Abstract: Coupling of two-phase flow with mechanical deformation has important applications in many fields, including dense nonaqueous phase liquid (DNAPL)–water transportation through the subsurface. To understand and couple the ...

Abstract: In this paper we are presenting a numerical model to simulate transient flow and solute transport through a variably saturated zone. The mixed form of the Richards equation is used for the solution of the flow component ...

Abstract: The maintenance of chlorine residual is needed at all the points in the distribution system supplied with chlorine as a disinfectant. The propagation and level of chlorine in a distribution system is affected by both bulk ...

Abstract: The specified range of free chlorine residual (between minimum and maximum) in water distribution systems needs to be maintained to avoid deterioration of the microbial quality of water, control taste and/or odor problems, ...

Abstract: It is a well-known fact that most of the developing countries have intermittent water supply and the quantity of water supplied from the source is also not distributed equitably among the consumers. Aged pipelines, pump ...

Abstract: A study is made of transients in canal networks using a mathematical model based on St. Venant equations. The transient effects of different combinations of types, location, and operation of control structures are studied. ...

Abstract: An integrated approach in the control of flow and quality in water distribution systems has been proposed. Simultaneous proportional integrated derivative (SIM-PID) and normalized proportional integrated derivative (NOM-PID) ...
