Interactions between surface and groundwater are a key component of the hydrologic
budget on the watershed scale. Models that honor these interactions are commonly based …

In this paper, we present a class of solvers developed for the parallel solution of Richards'
equation, a model used in variably saturated flow simulations. These solvers take advantage …

Surface flow and subsurface flow constitute a naturally linked hydrologic continuum that has
not traditionally been simulated in an integrated fashion. Recognizing the interactions …

Feedbacks: A Case Study with the WRF-Hydro Coupled Modeling System for West Africa in …

Anyah, RO, CP Weaver, G. Miguez-Macho, Y. Fan, and A. Robock, 2008: Incorporating
water table dynamics in climate modeling: 3. Simulated groundwater influence on coupled …

An automatic time stepping scheme with embedded error control is developed and applied
to the moisture‐based Richards equation. The algorithm is based on the first‐order …

Noniterative implicit time stepping schemes with adaptive temporal truncation error control
are developed for the solution of the pressure form of Richards equation. First‐and second …

Recent work suggests that Anderson acceleration can be used as an accelerator to the fixed-
point iterative method. To improve the viability of the algorithm, we seek to improve its …

We develop a new approach for solving the nonlinear Richards' equation arising in variably
saturated flow modeling. The growing complexity of geometric models for simulation of …

Large-scale, high-resolution hydrologic modeling is an important tool to address questions
of water quantity, availability, and potential recharge. Continental-to-Global scale models …
