High-frequency hydrology and suspended sediment dataset for the Nakkhu River catchment, Nepal

"Suspended sediment dynamics in an urban, mountain catchment in Nepal" This dataset contains hydrological and suspended sediment data from the Nakkhu River catchment in Kathmandu Valley, Nepal, collected during the 2023 monsoon monitoring period (May–October 2023). The dataset includes: 1. 30-minute hydrological and sediment-sensor data. 2. Calibration data used to develop the stage–discharge, discharge–SSC, and backscatter–SSC relationships. 3. Rating-curve-derived suspended sediment load data at multiple temporal resolutions used for the temporal-resolution sensitivity analysis. The paper associated with this dataset: Prajapati, R., et al.
