Water Footprints and Sustainable Water Allocation

Investigation of Virtual Water and Ecological Footprints of Water in Wheat Fields of Isfahan Province

Despite the recent droughts in Isfahan province, climatic changes and the rising trend of population growth, as well as development of industrial and agricultural activities, are exposed to the water crisis. Thus, in order to tackle this problem, the essential strategies should including exploring virtual water and water foot print for strategic crops in agricultural sector should be taken into...

Optimal Water Allocation: Sustainable Management of Dam Reservoir

Scarcity of water resources and huge costs of establishing new hydraulic installations necessitate optimal exploitation from existing reservoirs. Sustainable management and efficient exploitation from existing finite water resources are important factors in water resource management, particularly in the periods of water insufficiency and in dry regions, and on account of competitive allocations...

Evolving sustainable water networks

The need for efficient pipe networks for urban water supply and drainage is introduced and discussed in the context of global sustainable development. The role of computer based analysis and design tools in the planning and operation of such systems is described, with the way in which these tools can help to minimize use of resources, energy and water losses being explained. In particular, nume...

Global Monthly Water Scarcity: Blue Water Footprints versus Blue Water Availability

Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by c...
