These data contain bank strength measurements in a 100 km reach of the Solimões River from Sep/Oct 2022 recorded with a shear vane and a cohesion strength meter. In addition, processed satellite (Landsat) imagery from 1984-2021 was used to calculate erosional and depositional area in three 50-120 km long reaches in the Solimoes River presented here as shape-files. Processed Corona imagery 1967 for a 120 km long reach in the Solimoes River shows the banklines and bar outlines. A spreadsheet provides erosional and depositional area at 20-km sections along the 1,600km of the Solimoes River that were based on measuring floodplain width from a digital elevation model (FABDEM). We also attach a GeoTIFF file of the multibeam echo sounder (MBES) data collected during the field campaign in a 20-km long reach in the Solimoes River

Provenance & quality

Field data collection of bank strength and MBES data collection. Conversion of bank strength measurements into kPa using available calibration equations and statistical analysis. MBES data was cleaned and regridded using appropriate software.
Landsat imagery was downloaded from Google Earth Engine as composite images between 1984-88 and 2019-22 and converted into binary maps of water and dry cells for each period. Small channels and lakes were removed in ArcGIS and split into sections of approximately 20- and 10-km lengths.
GIS analysis was carried out by downloading shape-files from the Global Water Surface Explorer (https://global-surface-water.appspot.com/) for 1984 and 2019 along both banks of the entire Solimoes River. Net erosional and depositional area was computed as the sum of along 20-km reaches. Association and disassociation with cohesive terraces that determined based on a digital elevation model for 2000 for each reach and bank.
Corona imagery was purchased and georeferenced using GIS software.
