Water scarcity is one of the main concerns of several countries around the world. In this context, several approaches have been proposed for resource conservation and available water augmentation through specific actions such as process intensification and the use, reclamation, reuse, and recycle of alternative water sources. Nonetheless, there are no reported methodologies optimizing the multi...

The piped water consumption per capita is more than 142 cubic meters per year in Iran that is higher than the consumption per capita of some water-filled European countries such as Belgium and Austria. The use of drinking water for washing dishes, clothes, cars as well as bathing and watering gardens are of the important reasons for piped water high consumption in Iran. However, different lifes...

Population growth, growing scarcity of freshwater resources and food security have convinced all operators that spending large sums of money on cross-cutting responses to water, energy and food needs, especially in the face of climate change and global warming, is unreasonable.According to the latest classification of the International Geographical Organization, Iran is located in the category ...

The presence of human norovirus in the aquatic environment can cause outbreaks related to recreational activities and the consumption of norovirus-contaminated clams. In this study, we investigated the prevalence of norovirus genogroups I (GI) and II (GII) in the coastal aquatic environment in South Korea (March 2014 to February 2015). A total of 504 water samples were collected periodically fr...

Furrow irrigation is the most common method of surface irrigation. However, the accurate estimation of the soil water infiltration equation is the most important challenge for evaluating this method of irrigation. In this study, a fast and simple method that is named soil intake families and presented by USDA-NRCS (RSIF), evaluated for estimation of the Kostiakove-lewis infiltration equation pa...
