Analysis of changes in flood regime using a distributed hydrological model: a case study in the Second Songhua River basin, China

This study proposes and tests a new approach to detect and analyze changes in flood regime using a distributed hydrological model (EasyDHM), using the Second Songhua River basin, China, as a case study. Model calibration and parameter sensitivity were used to represent flood regimes in a 60-year series (1954–2013), with three different flood regime periods identified. The changes in flood regime were estimated by model parameters, flood result...
