ABSTRACT
Land use and hydrologic processes are believed to be interlinked whereby changes in land use affects hydrologic processes such as interception, evapotranspiration, infiltration, stream flow and runoff. This chapter investigates hydrologic response to land-use change in the Jedeb catchment of the Abbay basin. It also investigates the semi-dynamic feedback between land-use change and hydrology. The chapter discusses a physically based distributed hydrologic model and a dynamic land-use change model for modelling the hydrology and for producing yearly land-use maps. It provides a new approach for the analysis of effects of land-use change on hydrologic components. Instead of taking a static land-use map or few episodes of land-use maps or using varying land-use proportions in hydrologic models, a separate land-use change model based on various socio-environmental land-use change drivers was developed. The chapter describes the study area and the method used in the analysis.
