Eastern Truckee Meadows Groundwater Interactions with the Truckee River
… for municipal use. Researching the complex groundwater interactions with the Truckee River will help water managers understand how increased pumping might reduce groundwater seepage to the river, while determining how recharge from injection wells may return flow to the river. The objective …

Monitoring and Imaging Seismic Velocity Changes Across Temporal and Spatial Scales
… the spacetime dv/v observations, I investigate groundwater fluctuations in the Coastal Los Angeles Basins during 2000–2020. The spatial imaging of dv/v reveals pronounced seasonal variability in confined aquifers. The spatial patterns of dv/v are consistent with surface deformation inferred from …

Data-Driven Modeling of the Lake Chad Basin Hydrologic Systems
… affecting river discharge, lake level, and groundwater level fluctuations and to create data-driven models to predict them by using remote sensing climate data. The climate variables employed for this study are air temperature, precipitation, evapotranspiration, soil moisture, soil …

Hydrology of a large unstable hillslope at Ebnit, Vorarlberg : identifying dominating processes and structures
… active areas influences laterally the groundwater reactions of the moving mass. A complex three-dimensional subsurface pressure system is the cause for fast groundwater reactions despite low hydraulic conductivities. To understand hillslope scale variability, hydrotopes representing …

Ground penetrating radar characterization of wood piles and the water table in Back Bay, Boston
… integrity indefinitely. However, recent groundwater fluctuations throughout the Back Bay have exposed the tops of some of the piles, causing the exposed areas to rot. Rotted wood piles weaken a structure's foundation and often result in differential settlement or cracking in walls or …

Evapotranspiration Measurement and Simulation due to Poplar Trees at a Phytoremediation Site
… system and then determining the effect on groundwater flow. This will be accomplished by quantifying evapotranspiration using a water budget, applying White's Equation, comparing groundwater recession curves, creating a groundwater flow model, and examining water table elevations obtained …

Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits
… wetness, often in response to climate-controlled groundwater fluctuations. Tree establishment phases coincide with stratigraphic layers of increased peat humification locally, and periods of increasing temperatures and widespread lake-level lowering regionally in southern Sweden. When conditions …

Determination of irrigation water quality of surface and groundwater in Luvuvhu catchment in Limpopo, South Africa
… activities constitute significant threat to groundwater depletion. This study emphasized on the surface water quality and groundwater quality for irrigation purpose by adopting multivariate statistical methods and the hydrochemical processes and on the probable groundwater contamination in …

Composition and facies variations in mid-cretaceous gates formation coals, Northeastern British Columbia : implications for interpretation of paleo-wetland environments and assessment of coalbed methane characteristics
… in lithotype composition was controlled by groundwater fluctuations and proximity to active fluvial systems. The coals formed on broad, low relief coastal plains, but were rarely subject to marine inundation as sulphur content is consistently low. The vegetation of the Gates mires is …
