Understanding the Impact of Human Interventions on the Hydrology of Nile Basin Headwaters, the Case of Upper Tekeze Catchments

Availability and distributions of water resources in catchments are influenced by various natural and anthropogenic factors. Human-induced environmental changes are the most key factors controlling the hydrological flows of semi-arid catchments. Land degradation, water scarcity and inefficient utilization of available water resources continue to be key constraints for socio-economic development in the Nile headwater catchments in particular over the Ethiopian catchment. This research investigates impact of landscape anthropogenic changes on the hydrological processes and variability of flows in the Upper Tekeze basin (a tributary of the Nile). The hydrology of the basin is investigated through analysis of hydro-climatic data, remote sensing techniques, new field measurements and parsimonious hydrological models.
The collection of evidences confirm that human-induced environmental changes are the most important causes of change in hydrological processes in those catchments. This thesis provides a clear understanding on how large-scale implementations of catchment management interventions can influence the overall hydrological response. It is also indicated in this research that development of a parsimonious dynamic hydrological model for a specific catchment can improve understanding of the hydrological response to dynamic environmental changes. This thesis underlined that rainfall-runoff relationship in semi-arid areas is strongly non-uniform compared to that of humid environments and application of hydrological models in such catchments need special attention.
By September we will present an overview of SENSE dissertations on this page, with links to the full texts of the dissertations.
