Determining the applicability of remote sensing methods and weather station rainfall data to study excavated gully volume

dataset

Data provided in the hillslope gradient dataset relates to hillslope gradient of gullies calculated using two digital elevation models (DEM) of different spatial resolutions as well as the hillslope gradient of gullies collected during a field visit. The dataset that relates to rainfall data suitability includes average and maximum amount of rainfall at selected weather stations and the excavated volumes of gullies in the vicinity of each weather station. Thirdly, the dataset relating to LiDAR, Google Earth, and physical measurements includes the volume of gullies collected during the field visit and gully volume calculated from LiDAR imagery. Furthermore, the dataset includes the aerial extent of gullies measured on Google Earth, the gully aerial extent calculated from the LiDAR imagery, as well as the percentage difference between the measurements. Finally, the fieldwork dataset indicates the coordinates of gullies that were measured in the field, as well as the length, width, and depth measurement results. The dataset also indicates the calculated aerial extent and gully volumes.
