New Methodology for Determining of the Ecological Flow with Hydrometric Data

Abstract

Although there are several methods to calculate the ecological flow, however, in Ecuador did not develop yet a technique that suits the reality of the water systems. Therefore, we proposed a new methodology to determine the ecological flow through of hydrometric data such as minimum flows, average flow and monthly peak flows in a specific basin. The values obtained with the applied methodology are unique for the studied basin and do not correspond to percentage flow. This is fundamental since engineers use a variety of methods and need to choose at its discretion the best fitting one.
