Simulation of Groundwater Level in Ephemeral Streams with an Improved Groundwater Hydraulics Model
Groundwater, 2019Abstract As a component of arid ecosystems, groundwater plays an important role in plant growth; therefore, it is essential to use deterministic models to reconstruct the process of groundwater level change. Typically, the linearized solution of the one‐dimensional (1‐D) Boussinesq equation yields acceptable ...

Water-level changes in wells during and after earthquakes have been reported since the time of antiquity (e.g., Institute of Geophysics – CAS, 1976) and are the most widely documented changes among all earthquake-induced hydrologic phenomena. Since the early twentieth century, instrumental records of water-level changes during earthquakes have become ...

Rising groundwater levels in cities
Geological Society, London, Engineering Geology Special Publications, 1986Abstract It is well documented that groundwater levels in a number of cities in this country and abroad have been rising over the past few years. Parts of central London are experiencing rises of one metre per year, while in Paris, previously dry basements are now affected by severe flooding.

Sea Level Rise and Groundwater
2021Rising sea levels pose a direct threat to coastal communities through permanent inundation of low-elevation areas and greater and more widespread temporary inundation from possibly more intense storms and king tides atop a higher sea level baseline.

Groundwater Level Monitoring Tests with Seismic Interferometry
NSG2020 26th European Meeting of Environmental and Engineering Geophysics, 2020Summary The objective of this work is to evaluate whether the seismic passive interferometry technique can be used to monitor undeground water variations in both unconfined and confined aquifers that present different hydrogeological characteristics. We collected ambient vibrations in two different water catchment fields where the water level has been ...

Declining groundwater levels in India
International Journal of Water Resources Development, 1989The decline of groundwater levels in India by 5–10 m is usually explained as a result of the increased number of tubewells and a decline in average annual rainfall. This article argues that the decline is the product of the destruction of indigenous systems for storing runoff water, which are essential because rainy days are very few and erratic ...

Why is the Groundwater Level Rising? A Case Study Using HARTT to Simulate Groundwater Level Dynamic
Water Environment Research, 2017ABSTRACT: Groundwater from a shallow unconfined aquifer at a site in coastal New South Wales has been causing recent water logging issues. A trend of rising groundwater level has been anecdotally observed over the last 10 years. It was not clear whether the changes in groundwater levels were solely natural variations within the groundwater system or ...

Fluoride levels in Texas groundwater
Journal of Environmental Science and Health, Part A, 1999Abstract The purpose of this study was to compile, map, and evaluate regional patterns of fluoride concentrations in Texas groundwater. County‐median fluoride levels were calculated from nearly 7,000 wells distributed among 237 Texas counties. Four regions having high fluoride levels were identified. These regions occupy parts of west, southwest, north‐
