Introduction: The latitude-dependent distribution [1-4] and non-uniform orientation [5-9] of gullies on Mars indicate that their formation is controlled by climate conditions at the surface within the last million years [10-11], while their global distribution [2,4] and morphology [12-13] show direct correlations with the ice-rich Latitude Dependent Mantle (LDM), a potential source for melting....

Introduction: Martian gullies were first identified by Malin and Edgett [1]. Previous work [2] has examined the characteristics of gullies in the southern hemisphere in detail. Less detailed work has been done for the northern hemisphere [3,4]. Gullies are found predominantly in the midlatitudes of both hemispheres between 30°-50° [1,2], which implies a thermal control on their formation. Sever...

Accurate mapping and measurement of erosion channels is necessary to accurately estimate the impact of channeled erosion in an area. Field surveys can provide optimal quantitative results, but they are only applicable to small areas. Recently, photogrammetric techniques have been applied to small format aerial photographs that were taken by UAVs. Few studies have applied photogrammetry for mapp...

Cellulosilyticum sp. strain I15G10I2 was isolated from a coal seam gas water treatment pond at the Spring Gully water treatment facility, Roma, Queensland, Australia. Analysis of the genome of 4,489,861 bp and G+C content of 35.23% revealed that strain I15G10I2 shared limited similarity to members of the genus Cellulosilyticum, family Lachnospiraceae.

erosion is one of the important social-economic problems in iraniancatchments that have been posed by surface water vastness and runoff production. so, thestudy of water resources, soil erosion and effective factors is of high importance. gullyerosion also extends in many parts of iran and its study particularly in viewpoint ofsediment yield is therefore very important and should be taken into ...

The widespread hillslope- and gully-erosion in Liaoning Province of Northeast China, pose serious challenges to the local agricultural production. Hillslope- have typically been studied separately; however, there has little investigation on relationship these two types erosion. In this study, coupling from perspectives erosion intensity land use, as well slope gradient, aspect, shape, was analy...
