This research work exposes the results of our study about cartographic and qualitative estimation hydric erosion watershed talangaï (Brazzaville) following PAP/RAC approach, tele detection’s data geographical information system in order to elaborate thematic cards by enlightening phenomenon. In this talangaï, phenomenon became recurrent causes more spectacular worrings. As a matter fact, except...

The hill tribes in Thailand traditionally depend on rotational shifting cultivation (RSC). However, insufficient understanding remains post-fire soil properties and erodibility ( k -values) with fallow years. To address this gap, the levels of organic carbon (SOC), total nitrogen (STN), nutrients, after fire RSC were investigated. Topsoil (0–10 cm) samples from sites 4 (RSC-4Y), 5 (RSC-5Y), 7 (...

Abstract Soil functions such as water storage, soil filtration, and reducing reservoir life due to sediment load are directly affected by the process of “soil erosion.” The Universal Loss Equation was adopted predict erodibility factor for watersheds feeding Al-Shewicha trough. K -average factor’s determined value 0.156, indicating that -factor had substantial variability. values linked high sa...

This paper describes spatial modeling methods to identify wind erosion hazard (WEH) areas across Australia using the recently available time-series products of satellitederived ground cover, soil moisture and wind speed. We implemented the approach and data sets in a geographic information system to produce WEH maps for Australia at 500 m ground resolution on a monthly basis for the recent thir...
