Abstract

Linking the results of two research topics on rainfall and streamflow stochastic models, the relationship between total and effective rainfall is studied here. The short time streamflow process is examined concerning the climatic and hydrogeological characters of the watershed, identifying four distinct components giving rise to runoff. In this way the watershed can be regarded as a four-component linear system, whose input is the effective rainfall. Finally, the streamflow model is used as an effective rainfall inverse estimator, allowing the analysis of the links between total and effective rainfall assuming a simple transformation law. The determination of this law is performed by applying a stochastic model, whose parameters are estimated on the companion series of recorded total rainfall and reconstructed effective rainfall. An application to a case study shows the effectiveness of the proposed approach.
