Soil degradation induced by gully erosion represents a worldwide problem in the many arid and semi-arid countries, such as Iran. This study assessed: (1) importance of variables that control using Boruta algorithm, (2) relationship among causative gullied locations evidential belief function model (EBF), (3) development algorithms boosted regression tree (BRT) support vector machine (SVM). Base...

Here we present a method for predicting debris flow run-out based on numerical model shallow water flows, using case study conducted Xulong Gully, proposed dam site hydropower station in the upper reaches of Jinsha River. A field investigation and remote sensing interpretation methods were used to develop comprehensive evaluation zones calculate potential provenance volume Gully. Particle-size ...

The occurrence and development of erosion gully will increase the area soil continuously erode cultivated land. treatment is swing in black region Northeast China. However, they are all directed at typical area, while caused by semi-arid less concerned. study uses a combination RS census data. Exploring number status development, survey results show that :the large, most them developmental gull...

Introduction: Carbon dioxide is Mars’ primary atmospheric constituent [1] and is an active and dynamic driver of Martian surface evolution. Kieffer’s hypothesis that gas venting from beneath seasonally deposited south polar CO2 slabs modifies the Martian landscape [2], spearheaded an advent of CO2 modelling. In a climate in which it is difficult to sustain liquid water, the agency of sublimatio...

Gully Land Consolidation (GLC) is a proven method to create farmlands and increase crop yields in the Loess Hilly Region, China. However, GLC influences phreatic water transformation might cause disasters, such as salinization swamping. For exploring influence of on mitigating series indoor experiments were conducted artificial rainfall hall. Then, we simulated patterns under more conditions wi...

Dasht Yari plain is nearly 580,000 hectares which is under engraving gully erosion and unfortunately the gully development rate is increased in the recent decades. Satellite images may provide quick, extensive, and valuable information for the interpretation of morphometric characterstics of gully erosion expansion due to having attributes such as time series, relatively low cost, large coverag...

The Loess Plateau has long been suffering from serious soil erosion of which the slope-gully system is now dominant. characterized with distinctive distribution zones consisting inner and inter gully areas wherein patterns spatially vary, acting as both sediment source dominant water transport mechanism. In this paper, a substantial body research reviewed concentrating on processes control prac...
