Study of groundwater using visual MODFLOW in the Manas River Basin, China
For effective groundwater management of a basin, it is essential that a careful water balance study be carried out. A three-dimensional transient-state finite difference groundwater flow model is used to quantify the groundwater fluxes and analyze the dynamic changes of groundwater level. After monitoring groundwater levels for 43 typical observation wells through a simulation study of the ...

The importance of preferential flow in controlling groundwater recharge in tropical Africa and implications for modelling the impact of climate change on groundwater resources
An improved water table fluctuation technique for estimating recharge is applied to a sustained (10-year) groundwater level monitoring record in Uganda, a rare dataset for tropical Africa, and compared against results from soil moisture balance models (SMBMs) and unsaturated flow models. The results show that recharge is directly proportional to rainfall (long-term average rainfall is around 1200 ...

Spatiotemporal groundwater level forecasting and monitoring using a neural network–based approach in a semi arid zone
Forecasting the groundwater level (GWL) of an aquifer is one of the most important tasks in hydrogeology. Such forecasts prove vital to develop better exploitation strategies of water resources and to carry up–to–date groundwater monitoring. In this paper, an artificial neural network (ANN)–based approach, which was based on linear regression model, is presented to simulate and predict both ...

Westbay System Reduces Construction Costs by 65% - Case study
CHALLENGE OCWD had determined that information on the piezometric level and water quality of each aquifer layer was required to optimize management of the recharge, storage, and recovery of groundwater. SOLUTION A cost analysis indicated that for 10 zones through a depth of 1,500 ft, the Westbay System instrumentation would result in a total cost 55% to 65% lower than that for clustered wells or ...

Water resources in Korisos basin, NW Greece: interactions between surface and ground water
The aim of this paper is to review the water resources of the Korisos basin located in the NW Greece and to explore the ground- and surface water interactions. Based on results, it can be concluded that there is a hydraulic communication between the torrent flow and the alluvial aquifer, indicating the important role of stream flow to recharge the alluvial aquifer. Total abstraction from the ...

Geostatistics-based spatial variation characteristics of groundwater levels in a wastewater irrigation area, northern China
Although wastewater reuse in agriculture can ease water scarcity, this practice also alters the variation of groundwater recharge and groundwater levels. This study employed a geostatistical method to systematically investigate the spatio-temporal variations and storage fluctuations of groundwater in a wastewater irrigation area in a southeastern suburb of Beijing. Specifically, we generated ...

Spatio-temporal assessment of groundwater level and quality in urban coastal city Puri, India
Puri city is situated on the shoreline of Bay of Bengal and groundwater is the only source available to meet the city water supply mainly from two demarcated water fields. Due to the anthropogenic activities and absence of sewerage system, groundwater quality is deteriorating through open discharges of domestic waste, open defecation, septic tanks, soak pits, contaminated water pools, unorganized ...

Regional Ground Water Level Monitoring in Germany
Reference Project: Regional Ground Water Level Monitoring, Germany ribeka is responsible for monitoring the ground water levels within an area of over 4.000 km2 in the western German province of North Rhine-Westphalia. Within this densely populated area that comprises many large cities (e.g. Cologne and Bonn) as well as Europe’s biggest brown coal open mining site, extensive ground water ...

GW monitoring in saxony
Background During the hundred-year flood in 2002 in Eastern Germany the river “Elbe“ and a lot of rivers in the catchment area exceeded the banks and caused damages of millions within a short period of time. Often unnoticed, the groundwater level was rising extremely after a certain time. The time of rising groundwater took considerably longer than the actual flood, and caused enormous ...

Report documents effects of 40 years of groundwater withdrawal
The cumulative effects of 40 years of groundwater withdrawals in the Houston-Galveston region are documented in a report from the United States Geological Survey. Decades of extensive withdrawals have caused the land to sink, or subside. The Houston-Galveston region is one of the largest areas of land surface subsidence in the U.S., according to the agency. Water withdrawals started as early as ...
