This dataset is a map of the surface runoff (mm/year) under climate change scenario (2030), modeled using Soil and Water Assessment Tool (SWAT), covering the Central Slopes NRM region. It depicts the climate change scenario of the average amount of surface runoff in mm/year from stream flow from the Hydrologic Response Unit (HRU) for projected year 2030, based from 2001 to 2010 from perturbed climate with A1B emissions scenario under ECHAM 5 and high sensitivity model. It is intended for use at catchment scale. This raster dataset has a cell size of 90m x 90m.
