Optimal design of groundwater-level monitoring networks
Groundwater monitoring plays a significant role in groundwater management. This study presents an optimization method for designing groundwater-level monitoring networks. The proposed design method was used in the Eshtehard aquifer, in central Iran. Three scenarios were considered to optimize the locations of the observation wells: (1) designing new monitoring networks, (2) redesigning ...

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 ...

Stochastic simulation of groundwater dynamics based on grey theory and seasonal decomposition model in a coastal aquifer of South China
Accurate and reliable prediction of groundwater level is a critical component in coastal water management. It is important to find a suitable model with acceptable accuracy. This paper presents a comparative study with seasonal decomposition method of time series analysis and GM (1,1) method, which are applied to test the model accuracy by simulating groundwater levels of two representative ...

Why You Should Monitor Groundwater?
What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it reaches and ...

Texas Drought Notification System Monitors Groundwater Levels, Spring Flow to Trigger Action
Conservation districts are looking for better ways to monitor and manage water resources, which are affected by naturally occurring cycles of drought, rising populations, and increasing demands from industrial sectors. Climate change associated with increased levels of greenhouse gases in the atmosphere may increase severity of future droughts (IPCC 2007). Potential effects of global climate ...

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 ...

Wesleyan University Students Research Aquifer Recharge with Water Level Monitoring
Overview Wesleyan hydrology students used the Level TROLL 700 to monitor groundwater levels and perform slug tests to understand how climate change may impact aquifer recharge in the northeastern U.S. Challenge Students wanted to explore how climate change might impact groundwater levels in the Northeast, where precipitation is becoming less frequent but more intense. Increased rainfall ...

Self-organizing map clustering technique for ANN-based spatiotemporal modeling of groundwater quality parameters
The present study integrates co-kriging as spatial estimator and self-organizing map (SOM) as clustering technique to identify spatially homogeneous clusters of groundwater quality data and to choose the most effective input data for feed-forward neural network (FFNN) model to simulate electrical conductivity (EC) and total dissolved solids (TDS) of groundwater. The methodology is presented ...

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 ...
