Evaluating Multi‐Model and Multi‐Metric Approaches to Low‐Flow Simulation in Irish Catchments

Hydrological Processes, Volume 40, Issue 2, February 2026.
Daily streamflow from 125 catchments was simulated using 47 conceptual models available in MARRMoT framework. The models were calibrated using two objective functions (log NSE and inverse KGE) focusing low flows. Model performances and choice of objective function were assessed against 18 catchment characteristics. ABSTRACT Climate change has increased
