Our estimates of surface erosion by rills and wash are very uncertain as we lack data
Research gap analysis derived from 3 earth_science papers in our local library.
The gap
Our estimates of surface erosion by rills and wash are very uncertain as we lack data on sediment concentrations and reservoir sedimentation can not directly be used as a measure of the sediment yield from the basin as data on the trap efficienty of the reservoir is not available.
Evidence profile
Sourced from the stated challenges and discussion of the source papers, classified as general, drawn from work published between 1985 and 2026, spanning 3 journals. Those papers have been cited 13 times in total.

- Impact of Water Erosion and Erosion Control Activities on River Ecosystems: A Review (2026) · Environments · doi
Predicting whether erosion or deposition will occur remains a significant challenge. The balance between the positive and negative effects of erosion control activities depends strongly on local environmental conditions and the scale of implementation. There is a need to develop future models that capture the natural complexity of rivers.
