Theories of Gully Formation

Gully formation theories explain how narrow channels develop on slopes mainly due to water erosion. When rain falls, it washes away soil, especially on steep surfaces or in areas with little vegetation. Over time, continuous runoff enlarges these channels into gullies. Theories suggest factors like heavy rainfall, soil type, land use, and slope gradient influence gully development. Some propose that concentrated water flow gradually erodes the land, while others emphasize the importance of land management practices. Overall, gullies form through a combination of water erosion processes shaped by environmental and human factors.
