An enhanced temperature index model for debris-covered glaciers accounting for thickness effect [0.03%]
考虑厚度影响的冰川增温指数模型改进
M Carenzo,F Pellicciotti,J Mabillard et al.
M Carenzo et al.
Debris-covered glaciers are increasingly studied because it is assumed that debris cover extent and thickness could increase in a warming climate, with more regular rockfalls from the surrounding slopes and more englacial melt-out material....
Definition and solution of a stochastic inverse problem for the Manning's n parameter field in hydrodynamic models [0.03%]
曼宁粗糙度参数的随机反问题的定义及求解方法在水动力模型中的应用研究
T Butler,L Graham,D Estep et al.
T Butler et al.
The uncertainty in spatially heterogeneous Manning's n fields is quantified using a novel formulation and numerical solution of stochastic inverse problems for physics-based models. The uncertainty is quantified in terms of a probability me...

Groundwater age distributions are used to estimate the parameters of Fickian, and non-Fickian, effective models of solute transport. Based on the similarities between the transport and age equations, we develop a deconvolution based approac...
Importance of Reversible Attachment in Predicting E. Coli Transport in Saturated Aquifers From Column Experiments [0.03%]
关于E. coli在饱水含水层中运移的列管实验中可逆吸附的重要性研究

Drinking water wells indiscriminatingly placed adjacent to fecal contaminated surface water represents a significant but difficult to quantify health risk. Here we seek to understand mechanisms that limit the contamination extent by scaling...
A fractal Richards' equation to capture the non-Boltzmann scaling of water transport in unsaturated media [0.03%]
一个分形Richard方程以捕捉非BoltzmanScaling的非饱和介质中的水分运动
Hongguang Sun,Mark M Meerschaert,Yong Zhang et al.
Hongguang Sun et al.
The traditional Richards' equation implies that the wetting front in unsaturated soil follows Boltzmann scaling, with travel distance growing as the square root of time. This study proposes a fractal Richards' equation (FRE), replacing the ...

Fractional derivatives can be viewed either as handy extensions of classical calculus or, more deeply, as mathematical operators defined by natural phenomena. This follows the view that the diffusion equation is defined as the governing equ...
Averaging Theory for Description of Environmental Problems: What Have We Learned? [0.03%]
平均论在环境问题描述中的应用：我们学到了什么？

This work is the fifth in a series of papers on the thermodynamically constrained averaging theory (TCAT) approach for modeling flow and transport phenomena in multiscale porous medium systems. The general TCAT framework and the mathematica...
TCAT Analysis of Capillary Pressure in Non-equilibrium, Two-fluid-phase, Porous Medium Systems [0.03%]
非平衡两流体相多孔介质体系的毛细压力TCAT分析
William G Gray,Cass T Miller
William G Gray
Standard models of flow of two immiscible fluids in a porous medium make use of an expression for the dependence of capillary pressure on the saturation of a fluid phase. Data to support the mathematical expression is most often obtained th...
