  "abstract": "Study region: Kathmandu Valley, Nepal: the Bagmati (gauged donor), Bishnumati (gauged proxy) and Manohara (ungauged) river basins. Study focus: Streamflow estimation in ungauged basins is a major challenge for water resource and flood disaster management. This study compared two lumped hydrological models, HBV and HEC-HMS, and tested whether parameters calibrated in a gauged basin can be transferred without adjustment to a gauged proxy basin and to an ungauged basin. Continuous daily simulation, one-at-a-time sensitivity analysis, Taylor diagrams and Generalized Likelihood Uncertainty Estimation (GLUE) were used. New hydrological insights for the region: In the Bagmati basin, HBV outperformed HEC-HMS in validation (NSE 0.71 vs 0.57; R 2 0.79 vs 0.60; peak error 2.1% vs 43.6%) and had the higher NSE in five of seven individual years. HBV's GLUE bounds were narrower in both periods but enclosed fewer observations in calibration (67% vs 82%) and slightly more in validation (70% vs 68%). Direct transfer to the more urbanized Bishnumati basin was unsatisfactory for both models (NSE 0.39 for HBV and 0.44 for HEC-HMS), although HBV reproduced the observed peak more closely (error 10.5% vs 35.3%). In the ungauged Manohara basin, HBV simulations agreed with Catchment Area Ratio (CAR)-derived discharge (NSE 0.63; R 2 0.70), which is a consistency check rather than independent validation. Model structure affected performance in the donor basin, whereas catchment differences together with data limitations may explain the weak transfer to Bishnumati. With one donor and two recipient basins, these findings are case-specific, and local gauging remains necessary.",
