Gully in arid climate.

The 100th meridian west (solid line) has long been considered the divide between the relatively moist eastern United States, and the more arid West. Climate change may already have started shifting the divide eastward (dotted line). One can literally step over the meridian line, but the boundary it represents is more gradual.The gully area of the Loess Plateau is located in a region characterized by a combination of semi-arid and semi-humid conditions, with a dry climate, deep soil layers, and deeply submerged groundwater . Soil moisture is mainly replenished by precipitation.The badland area is located in the Spanish Central System, Province of Segovia (41° 9′ 30′′N; 3° 48′ 30′′ W) at an elevation of 1065 m ( Fig. 1 ). Analyses were performed in a ...In spite of many research efforts on gully erosion, there is an argument about causes of gully erosion among researchers. Causes of gully erosion can be classified into three categories: human impact (Bork et al., 2001, Starr, 1989), climate change (Gregory and Moore, 1931) and intrinsic changes (Schumm and Hadley, 1957). Examples
