Be able to define and compute the topographic wetness index and describe its role and use in TOPMODEL runoff calculations. Be able to use TOPMODEL principles to calculate the spatial distribution of soil moisture deficit and use this information in the calculation of runoff using appropriate GIS tools. From Mays, 2011, Ground and Surface Water Hydrology. A D hour unit hydrograph is the characteristic response of a given watershed to a unit volume (e.g. 1 in or cm) of effective water input (usually rain) applied at a constant rate for D hours.
