compared to conventional chlorination methods which apply chlorine at water treatment plant, booster chlorination has almost solved the problems of high dosages of chlorine residuals near water sources and lack of chlorine residuals in the remote points of a water distribution system (wds). however, control of trihalomethane (thm) formation as a potentially carcinogenic disinfection by-product ...

This study presents a multimodal hub location problem which has the capability to split commodities by limited-capacity hubs and transportation systems, based on the assumption that demands are stochastic for multi-commodity network flows. In the real world cases, demands are random over the planning horizon and those which are partially fulfilled, are lost. Thus, the present study handles dema...

The lack of water resources in Iran has increased concern about water consumption in the country. The agricultural sector is known as the largest sector of water consumption, and saving in this sector will save significant water resources. One of the solutions for the optimal use of water resources is the use of modern irrigation methods with proper design and implementation. Therefore, the pur...

administrative regulations for water flow decrease distribution efficiency and effect the economical operation of irrigation networks. complications in distribution systems and the decrease in availability of water require study of the hydraulic performance of existing flow control structures. control systems designed by neyrpic (zayandeh rud network) and usbr (doroodzan network) were investiga...

Given the large contribution of government investment in the economy of Iran through spending on infrastructure budgets,resources distribution among the provinces was always one of the major problems in the economy. Distribution of budget among provinces theoriticalyis based on tactical and/or programmatic approach. In tactical approach, redistributive policyof the central government is based o...

Households around the world access water through an intermittent piped water supply; however, delivery of water in these systems is often unpredictable, creating a burden for households waiting to collect water and utilities managing its distribution. We present NextDrop, a system that allows water operators to report information through existing networks of mobile phones and use that informati...
