Density-driven interstitial water motion in sediments

Water wave-driven seepage in marine sediments

The action of water waves moving over a porous seabed drives a seepage ̄ux into and out of the marine sediments. The volume of ̄uid exchange per wave cycle may a€ect the rate of contaminant transport in the sediments. In this paper, the dynamic response of the seabed to ocean waves is treated analytically on the basis of poro-elastic theory applied to a porous seabed. The seabed is modelled as ...

Currents in Stratified Water Bodies 1: Density-Driven Flows

Head-Driven Simulation of Water Supply Networks

Up to now most of the existing water supply network analyses have been based on demand-driven simulation models. These models assume that nodal outflows are fixed and are always available. However, this method of simulation neglects the pressure-dependent nature of demand that is characterized by changes in actual nodal outflows particularly during critical events like major mechanical or hydra...

Forecasting Ozone Density in Tehran Air Using a Smart Data-Driven Approach

Introduction: As a metropolitan area in Iran, Tehran is exposed to damage from air pollution due to its large population and pollutants from various sources. Accordingly, research on damage induced by air pollution in this city seems necessary. The main purpose of this study was to forecast ozone in the city of Tehran. Considering the hazards of ozone (O3) gas on human health and the environmen...

Value-Driven Code Motion

Value-driven code motion is an improvement to classical code motion techniques that takes advantage of the results of global value numbering. Traditional data-ow analysis frameworks must assume that every deenition produces a distinct value. Therefore, an instruction cannot move past a deenition of one of its subexpressions. This restriction can be relaxed when certain deenitions are known to p...
