Prediction of Sediment Transport Capacity in Rivers Using Quasi Two-Dimensional Mathematical Model

Sediment rating curve is an essential factor for many river engineering subjects and computations such as dredging, design of storage dams, river intakes design and sand mining management. Although, this curve is established using simultaneous measurement of flow and sediment transport discharges, however, due to lack of reliable data during flood events, it has limited reliability in flood con...

an application of positive mathematical programming model to analyze the effects of alternative policies to water pricing in mashhad plain

abstract management of water resources in iran is faced with growing demand for water resources, a considerable increase in the costs of supplying additional water and uncontrolled exploitation of underground waters. economists suggest water pricing to improve water use efficiency; however, government tends to reject that advice due to political risk, economic and cultural concerns. we used a p...

An Extended Mathematical Programming Model to Optimize the Cable Trench Route of Power Transmission in a Metro Depot

The necessary electricity of the workshops and buildings (W&Bs;) located at the metro depot are provided by lighting power substation (LPS). To transmit electricity between LPS and W&Bs;, some trenches should be dig and the requisite cables should be located in the trenches. This paper presents a new mixed integer linear programming (MILP) long-term decision model to find ...
