On parameterization of heat conduction in coupled soil water and heat flow modelling
advective heat flux dual-permeability model preferential flow soil heat transport soil thermal conductivity surface energy balance
2015/3/5
Soil water and heat transport plays an important role in various hydrologic, agricultural, and industrial applications. Accordingly, an increasing attention is paid to relevant simulation models. In t...
Comparison of two sensors ECH2O EC-5 and SM200 for measuring soil water content
bulk density CaCO3 ECH20 soil moisture sensor EC-5 fraction of sand particles SM200 sensor soil and soil water salinity soils of the Czech Republic soil water content
2015/3/3
The goal of this study was calibration of the ECH20 soil moisture sensor EC-5 and the sensor SM200 for selected soils of the Czech Republic. Based on the soil maps of the Czech Republic and various cl...
Variability of soil water-physical properties in a small catchment of the Loess Plateau, China
Geostatistical analysis regression analysis rainfall seasn land use pattern
2011/1/13
Data from the Donggou small catchment, located in a typical wind-water erosion crisscross zone on the Loess Plateau of China, illustrate the spatial variability of soil water-physical properties of di...
不同土层土壤水分特征曲线的空间变异及其影响因素（Spatial Variability of Soil Water Retention Curve in Different Soil Layers and Its Affecting Factors）
土壤水分特征曲线 空间变异 多重分形
2010/1/28
利用多重分形和联合多重分形方法，对陕西杨凌地区0～20cm和20～40cm土层van Genuchten模型参数的空间变异性及其影响因素进行了研究。结果表明：0～20cm和20～40cm土层参数α都具有明显的多重分形特征，空间变异性较强，且分别是由低值和高值分布引起的；参数n和θs的多重分形特征不明显，空间变异性较弱。0～20cm和20～40cm土层van Genuchten模型参数与土壤物理特性...

2009/9/10
TDR (Time-domain reflectometry) is an advanced method for monitoring the water content in fields.TDR measurements can provide accurate information about vegetation effects on both spatial and temporal...
Water-Extraction by Split-Roots of Sesbania and Pigeon Pea Exposed to Spatially Heterogeneous Distribution of Soil Water
ABA Deep root Drought stress Groundwater Root distribution Specific root length Stomatal behaviour Water logging
2009/7/24
Previous studies have suggested that the deep roots of sesbania (Sesbania sesban) function less efficiently in water acquisition than those of pigeon pea (Cajanus cajan) despite similar rooting depths...
