evaluation of surface water quality is a complex process undertakingmultiple parameters. converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.the main aim of this study is to plan effective water resources management system forkarun river by combination of ccmewqi and geographic information system ...

Cyber attacks are an emerging threat to critical infrastructure systems worldwide. We focus on water, recognizing that water is vital for human health and to the function of other critical infrastructures. A cyber attack targets control and monitoring systems of a water utility, known as supervisory control and data acquisition (SCADA) systems, and disrupts water operations. Current research is...

The availability of freshwater is one the biggest limitations and challenges food production, as an increasingly scarce overexploited resource in many parts world. Therefore, concept water footprint (WF) has gained increasing interest, same way that generation loss waste (FLW) production consumption become a social political concern. Along this line, number studies on WF sector currently all ov...

Yield stability is fundamental to global food security in the face of climate change, and better strategies are needed for buffering crop yields against increased weather variability. Regional- scale analyses of yield stability can support robust inferences about buffering strategies for widely-grown staple crops, but have not been accomplished. We present a novel analytical approach, synthesiz...
