Since “Groundwater and Surface Water–A Single Resource”: some U.S. Geological Survey advances in modeling groundwater/surface-water interactions

Modeling surface water-groundwater interaction with MODFLOW: some considerations.

The accuracy with which MODFLOW simulates surface water-groundwater interaction is examined for connected and disconnected losing streams. We compare the effect of different vertical and horizontal discretization within MODFLOW and also compare MODFLOW simulations with those produced by HydroGeoSphere. HydroGeoSphere is able to simulate both saturated and unsaturated flow, as well as surface wa...

Measuring groundwater-surface water interactions: a review

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Interactions between groundwater and surface water play a critical role in the functioning of riparian ecosystems. In the context of sustainable river basin management it is crucial to understand and quantify exchange processes between gro...

Measuring methods for groundwater – surface water interactions: a review

Interactions between groundwater and surface water play a fundamental role in the functioning of riparian ecosystems. In the context of sustainable river basin management it is crucial to understand and quantify exchange processes between groundwater and surface water. Numerous well-known methods exist for parameter estimation and process identification in aquifers and surface waters. Only in r...

Coastal Groundwater Management with Nearshore Resource Interactions

This paper develops a regional hydrologic-ecologic-economic model of groundwater use and a nearshore ecosystem. Particularly, we model coastal groundwater management and its effects on discharge, nearshore water quality, and marine biota (e.g., indigenous marine algae). We show that incorporating the external effects on nearshore resources increases the optimal steady-state head level. Numerica...
