Which one is incorrect about assumptions made that are inherent to the unit hydrograph: Rainfall excesses of equal duration are assumed to produce hydrographs with equivalent time bases regardless of the intensity of the rain. O The time distribution of direct runoff is assumed to dependent on antecedent precipitation. Rainfall distribution is assumed to be the same for all storms of equal duration, both spatially and temporally. O Direct runoff ordinates for a storm of a given duration are assumed to be directly proportional to rainfall excess volumes. Thus, twice the rainfall produces a doubling of hydrograph ordinates.

A small watershed has four rainfall gages located in the figure below. Total rainfallrecorded at each gage during a storm event is listed in the table. Compute the mean areal rainfallfor this storm using (a) arithmetic averaging and (b) the Thiessen method.
Following catchment area includes 20-years of annual rainfall data. If the catchment average rainfall is to be calculated in each year using the Thiessen Polygon method or the Isohyetal method, explain the method you select and reasons. Consider that the both are area-average methods and give reasonably similar answers when the rain gauge network is dense as shown in the figure.

What is the difference between a streamflow hydrograph and a unit hydrograph? The UH is a special case of a streamflow hydrograph in which the rainfall depth is equal to 1 unit They are the same. The UH is a special case of a streamflow hydrograph in which the surface runoff is equal to 1 unit The streamflow hydrograph is caused by total rainfall, while the unit hydrograph is from the same rainfall, less losses.
