I present lunar landslides that bear a striking resemblance to some martian gullies, despite the lack of water on the Moon both today and in the past. This observation indicates that gully features can be formed via a dry landslide mechanism. Thus on Mars, morphology alone is insufficient to determine the mechanism of formation of these features. Introduction: In 2000, Malin and Edgett (1) repo...

Purpose: to determine patterns of formation hydrographic network elements depending on the melt-and rainwater runoff and soil losses. Materials methods. The studies were carried out in upper reaches Bolshoy Log gully system, which is a part land use experimental farm “Polevoy” Federal Rostov Agrarian Research Center, with an area 2070 hectares, more than 70 % arable land. Soils are ordinary che...

Sediment management is guided by both technology and local so-cioeconomic conditions.llpstreaa management in China emphasizesgully control. Warping of land is practiced wherever conditionspermit. Both make use of sediment as an asset. Sediment is alsoused to enlarge Yellov River levees to 50 to 70 m wide.Useful storage capacity of a large reservoir may be preservedpe...

Introduction: Two main theories of gully formation on Mars exist depending on the source of water. One holds that water was released from the subsurface [1]. The other proposes that water is deposited as nearsurface ice or snow from the atmosphere and is subsequently melted by insolation [2-4]. In this paper we applied fractal theory to study a gully's head alcove in different orientations of a...
