Spatial and Temporal Evaluation of Water Budget at Gumara Watershed in Ethiopia.

Water is one of major factors for better and worse human life. Humans would be protected from water (flooding and drought) and water would be protected from humans (pollution and over exploitation). Flowing nature of water makes it very important since it is used as medium of transmission of substances (sediments and pollutants), medium of communication (upstream-downstream complex) and its higher uncertainty of availability (distribution and recurrence). Hydrological cycle and modeling play roles to handle such peculiarities for better water management.

In this study, water budget will be analyzed in Gumara watershed of Blue Nile Basin, Ethiopia, where water and its productivity is hot issue to a way out of poverty and subsistence crop-livestock production and for better ecosystem functioning. Existing water use and distribution was assessed with case studies and mining long-term measured data-base of the area. Missing data is filled with different statistical methods. Soil and Water Assessment Tool (SWAT) model will be used to get calibrated model, scale dependent simulated water budget scenarios and water management alternatives.
