Filtration behaviour of non-woven geotextiles in the gradient ration test
… is established that unifies observations of water head distribution, gradient ratio, permeability of the soil and permeability of the soil-geotextile composite. The unified relationship leads to the identification of three zones that describe the distribution of water head in a gradient ratio …

Experimental investigation on the dynamics of inflatable dams
… Load combinations are considered without any water, with impounding water, and with water overflow. The two major experimental variables are the dam's internal pressure and the stream's flow rate or the impounded water height. The existence of upstream water is shown to completely change the …

Free vibrations of inflatable dams
… rest of the work, the membrane is inflated with water. In some cases there is a reservoir of water on one side of the membrane. The membrane equation of motion is solved using a finite difference method, and the hydrodynamic pressures on the membrane, caused by the motion of the internal and …

Effects of Dissolved Gas Supersaturation and Bubble Formation on Water Treatment Plant Performance
Gas bubbles that form within water treatment plants can disrupt drinking water treatment processes. Bubbles may form whenever the total dissolved gas pressure exceeds the local solution pressure, a condition termed dissolved gas "supersaturation." This project investigated how bubble formation …

Mixing and Attenuation of Upwelling Groundwater Contaminants in the Hyporheic Zone
… zone is the reactive interface between surface water and groundwater found beneath streams and rivers, where chemical gradients and an abundant biological presence allow beneficial attenuation of contaminants. Such attenuation often requires reactants from surface water and groundwater to mix, …
