Three different mathematical formulations for the scheduling of pumps to minimize energy consumption while still satisfying operational constraints are presented. Each formulation requires the solution of a highly nonlinear optimization problem that requires the iterative solution of an external numerical model for evaluating and satisfying the operational constraints. Two different algorithms ...

The convergence of networked digital infrastructures and built environments have given rise to the "urban user", a conflation "the user" resident" or citizen". urban user city are mutually constituted phenomena formed through interactions between them. In this research, we contribute an ethnographic study that focuses on everyday water in Pune, India. Using Nikhil Anand's concept "hydraulic cit...

the scarcity of irrigation water and decrease of water resources are the most important limiting factors in crop production in countries such as iran. thus, studying the optimum use of water and increasing water use efficiency are essential to the agricultural sector. the use of a low pressure hydroflume has been suggested to replace traditional surface irrigation methods. the aim of this resea...

This paper explores a variety of strategies for understanding the formation, structure, efficiency, and vulnerability of water distribution networks. Water supply systems are studied as spatially organized networks for which the practical applications of abstract evaluation methods are critically evaluated. Empirical data from benchmark networks are used to study the interplay between network s...

Water distribution systems (WDS) are complex pipe networks with looped and branching topologies that often comprise of thousands to tens of thousands of links and nodes. This work presents a generic framework for improved analysis and management of WDS by partitioning the system into smaller (almost) independent sub-systems with balanced loads and minimal number of interconnection. This paper c...

1. Introduction Water Distribution Systems (WDSs) capable of supplying a sufficient quantity of potable water are one of the key infrastructures for a modern sustainable city. The service quality of WDSs is closely related to water conservation and various detrimental disturbances in WDSs, such as pipe bursts and leaks, will result in significant water loss. World-widely, it is reported that 11...

Most of urban water infrastructure around the world were built several decades ago and nowadays they are deteriorated. So, assets that constitute these infrastructures need to be rehabilitated. Since most buried, utilities face challenge deciding how, where when rehabilitate. Condition assessment is a vital component on plan rehabilitation actions mostly based data collected from managed networ...

a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such as...
