Bayesian model averaging on hydraulic conductivity estimation and groundwater head prediction
… and non-uniqueness of parameterization methods. Groundwater predictions are greatly affected by multiple interpretations of aquifer properties and the uncertainties of model parameters. This study introduces a Bayesian model averaging (BMA) method along with multiple generalized parameterization …

Aquifer Compaction at Different Depths: Observations from a Vertical GPS Array at the University of Houston Coastal Center, Texas
… study area. GPS data, precipitation data, and groundwater head measurements were collected at the UHCC for two years (02/2014-02/2016). Ground deformation at 10, 20, 30, and 0 feet below the land surface (bls) were measured from four GPS stations and compared to rainfall and groundwater depth. …

Barrier island groundwater dynamics
… the U.S. Atlantic and Gulf Coasts and coastal groundwater dynamics influence the availability of freshwater, ecosystem health, pollutant transport, and flooding in these densely populated communities. However, groundwater dynamics, including the aquifer head distribution and subsurface salinity …

Bayesian Saltwater Intrusion Prediction and Remediation Design under Uncertainty
Groundwater resources are vital for sustainable economic and demographic developments. Reliable prediction of groundwater head and contaminant transport is necessary for sustainable management of the groundwater resources. However, the groundwater simulation models are subjected to uncertainty in …

Using motes for high resolution hydrological measurement
… soil moisture content, overland flow and groundwater head. The foundation of each cluster was a data box containing a MDA300 data acquisition board and a MICA2 processor board from Crossbow Technologies, Inc.™ that allowed for short range wireless data collection. The 41 motes each …

Evaluating surface water–groundwater interactions in floodplains using SWAT+ and gwflow
… services. Within floodplains, surface water-groundwater exchange plays an important role in facilitating biogeochemical processing and can have a strong influence on hydrology through infiltration or discharge of water. These functions can be difficult to assess due to the heterogeneity of …

Modeling Artificial Groundwater Recharge in the Santa Rosa Creek Watershed
… land and the town of Cambria. Historically the groundwater within the Santa Rosa Creek Watershed has been used for irrigation, municipal and domestic uses, and the creek is critical habitat steelhead trout. During dry years, there is less water for all uses. When low groundwater levels occur, …

Base Flow Recession Analysis for Streamflow and Spring Flow
… when the streamflow at the perennial stream head approaches zero, i.e., flowing streams contract to perennial streams. The identified transition flows are then compared with observed flows when the flowing stream contracts to the perennial stream head. As evidenced by a correlation …

Investigation of Groundwater- Surface-Water Interactions – Application to Leech Lake Aquifer,
… role to ensure sustainable development if both groundwater and surface water can be managed efficiently and equitably through the application of fully integrated systems. This study represents an integrated methodology by using the physically-based surface– subsurface flow model (HydroGeoSphere) …

A combined field analysis and modeling approach for assessing the impact of groundwater pumping on streamflow
… the interactions between stream water and groundwater is also critically important in regions where surface water and tributary groundwater are jointly administered under a prior appropriation doctrine, such as in the western United States. Of particular concern is the effect of a nearby …

Physical and Hydrologic Responses of an Intensively Managed Loblolly Pine Plantation to Forest Harvesting and Site Preparation
… a 20 x 20 m grid of 1-m wells since 1992. Total groundwater heads were determined from differential piezometer measurements at high and low elevation places in each treatment plot. Soil profile descriptions and soil physical property measurements indicated that significant amounts of organic …
