Coupled dam-break flow and bed load modelling using HLLC-WAF scheme
A two-dimensional numerical model predicting flow over a mobile bed has been developed. Governing equations consist of the shallow water equations and the Exner equation. The finite volume method on an unstructured triangular grid was deployed to discretize the governing equations. The local Riemann problem is solved by the Harten, Lax and van Leer–contact (HLLC) method in the interface of ...

What does rebounding water use look like? An examination of post-drought and post-flood water end-use demand in Queensland, Australia
Rebounding water use behaviour has been observed in communities that have experienced plentiful water supply following a very dry period. However, the drivers of such rebounds in water consumption are varied and not well understood. Knowledge of such drivers can greatly assist managers towards proactive demand management, modelling and timely promotion of water efficient behaviours. Total and ...

Changes in the water quantity and quality of the Euphrates river are associated with natural aspects of the landscape
It has been argued that dam construction and irrigation projects in Turkey and Syria would diminish the flow of the Euphrates River and increase salinity levels. However, previous studies have not systematically defined the baseline changes in the quantity and quality of the river water. In this study, we associate variations in flow quantity and quality of water with natural aspects. We ...

Case study - Reservoir Aabach Germany - Continuous monitoring of contact pressure
With a total volume of approximately 20 million cubic meters of water and a length of 450 meters, the reservoir supplies drinking water for 200.000 people in the area and fulfils also an important function in the flood protection there. With the new monitoring solution it was possible to reduce the workload and cost for collecting, reading out and transmitting of data significantly. An ...

Water infrastructure security against the current terror threat in the United States
On May 2, 2011, the United States (U.S.) President Barack Obama announced that the U.S. forces killed Osama Bin Laden, the world's most dangerous terrorist leader that killed approximately 3000 Americans on September 11, 2011 (9/11) terror attacks. Currently, the U.S. intelligence is in possession of valuable materials of Al Qaeda operations (Thomas, 2011). Terrorist attack plots include water ...

Comparison of neural networks and neuro-fuzzy computing techniques for prediction of peak breach outflow
Accurate prediction of peak outflows from breached embankment dams is a key parameter in dam risk assessment. In this study, efficient models were developed to predict peak breach outflows utilizing artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS). Historical data from 93 embankment dam failures were used to train and evaluate the applicability of these ...

Dam monitoring in South Africa - Case study
The purpose of the Komati River Basin Development Project is to ensure the availability of water in order to promote economic development in the region. OTT’s part of the project was to supply dataloggers for the monitoring of the river flows into and out of the Maguga and the Driekoppies dams. The technical needs were high-level: Technology designed specifically for environmental ...
