Characterizing Stream-Aquifer Interactions in the Pedernales Watershed in Central Texas
Understanding the nature of stream-aquifer interaction is important for understanding the degree of hydraulic connection between streams and adjacent aquifers within any given watershed. Such information is necessary before the effects of groundwater pumping on streamflow, or the effects of …

Field Investigation of Stream-Aquifer Interactions: A Case Study in Coastal California
… of the dynamic interaction between a stream and an alluvial aquifer at Swanton Pacific Ranch in the Scotts Creek watershed in Santa Cruz County, California. The aquifer is an important source of groundwater for cropland irrigation and for aquatic ecosystem support. The potential for …

Modeling nonpoint-source uranium pollution in an irrigated stream-aquifer system: calibration and simulation
… numerical model for assessing U pollution in a stream-aquifer system within a large irrigated area. To achieve this, a computational model is built and tested that can predict with reasonable accuracy how U, along with Se and NO3, are mobilized and move within a coupled system of streams and …

Development of a model for simulation of solute transport in a stream aquifer system
A model for simulation of solute transport in a stream-aquifer system is developed. The model is referred to as: Model for Stream-Aquifer Solute Transport or MSAST. The MSAST is developed by coupling four primary models: The groundwater flow model, MODFLOW-96, the coupled groundwater surface water …

Arsenic transport in groundwater, surface water, and the hyporheic zone of a mine-influenced stream-aquifer system
… surface water and the hyporheic zone in a stream-aquifer system influenced by an abandoned arsenopyrite mine. Mine tailing piles consisting of a host of arsenic-bearing minerals including arsenopyrite and scorodite remain adjacent to the stream and represent a continuous source of arsenic. …

A spatial decision support system for basin scale assessment of improved management of water quantity and quality in stream-aquifer systems
… groundwater models for basin-scale modeling of stream-aquifer interactions. The core River GeoDSS is customized to provide comprehensive analysis of alternative solutions to achieving agricultural, environmental, and water savings goals in the Lower Arkansas River Basin in Colorado while …

Flood Processes in Semi-arid Streams: Sediment Transport, Flood Routing, and Groundwater - Surface Water Interactions
Flooding in semi-arid streams is highly variable but distinguished from its humid counterpart in terms of forcing conditions, landscape response, flood severity, and stream-aquifer connectivity. These floods have the potential for great benefit in a water-limited environment, but also great …

A combined field analysis and modeling approach for assessing the impact of groundwater pumping on streamflow
… magnitude of volumetric water exchange between streams and alluvial aquifers impacts contaminant transport rates, channel erosion and sedimentation, nutrient loading, and aquatic and riparian habitat. Quantifying the interactions between stream water and groundwater is also critically important …

Mathematical Modeling of the Movement of Heat, Water, and Solutes in Two-Dimensional, Saturated-Unsaturated, Surface Water - Groundwater Flow Systems
… for estimating recharge and discharge between streams and alluvial aquifers, and for studying the behavior of pollutants during infiltration of polluted surface water to groundwater. A two-dimensional, cross-sectional, saturated-unsaturated, finite difference model for simulating the movement …

Analyzing and modelling of flow transmission processes in river-systems with a focus on semi-arid conditions
… Three different sources of hydrological data (streamflow series, groundwater level series and multi-temporal satellite data) were combined in order to analyze the channel transmission losses of a large reach of the Jaguaribe River in NE Brazil. A perceptual model of this reach was derived …

Spatial dynamic groundwater regulation to ensure adequate instream flows for salmon
… quantities of water for fish species in nearby streams. Groundwater pumping can lead to a reduction in instream flows of nearby streams in a process known as stream depletion. From an economic standpoint, policies intended to leave adequate quantities of water instream for any purpose should aim …
