Gully erosion in India: Geo‐environmental controls and region‐specific characteristics
Geographical Research, Volume 64, Issue 2, May 2026.Spatial statistical analyses using a novel spatial database of India‧s gully erosion landforms revealed that India has six major gullying‐affected regions, three of which (EU, DU, and KCH) are dominated by gully systems (gully networks), with badlands (vast intensely gullied landscapes) being predominant in the other three regions (YB, GP, and RU ...
