water quality in each area, indicates the impact of geology, climate and anthropogenic pollutants. monitoring of water quality in most cases result in complex data which shows the perfect act of water resources, so they need appropriate method for analyzing. in this study hydro-chemical evaluation of hiv basin which located in west of hashtgerd have been done. to measure the concentration of ma...

The Water Observation and Information System (WOIS) is an open source software tool for monitoring, assessing and inventorying water resources in a cost-effective manner using Earth Observation (EO) data. The WOIS has been developed by, among others, the authors of this paper under the TIGER-NET project, which is a major component of the TIGER initiative of the European Space Agency (ESA) and w...

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...

Abstract The main idea of this article is to adopt the thesis that and, at same time, most effective (apart from proper maintenance and operation) element strategy limiting water losses in supply networks continuous integrated monitoring network using latest achievements IT technologies, including GIS (Geographical Information System), GPS (Global Positioning GSM (The Global System for Mobile C...

The main goal of this large-scale pilot distribution study was to systematically investigate the impacts of blending different source waters on distribution water qualities. The principal source waters investigated were conventionally treated ground water (G1), surface water processed by enhanced treatment (S1), and desalted seawater by reverse osmosis membranes (RO). Due to the nature of raw w...

Large public water utilities currently are required to take several 100 mL water samples every month in their distribution systems and to test these samples for the presence of total coliforms to comply with the Total Coliform Rule. How and where they take these samples is not specified. The Total Coliform Rule is currently undergoing review and revision. One possible revision is more specific ...

Water quality information is important for guiding water safety management and preventing water-related diseases. To assess the current status of regulated water quality monitoring in sub-Saharan Africa, we evaluated testing programs for fecal contamination in 72 institutions (water suppliers and public health agencies) across 10 countries. Data were collected through written surveys, in-person...

College of Information and Electrical Engineering, China Agricultural University, Beijing, China Abstract. This paper presents a system framework taking the advantages of the WSN for the real-time monitoring on the water quality in aquaculture. We design the structure of the wireless sensor network to collect and continuously transmit data to the monitoring software. Then we accomplish the conf...
