The net rainfall over a river basin will produce the storm runoff hydrograph. As the storm runoff is generated from different locations within the basin, a time distribution of the storm runoff with time will be observed. To calculate the storm hydrograph in a location along the river, it is necessary to account for the transport of the water from within the river basin towards this location. Although the transport mechanisms may be complex and consist of flow over the surface, flow within ditches and rivers and subsurface storm flow, this transport is here referred to as surface runoff and this course mainly deals with the processes described above.
