read book Nile River Basin written by Assefa Melesse and published by Springer. This book was released on 2014-02-28 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a comprehensive overview of the hydrology of the Nile River, especially the ecohydrological degradation and challenges the basin is facing, the impact of climate change on water availability and the transboundary water management issues. The book includes analysis and approaches that will help provide different insights into the hydrology of this complex basin, which covers 11 countries and is home to over 300 million people. The need for water-sharing agreements that reflect the current situations of riparian countries and are based on equitable water- sharing principles is stressed in many chapters. This book explores water resource availability and quality and their trends in the basin, soil erosion and watershed degradation at different scales, water and health, land use and climate change impact, transboundary issues and water management, dams, reservoirs and lakes. The link between watershed and river water quantity and quality is discussed pointing out the importance of watershed protection for better water resource management, water accessibility, institutional set-up and policy, water demand and management. The book also presents the water sharing sticking points in relation to historical treaties and the emerging water demands of the upstream riparian countries. The need for collaboration and identification of common ground to resolve the transboundary water management issues and secure a win-win is also indicated. "
Download or read book Social and Ecological System Dynamics written by Krystyna Stave and published by Springer. This book was released on 2017-04-06 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a social—ecological system description and feedback analysis of the Lake Tana Basin, the headwater catchment of the Upper Blue Nile River. This basin is an important local, national, and international resource, and concern about its sustainable development is growing at many levels. Lake Tana Basin outflows of water, sediments, nutrients, and contaminants affect water that flows downstream in the Blue Nile across international boundaries into the Nile River; the lake and surrounding land have recently been proposed as a UNESCO Biosphere Reserve; the basin has been designated as a key national economic growth corridor in the Ethiopian Growth and Transformation Plan. In spite of the Lake Tana Basin’s importance, there is no comprehensive, integrated, system-wide description of its characteristics and dynamics that can serve as a basis for its sustainable development. This book presents both the social and ecological characteristics of the region and an integrated, system-wide perspective of the feedback links that shape social and ecological change in the basin. Finally, it summarizes key research needs for sustainable development.
