PROBABILITY AND “RISK” OF GULLY FORMATION

Abstract
An assessment of gully erosion hazard on slopes of drainage basins of small rivers and balkas was fulfilled using the method of extreme parameter calculation. Potential length of gullies was calculated that helped to divide slope drainage basins into “gully-generating” and “non- gully-generating”. The degree of number- and length-realization was evaluated for each gully-generating catch basin as well as the possible increment of gully network length. An approach to assessment of “risk” was suggested. The probability of gully rise was calculated using morphometric characteristics of slope catch basins obtained from topographical maps.
