soil water content is one of the most important parameters for estimating irrigation frequency and providing the plant’s water requirement. since measurement of soil water content is both expensive and time consuming, water movement models are used to estimate these values. in this study, leachw model was used to estimate soil water content for two “dry” (20-29 aug) and “wet” (1-6 jul) periods ...

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 (...

Purpose : Over the seventy years, various soil erosion modeling methods were developed in world with different input requirements and complexity. Some of these models have been applied Sri Lanka covering several regions country at scenarios over past twenty years. Thus, prime objective this study is to compare commonly practiced GIS/ RS based assessment derivation techniques model parameters us...
