HYDRORECESSION

Toolbox for streamflow recession curves analysis through mathematical model fitting.

HYDRORECESSION: The HYDRORECESSION GUI is a beta version developed at the Institute of Engineering of the National Autonomous University of Mexico (II-UNAM). HYDRORECESSION was developed in a Matlab version 2010b for Microsoft Windows 64-bits, and it can work in later versions.

Streamflow recession analysis from observed hydrographs allows to extract information about the storage-discharge relationship of a catchment and some of their groundwater hydraulic properties. The HYDRORECESSION is a graphical user interface for Matlab and it was developed to analyse streamflow recession curves with the support of different tools. The software extracts hydrograph recessions segments with three different methods (Vogel, Brutsaert and Aksoy) that are later analysed with four of the most useful models to simulate recession curves (Maillet, Boussinesq, Coutagne and Wittenberg) and it includes four parameter-fitting techniques (linear regression, lower envelop, data binning and mean squared error). HYDRORECESSION offers tools to parameterize a linear and no linear storage-outflow relationship and it is useful for regionalization, catchment classification, baseflow separation, hydrological modeling and low flows prediction.
