A Conceptual Approach using the "Limits Concept" for Extending Budyko's Framework for Natural Watersheds and Human-Altered Landscapes
Abstract
A conceptual approach to extend Budyko's Framework using "Limits Concept" is presented. The conceptual approach is first applied to develop equations for mean monthly streamflow and variance of streamflow based on a monthly water balance developed using Budyko's limits. Estimates of mean and variance of monthly streamflow from the semi-empirical equations are compared with the observed estimates for 1373 catchments in the continental United States. Analyses show that the proposed models explain the spatial variability in monthly moments for basins in lower elevations. The talk will also extend the Budyko supply-demand framework for watersheds experiencing significant human influence, particularly to account the impact of reservoir storage on downstream releases. Other potential applications of Budyko Framework for estimating precipitation recycling, sediment transport and difference in sensible heat between urban and rural landscapes will also be presented.
