| Abstract |
Drainage basin discharge may be simulated by treating the drainage basin as a storage-discharge phenomenon. Stream hydrograph analysis is used to estimate the position of a curve showing the relationship of discharge to expected values of storage. Hydrograph analysis is also used to estimate graphical relationships between a rainfall index and rainfall recharge of basin storage, and to estimate graphical relationships between a snowmelt index and snowmelt recharge of basin storage. Snowfall in the basin is also estimated from a weather index. These estimates are used in conjunction with a water budget equation to approximate a discharge hydrograph for the basin. The discharge hydrograph is computed by a FORTRAN IV program called HYDROSIM. The computed hydrograph is changed by trial and error adjustment of the aforementioned graphs until a satisfactory correspondence between simulated and real hydrographs is obtained. (Author) |
