Hydraulic Resistance of Soil Surface Seals in Irrigated Furrows

Effect of Slope Gradient and Soil Physical Properties on Soil Loss in Furrows of Rainfed Farms

This study was conducted to investigate the effect of slope gradient and soil physical properties (grain size distribution, bulk density, aggregate stability and permeability) on water erosion in the furrows of rainfed farms under fallow conditions. The furrows with 6 m length were installed in five rainfed farms with 6.1, 10.6, 14.8, 20.7 and 27.1% slope steepness at three replications. Resul...

Land Surface Modeling with Enhanced Considerations of Soil Hydraulic Properties

Simulation of heat and water transfer in a surface irrigated, cropped sandy soil

Field experiments were conducted to validate a one-dimensional numerical Simple Soil Plant Atmospheric Transfer (SiSPAT) model that simulates heat and water transfer through the root zone of a surface irrigated, cropped sandy soil. The model accounts for the dominant processes involved in water and heat transfer in a cropped soil. Model validation used field experimental data from 2004 and sugg...

Near - Surface Soil Moisture Assimilation for Quantifying Effective Soil Hydraulic Properties under Different Hydroclimatic Conditions

39 S oil hydraulic parameters are essential input to most hydrologic and climatic models (Mohanty et al., 2002; Mohanty and Zhu, 2007). Th ey are used to defi ne the hydraulic characteristics of the soil vital in modeling soil moisture and fl ux in the unsaturated zone near the land–atmosphere boundary. At the scale of model applications, it is very important to defi ne the appropriate paramete...

evaluation of a two dimensional infiltration function for irrigated furrows

abstract this study addresses two dimensional infiltration from irrigated furrows. the basic approach is to develop a two-dimensional infiltration as a combination of the corresponding one-dimensional vertical and an edge effect. the edge effect is the difference between the cumulative infiltration per unit of adjusted wetting perimeter and the corresponding one-dimensional infiltration. this a...
