Pricing policies play an important role in water demand management and its optimal allocation. Determining proper water price leads to optimal allocation of water especially in agricultural consumptions. Applying new subsidy targeting law in Iran which insists on pricing water based on its supply cost, will effects considerably on water resource management in agriculture sector. So, in this stu...

abstract irregular extraction from agricultural wells around parishan lake, moreover fall of groundwater surface and water salty, would affect the level of lake water and move lake water into wells. in this study we have evaluated the externalities of extraction from agricultural wells around the lake. therefore feedback effect is considered between agricultural activity around the lake and lev...

background: super oxidized water (sow), as a novel antiseptic solution, is used with claims of effectiveness and cost effectiveness in healing chronic wounds such as diabetic foot, infectious post-operative ulcers and burn ulcers. we conducted a health technology assessment to evaluate the clinical evidence from clinical and randomized trials for this disinfection. this study aims to evaluate t...

the price of water in agriculture plays an important role in the water allocation management. therefore, the optimum strategies of cropping pattern could be designed when water price analysis are considered in a predetermined economic framework. in the present study, a programming model was developed using the genetic algorithm for optimal water allocation in the eastern north of khuzestan prov...

This paper aimed to evaluate Water Use Efficiency (WUE) indices for crops and horticulture productions. In doing so, after gathering data from 164 farmers, we investigated water withdrawal cost indices and monetary return per cubic meter of water through two econometric and managerial approaches . Besides, water shadow pricesand dry matters of per cub meter of water were calculated. The results...

Water quality is a very important issue related to people health, but it is not usually considered in water distribution networks (WDNs) design. In this paper, new constraints such as free residual chlorine and the quality performance index are incorporated into the least cost design of water distribution networks. EPANET2 was applied for the hydraulic and quality analysis of water distributio...

abstract- efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. this research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (wp) with different water management scenarios at farm level at ...
