Dataset
Hydroacoustic monitoring of bedload and suspended sediment sampling of the West Rapti river, Nepal
Abstract
This dataset contains amplitude and frequency metrics calculated from 30s hydrophone recordings in the West Rapti river in the monsoon season of 2024, alongside water level data supplied by the department of Hydrology and Meteorology. Recordings are made at various amplification gains, which are specified within datasets. There are also suspended sediment concentration data, which was measured daily during the 2024 monsoon.

| Data lineage: |
Hydrophones recorded 30s wav files every 15-20 minutes at various gain amplifications, specified in dataset files. Sample rate is 48 kHz. Data was processed in Python using scikit-maad to calculate RMS amplitude and spectral centroid of the recordings. Suspended sediment was measured manually by filtering techniques at 12:00 each day. |
| Data Quality: |
Amplitude and spectral centroid calculated using conventional relationships from frequency-filtered data to exclude frequencies below 2 kHz, otherwise supplied as-is. Where possible, the datasets contain % of clipped files, determined from clipdetect package. Suspended sediment was dried thoroughly in a lab oven prior to weighing with a mass balance of 0.0001 g precision.
