The study examines the possibility of simulating time series of stream flows for ungauged catchments based on hydrological similarity. As an example the mountainous, semiarid Karkheh river basin (50,764 km2) of Iran is presented. The frequently applied HBV model was applied to simulate daily stre...

The study examines the possibility of simulating time series of streamflows for poorly gauged catchments based on hydrological similarity. The data of 11 gauged catchments (475-2522 km2), located in the mountainous semi-arid Karkheh river basin of Iran, is used to develop the procedure. The well-...

Streamflow data is a prerequisite for planning and management of water resources. However, in many cases, observed streamflow data are not available or the records are too short or of insufficient quality. This undermines the informed planning and management of water resources at a specific site ...

Reduction of input uncertainty is a challenge in hydrological modeling. The widely used model Soil Water Assessment Tool (SWAT) uses the data of a precipitation gauge nearest to the centroid of each subcatchment as an input for that subcatchment. This may not represent overall catchment precipita...

The brief discusses the key messages that transpired during the Conference on Scaling held on 29─30 November 2018 at the Melia Hotel in Hanoi, hosted by CCAFS SEA, co-hosted by ACIAR and GIZ, and funded by a CCAFS Small Grant Cross-CRP Networking. The conference main points include: scaling up ag...
