Flood Regime Characterization (FRC) for Matlab

This program is an attempt to transform the methods discussed in the companion paper into a portable computer program so that they can be used by researchers and managers on other watersheds in order to characterize a flood regime. The main inputs to the program are a daily streamflow record and a set of flood duration and magnitude thresholds that have some meaningful connection to the hydrologic, geomorphic, and/or ecological processes in the specific watershed. The main outputs are a list of floods, flood types, and water year types along with useful statistics for each list and estimates of the frequency of each flood type and water year type.
