Land Degradation in the Dinder and Rahad Basins: Interactions Between Hydrology, Morphology and Ecohydrology in the Dinder National Park, Sudan

The spatial and temporal variability of the hydro-climate as well as land use and land cover (LULC) changes are among the most challenging problems facing water resources management. Understanding the interaction between climate variability, land use and land cover changes and their links to hydrology, river morphology and ecohydrology in the...

Climate change and development impacts on groundwater resources in the Nile delta aquifer, Egypt

Climate change (CC), as predicted by several global climate models, is very likely to have severe impacts in the future, on top of all other global changes. These impacts may have significant influence on natural resources especially surface and groundwater. This influence is particularly problematic for the Mediterranean coastal areas, and...

Optimizing the operation of a multiple reservoir system in the eastern nile basin considering water and sediment fluxes

The Eastern Nile (EN) riparian countries Egypt, Ethiopia and Sudan are currently<br/>developing several reservoir projects to contribute to the needs for energy and food<br/>production in the region. The Nile Basin, particularly the Eastern Nile Sub-basin, is<br/>considered one of the international river systems with potential conflicts between...

Improved hydrological understanding of a semi-arid subtropical transboundary basin using multiple techniques – the Incomati River Basin

This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool was deployed to describe the streamflow regime...

Quantitative assessment of groundwater and Surface water interactions in the Hailiutu river basin, Erdos plateau, China

This study presents a multi-disciplinary approach for investigating the interactions between groundwater and surface water in the semi-arid Hailiutu catchment in the Erdos Plateau, Northwest China. The study consists of statistical detection of river flow regime shifts at the basin level; multiple in-situ measurements for quantifying groundwater...

Soil hydrological impacts and climatic controls of land use and land cover changes in the Upper Nile (Abay) Basin

Hydrological drought forecasting in Africa at different spatial and temporal scales

Understanding Catchment Processes and Hydrological Modelling in the Abay/Upper Blue Nile Basin, Ethiopia

The water resources in the Abay/Upper Blue Nile basin are the source of life for the several hundred million people living in the basin and further downstream. It provides more than 60% of the total Nile water. Intensive farming in unfavourable soils and slopes, overgrazing and soil erosion is among the major problems in the basin. Land...

Surface and Subsurface Runoff Generation Processes in a Poorly Gauged Tropical Coastal Catchment

Water Tower of the Yellow River in a Changing Climate: Toward an integrated assessment

Climate change due to increasing greenhouse gas emissions is likely to alter the hydrological cycle resulting in large impacts on water resources worldwide. Mountain regions are important sources of freshwater for the entire globe, but their role in global water resources could be significantly altered by climate change. Mountains are expected...

Fate and Transport of Nutrients in Groundwater and Surface Water in an Urban Slum Catchment Kampala, Uganda

This study investigates the generation, transport and fate of sanitation-related nutrients in groundwater and surface water in an urban slum area in sub-Saharan Africa. In excess, nutrients can cause eutrophication of downstream water bodies. The study argues that nitrogen-containing rains and domestic wastewater from slum areas were important...

Space-time variation of hydrological processes and water resources in Rwanda: Focus on the Migina catchment

This book presents the hydrological research carried out in the Migina catchment (260 km2), Southern Rwanda. The main objective of the research is to explore the hydrological trends and climate linkages for catchments in Rwanda (26,338 km2), and to contribute to the understanding of dominant hydrological process interactions. Different hydro...

Water Resources Strategies to increase Food Production in the Semi-Arid Tropics: With particular emphases on the potential of alluvial groundwater

Transport of multiple Escherichia coli strains in saturated porous media

The deviation of bacteria transport and deposition patterns on grains in porous media from theory has resulted in the inability to accurately predict transport distances in aquifers, with consequences of polluting drinking water sources (springs, boreholes and wells). Due to the importance of Escherichia coli (E. coli) as an indicator of faecal...

Understanding hydrological variability for improved water management in the Semi-Arid Karkheh basin, Iran

This study provides a hydrology based assessment of (surface) water resources and its continuum of variability and change at different spatio-temporal scales in the semi-arid Karkheh Basin, Iran, where water is scarce, competition among users is high and massive water resources development is under way. The study reveals that the ongoing...

Water productivity in rainfed agriculture; redrawing the rainbow of water to achieve food security in rainfed smallholder systems

The challenge of water scarcity as a result of insufficient seasonal rainfall and dry spell occurrences during cropping seasons is compounded by inefficient agricultural practices by smallholder farmers where insignificant soil and water conservation efforts are applied. The hypothesis of this research is that many of the past research efforts...

Understanding Hydrological Processes in an Ungauged Catchment in sub-Saharan Africa

Ungauged catchments can be found in many parts of the world, but particularly in sub-Saharan Africa. Information collected in a gauged catchment and its regionalisation to ungauged areas is crucial for water resources assessment. Especially farmers in semi-arid areas are in need of such information. Inter and intra-seasonal rainfall variability...
