Stochastic Response of Storage Function Model for Flood Runoff

All real hydrologic processes are more or less stochastic. While the dynamics for the runoff process are described by differential equations, strictly speaking, runoff phenomena are best expressed by stochastic differential equations. Stochastic differential equations are grouped into three classes: 1 Initial conditions are described as stochastic or probability. 2 The parameters included in differential equations are random variables. 3 Forcing terms are random variables.
