Simulation and uncertainty analysis for groundwater levels using radial basis function neural network and support vector machine models
Accurate measurement of groundwater levels is often difficult and involves great uncertainty. Therefore, simulating and predicting the fluctuating behavior of groundwater levels is necessary for water resource planning and management. In this study, radial basis function (RBF) neural networks and support vector machines (SVM) were employed to simulate groundwater level fluctuations. The time ...

Wavelet analysis–artificial neural network conjunction models for multi-scale monthly groundwater level predicting in an arid inland river basin, northwestern China
In this study, the ability of a wavelet analysis–artificial neural network (WA-ANN) conjunction model for multi-scale monthly groundwater level forecasting was evaluated in an arid inland river basin, northwestern China. The WA-ANN models were obtained by combining discrete wavelet transformation with ANN. For WA-ANN model, three different input combinations were trialed in order to optimize ...

From 6 Belgian knights to groundwater monitoring - Case Study
Project From 6 Belgian knights to groundwater monitoring. Opdrachtgever Affligem Brewery Land Belgium Background to installing the monitoring network Pieter Careel, Production Support Coordinator, at Affligem Brewery: "The government is very careful about issuing environmental permits for pumping groundwater. We must be able to demonstrate that we use the water for high technology ...

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 ...

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 ...

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 ...
