One-Step Reverse Osmosis Based on Riverbank Filtration for Future Drinking Water Purification

The presence of newly emerging pollutants in the aquatic environment poses great challenges for drinking water treatment plants. Due to their low concentrations and unknown characteristics, emerging pollutants cannot be efficiently removed by conventional water treatment processes, making technically, economically, and environmentally...

Groyne field nourishments: A research into the application of feeder nourishments to supply sediment to the main channel

In the Waal bed degradation occurs, which is mainly induced by a large number of river regulations measures done in the past. Rijkswaterstaat develops possible measures and new techniques to stop riverbed erosion and/or mitigate the negative effects. One of the possible new techniques to reduce riverbed erosion locally is groyne field...

Drivers for mass and momentum exchange between the main channel and river bank lateral cavities

Large-Eddy Simulations (LES) are used to investigate the governing processes involved in mass and momentum transfer between the flow in the main channel and symmetrically-distributed lateral bank cavities. In-cavity free-surface velocities, based on laboratory measurements made in an open channel, are used to validate the numerical results. A...

Problems and promise of managed recharge in karstified aquifers: the example of Lebanon

Managed aquifer recharge can store surface water as safe and reliable groundwater for later recovery. However, most options are problematic in karstic aquifers due to complex hydrodynamics reducing their effectiveness and hence general applicability. River bank filtration and urban stormwater infiltration systems are among the main managed...

Organic micropollutant removal during river bank filtration

This study investigated the factors influencing the main removal mechanisms (adsorption and biodegradation) for organic micropollutant (OMP) removal during river bank filtration (RBF) and the possibility of developing a predictive model of this process for OMP removal during RBF. Chapter 2 analysed the sorption and biodegradation behaviour of 14...

Transformation of organic micropollutants during river bank filtration: Laboratory versus field data

This paper investigates the degradation behavior of 14 organic micropoliutants (OMPs), selected for their different physico-chemical properties (e.g., molecular weight, hydrophobicity and charge). In soil columns simulating the conditions prevailing in the first meter of river bank filtration (RBF) media. The results from the column system are...

Bank erosion prediction and mitigation measures along the lower Mekong river

The Lower Mekong River area is a zone with plenty of natural resources and it has the highest agricultural production in Vietnam. The river passes though six provinces in the Southern patt of Vietnam, with more than 16 million in habitants in total. However, serious riverbank erosion problems occur and there is no master plan or mitigation...

Evaluation and recommendations for river bank protection at Faridpur District Town - Padma River

River bank erosion and bank protection review - Chandpur Town, lower Mehna

A mision to investigate morphological problems around the city of Chandpur, concluded that the recent slide in the Dakatia River underlines the serious dangers threatening Chandpur in this period. Unless major action is taken at short notice there is a large risk that other parts of Chandpur Town Protection will fail as well with dire...

Morphological Changes due to River Bank Protection

When bank protection works are constructed along an eroding outer bank, it is often observed that the bed along the outer bank becomes substantially deeper, sometimes causing the failure of the bank protection works themselves. Despite our awareness of this deepening phenomenon, its causes and quantitative estimation is still a matter of...
