✦ Synopsis

Abstract

The main purpose of the research described in this contribution was to apply a conceptual hydrological model to predict runoff volumes when El Niño southern oscillation (ENSO) events occur. Statistical analysis was used to assess the impact of ENSO events on rainfall and runoff variables across the Chopim River basin. A conceptual model was calibrated and validated to simulate the rainfall–runoff processes within the basin. An extended runoff volume prediction procedure was applied to derive forecasts of runoff volumes for different lead times for the different rainfall data series.

## Abstract Snowmelt runoff dominates streamflow in the Upper Rio Grande (URG) basin of New Mexico and Colorado. Annual variations in streamflow timing and volume at most stations in the region are strongly influenced by the El Niño–southern oscillation (ENSO) through its modulation of the seasonal
