Physical factors affect the drainage basin cycle Relief Has a role in influencing the type and amount of precipitation overall and the amount of evaporation, i.e. the major inputs and outputs. It also has an impact of the vegetation type. Climate Determines the amount of infiltration and throughflow and, indirectly, the type of vegetation Vegetation Can impact on the subsurface processes such as percolation and groundwater flow (and, therefore, on aquifers). Indirectly, it can alter soil formation Geology Can impact on the amount of precipitation. Slopes can affect the amount of runoff Soils The presence or absence of this can have a major impact on the amount of interception, infiltration and occurrence of overland flow, as well as transpiration rates.
