Background: Qual2k is a stream water quality model and was used to evaluate the water quality of the Kine-Vars River and assess the response of the river to nutrient management strategies. Methods: For that purpose, 7 sample stations were selected and surface water samples were collected in the winter and summer of 2012 and were analyzed for temperature, dissolved oxygen, biological oxygen dem...

water user cooperatives were formed due to consideration to people's empowerment and participation in water investment and management. the purpose of this study was to investigate the mechanisms of development and strengthening of water user cooperatives in the aras river basin. the study population consisted of the management board members of the water user cooperatives in the aras basin in th...

Recent scenario studies on water management focus on one or two projection years and the effects on the water system and functions. The future is however more complex and dynamic. Therefore, we analyse transient scenarios in order to evaluate the performance of water management strategies. Current available simulation tools are not suitable for this purpose. Therefore, we have developed and use...

In modern agriculture, the interplay between complex physical, agricultural, and socioeconomic water use drivers must be fully understood to successfully manage water supplies on extended timescales. This is particularly evident across large portions of the High Plains Aquifer where groundwater levels have declined at unsustainable rates despite improvements in both the efficiency of water use ...

Sustainability of rice production under limited water conditions is threatened by increasing irrigation water scarcity. Therefore, physiological and morphological responses of rice to varying water stress management strategies should be determined. The physiological and morphological responses of a semi dwarf rice (Hashemi cultivar) to water stress intensities (mild and severe, i.e., short-dura...

background : application of strategic management processes at the local level can lead to modeling and development of efficient systems of energy, wastewater, and environmental protection through air pollution prevention. this process is only possible through attention to the strengths, weaknesses, opportunities, and threats of hospitals. this study was conducted with the aim of the presentatio...
