abstract background: the pressure of consumption spots in eater supply systems is one of the most important hydraulic parameters can be used in optimized management of water distribution networks. since the pressure has some different effects on various parameters of the network management including its hydraulic functions, reliability, stability and leakage, its control is of great importance ...

fuzzy water quality index (fwqi) was applied in order to assess the degree of drinking water resources in yazd province, iran. thisstudy has also offered the creation of a new fuzzy water quality index (fwqi) to evaluate this tool’s applicability. 12 chemicalparameters including toxic and non-toxic heavy metals measured in 71 groundwater samples collected from drinking water resourcesin rural a...

“Real Time Sensor Web Enabled Water Quality Monitoring System” is an attempt to develop a general sensor and data model for monitoring water quality. The parameters for determining the quality of water are the pH level, turbidity and temperature. The main aim of this paper is to use a standardized Service Orientated Architecture (SOA), for sensor data representation in universal standards that ...

background: due to the lack of proper rail road and air transportation, most commutes in iran are carried out by buses. in most cases, the water in the busses is used for passengers for drinking usage. although this kind of water source has provided convince for the travelers, it could be a great risk in disease outbreak. the aim of this study is to determine the water quality in commuting buse...

the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...

human activities in the recent years have considerably increased the rate of water pollution in many regions of the world. in this case study, the main sources of wastewater discharging into the gargar river were identified. using river and point source flow rates and water quality parameters measured along the river, the river water quality was simulated using a commonly used, one-dimensional ...

To address water quality standards needed to prevent accelerated eutrophication, many states in the United States have developed effects-based standards related to nutrients. In many cases, this has resulted in specific standards for Secchi transparency (ST) and phytoplankton biomass measured as sestonic chlorophyll (chl-). The state of Arkansas recently adopted its first effects-based water qu...

background: zayandeh-rood river is the only perennial river in the central basin of iran that has fresh water. water from this source is used for drinking, industrial and agricultural purposes. drinking water is extracted from upstream portion (upstream of chamaseman dam) of zayandeh-rood river and therefore its quality is very important. due to growth of population, industry and other factors,...
