Abstract	The purpose of this study is to evaluate the impact of land use change on catchment hydrology. To do this evaluation, changes in the state of land use were mapped by classifying selected landsat satellite images based on eleven land use classes which were found in the catchment. The classifications were assessed using GEOVIS and processed in ArcView GIS with the help of ground information. The hydrologic impacts of the detected land use changes were analyzed within catchment. Results obtained shows that forests land declined by 57% while agricultural land and built-up area expanded by 10 and 156% respectively over the study period. Evaluation of the impact of land use changes revealed that there was an increase of surface runoff from 4.12 to 110.96 mm and sediment yield from 0.43 to 20.10 t/ha within the catchment due to impact of the land use change. Simulated model results showed an increase of surface runoff in the catchment with the highest being of the post change period 2001 which had severe land use changes. The results were found that they can be used by catchment stakeholders and policy makers to address challenges brought by the catchment degradation. The results will further help in making informed decisions in selecting and developing viable catchment management options that will promote sustainable utilization of land and water resources within Wundanyi River Catchment.
