Weblumped over the whole watershed. The unit hydrograph is defined as a direct runoff hydrograph resulting from a unit depth of excess rainfall for an effective duration. A spatially distributed unit hydrograph is a unit hydrograph derived from a spatially distributed excess rainfall. It is based on time area rainfall runoff routing technique. WebFig. 15.16 is self-explanatory and shows how a run-off hydrograph is constructed from a unit hydrograph. Limitations to the Use of Unit Hydrographs: 1. Its use is limited to areas about 5000 sq. kilometres since similar rainfall distribution over a large area from storm to storm is rarely possible. 2.
