Estimate of drainage water behaviour in shallow lakes

Abstract

A theoretical estimate of the explicit time dependence of a drainage water of shallow lakes is presented as an important contribution for understanding the lake dynamics. This information can be obtained from a sum of functions, largely used in fitting of experimental data. These functions were chosen because their centre and weight yield a good description of the water basin behaviour. The coefficients of these functions are here extracted using results of measured and / or calculated data for the state variables describing the shallow West Lake, Hangzou. This procedure can also be applied to other shallow lakes, generating geological information about their drainage basin, which is one of the most important parameters to describe their micrometeorological behaviour. One concludes this work emphasizing the relevance of the explicit time dependence of the drainage variables and the requirement of measured data to validate this approach.
