dc.description.abstract Climate variability and land use land cover change are major environmental problems and have significant impact on surface and ground water. This impact can negatively affect agricultural production. This study aims to assess the climate variability and land use land cover change impact on surface water in Bir watershed of west Gojam, Climate variability and land use land cover change impact of surface water in the watershed was modeled. The input data were meteorologic, Hydrological, Satellite images and soil data which were collected from MoWIE, NMA, and USGS. Finalized land use map, soil data with look up table, and properly arranged weather data incorporated in QSWAT. The result showed a coefficient of determination (R2) and NS calibration monthly values by using a SUFI2 optimization technique were 0.89 and 0.76 respectively. Similarly, for validation period 0.82 and 0.72 values respectively. The model result showed that the surface run of availability in Bir watershed decreased for the past three decades and maximum and minimum temperature increased by 0.7oc/decade and 0.84oc/decade respectively in it with precipitation declined by 5.43mm/decade. The actual land use land cover change of the watershed is currently dominated by agriculture land (87.7%). Land management interventions are proper options to reduce surface water availability problems. Improving crop varieties can be feasible option and further study of ground water is necessary. en_US
