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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Water Industry on the Eco Wave?

A wave of privatization is rolling through the water industry – at the environment‘s expense? In order to provide an answer to this question, the Environmental-Rating agency oekom research AG, Munich, put a number of water supply companies and manufacturers of water appliances to the environmental test. In results published today, oekom identifies the British water supplier Severn Trent as the ...

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% ...

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 ...
