Full Description
Hydroclimatology has emerged as a new discipline in line with increasing awareness of the connected nature of land-surface-atmosphere processes. Changes in landuse affect the atmospheric moisture conditions, not only locally but also at a continental scale. Similarly, climate change influences river basin hydrology and water resources. A good understanding of the atmospheric contribution to the regional water cycle is important for sound (integrated) water resources planning and management at river basin scale. The Nile Basin is characterized by increasing water demands in the downstream areas and high evaporation from the Upper Nile swamps. This has led to the planning and construction of river short-cut channels to intercept the water feeding the wetlands. Despite the importance of the wetlands to the local environment, and, it is thought, as a supplier of additional Nile water, its exact hydrology and its interaction with the climate is largely unknown. This study aims
