A new numerical method was developed to accurately and efficiently compute a solution of
the nonlinear Richards equation with a layered soil. In the proposed method, the Kirchhoff …

The CPqPy framework coupling COMSOL and PHREEQC based on Python was developed.
This framework can achieve the simulation of diversified situations including multi‐physics …

Robust and reliable numerical models are vital to solve the Richards' equation, which
depicts the variably saturated flows in porous media. In this study, the Richards' equation is …

The hydrodynamic processes and impacts exerted by river-groundwater transformation
need to be studied at regional and catchment scale, especially with respect to diverse …

近年来有限分析法被广泛应用于模拟土壤水分运移. 混合型有限分析法通常使用一阶有限差分
近似代替Richards 方程中的时间导数项. 然而, 这种处理方式可能会引起数值弥散 …

A new finite analytic method (FAM) was proposed to obtain a stable and accurate solution of
highly nonlinear Richards' equation (RE) for simulating flow through heterogeneous soils …

In this work, we incorporate the solution of Richards equation in infinite slope model to
locate the potential landslide hazards area and prediction of landslide hazards induced by …

Convection-diffusion equation is widely used to describe many engineering and physical
problems. The finite element method is one of the most common tools for computing …

An accurate polynomial solution is worked out for the general Gardner-based infiltration
equation for a heterogeneous soil column with the sink term of the equation being treated as …
