Integrated surface–groundwater flow modeling: A free-surface overland flow boundary condition in a parallel groundwater flow model
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 on the conductance concept that presumes a distinct interface at the land surface, separating the surface from the subsurface domain. These types of models link the subsurface and surface domains via an exchange flux that depen...
متن کاملInfluence of lateral subsurface flow and connectivity on soil water storage in land surface modeling
Lateral surface/subsurface flow and their connectivity play a significant role in redistributing soil water, which has a direct effect on biological, chemical, and geomorphological processes in the root zone (~1m). However, most of the land surface models neglect the horizontal exchanges of water at the grid or subgrid scales, focusing only on the vertical exchanges of water as one-dimensional ...
متن کاملEffects of Soil Moisture Heterogeneity on Boundary Layer Flow with Coupled Groundwater, Land-surface, and Mesoscale Atmospheric Modeling
Mesoscale atmospheric models currently rely on an integrated land-surface model to provide fluxes of heat, momentum, and moisture from the land surface to the atmosphere. While improvements have been made by tuning land-surface models for a variety of test cases, current models are limited to vertical transport in a shallow soil column. They are thus unable to capture lateral transport of soil ...
متن کاملIncorporation of groundwater pumping in a global Land Surface Model with the representation of human impacts
Observations indicate that groundwater levels are declining in many regions around the world. Simulating such depletion of groundwater at the global scale still remains a challenge because most global Land Surface Models (LSMs) lack the physical representation of groundwater dynamics in general and well pumping in particular. Here we present an integrated hydrologic model, which explicitly simu...
متن کاملGlobal-scale modeling of groundwater recharge
Long-term average groundwater recharge, which is equivalent to renewable groundwater resources, is the major limiting factor for the sustainable use of groundwater. Compared to surface water resources, groundwater resources are more protected from pollution, and their use is less restricted by seasonal and inter-annual flow variations. To support water management in a globalized world, it is ne...
