Abstract
There are several approaches for the analysis of baseflow which include different kind of conceptual models and theoretical analysis. The concepts of linear and nonlinear storage are often used in modeling the baseflow and the nonlinear relationship between baseflow (Q) and moisture storage (S) can be described as S = aQb. Boussinesq equation is used to predict the baseflow, and the results are as good as the estimation by nonlinear storage. The purpose of this paper is to discuss the relationship between nonlinear storage concept and the Boussinesq Equation. The parameters a in nonlinear storage modeling will be discussed. By using the observed streamflow data in Taiwan, the physical properties of parameter a will be identified. The present study concentrated on the structure of baseflow modeling and their parameters.
