Water network performance is defined as the ability to deliver a required quantity of water under sufficient pressure and an acceptable level of quality. A sound performance indicator is a powerful tool for more efficient ...

A new approach to modeling injecting domainhas been developed based on changing permeability coefficient in a certain form in theory of consolidation. The proposed model utilizes the variation of the coefficient of ...

The dynamic interaction of fluid-solid systems has long been a subject of interest in many engineering fields. One of the most important problems of this nature, encountered in civil engineering, is the dynamic interaction ...

In this paper, ant colony optimization (ACO) algorithms are proposed for reservoir operation. Through a collection of cooperative agents called ants, the near optimum solution to the reservoir operation can be effectively ...

In this paper, based on the free vortex theorem and the momentum equation, a theoretical model to predict the pressure head distribution, the pressure coefficient, the end depth ratio (EDR), and flow discharge at the brink ...

The main characteristic of the flow induced by groynes is the development of a recirculating flow area. An interaction between the recirculating flow and bed mobility leads to the development of a scour hole around the ...

The implementation of boundary conditions in sub-critical and supercritical flow is quite different when using characteristics leading to programming difficulties with the associated numerical schemes. For supercritical ...

In this paper, a genetic algorithm (GA) method is employed to determine the location of the critical non-circular slip surface giving the minimum factor of safety in conjunction with the magnitude of interslice forces and ...

Use of fiber reinforced plastic (FRP) composites for strengthening of beams and columns in RC structures has attracted great attention in recent decades. However, less attention has been paid to strengthening RC connections ...
