Luwen Zhuang et al.
The difference between average pressures of two immiscible fluids is commonly assumed to be the same as macroscopic capillary pressure, which is considered to be a function of saturation only. However, under transient conditions, a dependen...
Irrigation, risk aversion, and water right priority under water supply uncertainty [0.03%]
供水不确定性条件下的灌溉、风险规避与水资源优先权关系研究

This paper explores the impacts of a water right's allocative priority-as an indicator of farmers' risk-bearing ability-on land irrigation under water supply uncertainty. We develop and use an economic model to simulate farmers' land irriga...
Revisiting the horizontal redistribution of water in soils: Experiments and numerical modeling [0.03%]
关于土壤水平水分再分配的重新思考：实验与数值模拟研究
L Zhuang,S M Hassanizadeh,P J Kleingeld et al.
L Zhuang et al.
A series of experiments and related numerical simulations were carried out to study one-dimensional water redistribution processes in an unsaturated soil. A long horizontal Plexiglas box was packed as homogenously as possible with sand. The...

Anna K Liljedahl et al.
Difficulties in obtaining accurate precipitation measurements have limited meaningful hydrologic assessment for over a century due to performance challenges of conventional snowfall and rainfall gauges in windy environments. Here, we compar...
A two-dimensional analytical model of vapor intrusion involving vertical heterogeneity [0.03%]

Yijun Yao
In this work, we present an analytical chlorinated vapor intrusion (CVI) model that can estimate source-to-indoor air concentration attenuation by simulating two-dimensional (2-D) vapor concentration profile in vertically heterogeneous soil...
Modeling the isotopic evolution of snowpack and snowmelt: Testing a spatially distributed parsimonious approach [0.03%]
基于空间分布的简约方法模拟积雪及融雪同位素特征变化过程——以美国怀俄明州雪特大坝流域为例

Pertti Ala-Aho et al.
Use of stable water isotopes has become increasingly popular in quantifying water flow paths and travel times in hydrological systems using tracer-aided modeling. In snow-influenced catchments, snowmelt produces a traceable isotopic signal,...
Recharge of low-arsenic aquifers tapped by community wells in Araihazar, Bangladesh, inferred from environmental isotopes [0.03%]

I Mihajlov et al.
More than 100,000 community wells have been installed in the 150-300 m depth range throughout Bangladesh over the past decade to provide low-arsenic drinking water (
The two-phase flow IPTT method for measurement of nonwetting-wetting liquid interfacial areas at higher nonwetting saturations in natural porous media [0.03%]
双流体流动IPTT法测量天然多孔介质中较高非润湿饱和度下非润湿-润湿液体界面面积
Hua Zhong,Asma El Ouni,Dan Lin et al.
Hua Zhong et al.
Interfacial areas between nonwetting-wetting (NW-W) liquids in natural porous media were measured using a modified version of the interfacial partitioning tracer test (IPTT) method that employed simultaneous two-phase flow conditions, which...

Guansheng Liu et al.
The effect of low-concentrations of monorhamnolipid biosurfactant on transport of Pseudomonas aeruginosa ATCC 9027 in natural porous media (silica sand and a sandy soil) was studied with miscible-displacement experiments using artificial gr...
Comparison of Fluid-Fluid Interfacial Areas Measured with X-ray Microtomography and Interfacial Partitioning Tracer Tests for the same Samples [0.03%]
用X射线显微层析和界面分配示踪剂测试测量同一试样的流体-流体界面面积并进行比较
