On recent growth of gullies at Tadjikistan

Abstract

Field studies and cartographic analysis allowed compiling a schematic map showing intensity of gullies' growth at Tadjikistan and recent state of gully erosion. The author outlined seven sites of most intensive gully erosion. Maximum values registered of gully growth are 82,5 m under undisturbed vegetation and 674,7 m per year at irrigated lands. Intensity of gullies' growth under natural conditions has been proved to follow vertical zonality, maximum value of the growth is registered at middle mountain zone, at irrigated lands most intensive growth is at valleys. Quantitative data are given for individual years and regions.
