Soil moisture is an important hydrologic state variable critical to successful hydroclimatic and environmental predictions. Soil moisture varies both in space and time because of spatio-temporal variations in precipitation, soil properties, topographic features, and vegetation characteristics. In recent years, airand space-borne remote sensing campaigns have successfully demonstrated the use of...

Abstract. The application of large manure on the agricultural lands that derived from Concentrated Animal Feeding Operations (CAFOs) could cause excess nutrients such as nitrogen and phosphorus transport to groundwater through vadose (unsaturated) zone. objective this study is follows: (1) compare in zone at different Land Management Units (LMUs) for three consecutive years (2004-06) using HYDR...

The process of how soil moisture profiles evolve into the and reach root zone could be estimated by solving appropriate strong nonlinear Richards’ equation. nonlinearity equation occurs because diffusivity D is generally an exponential function water content. In this work, boundary conditions physical problem are considered fuzzy for various reasons (e.g., machine impression, human errors, etc....
