Answer the following statement(s) true (T) or false (F)
1. Evapotranspiration is the loss of water vapor from plants to the atmosphere. 2. All drainage basins have the same three types of flow along the hydraulic path. 3. A graph showing the entire relationship between runoff and time for a given rainfall event is called a hydrograph. 4. Direct measurement is used to compute hydrographs for large river basins in which one or more measuring stations are used to record actual hydrographs for every major storm over a number of years. 5. In computing a runoff hydrograph, if the delineated drainage basin is too large or not sufficiently homogeneous, it must be subdivided into smaller units called subareas or subbasins.
