Chunnakam and Vadamaradchi are two major aquifer systems in Jaffna Peninsula, Sri Lanka. This study was performed to compare water quality in the domestic wells in these aquifers and to assess the efficacy of household water treatments for treating contaminated water. Replicate well water samples were collected from each aquifer and pH, dissolved oxygen (DO), conductivity, total dissolved solid...

Abstract Constraints on water resources and increasing the number and variety of water users has led to appeal of the importance of optimal water allocation. The Khanmirza watershed in Chaharmahal Va Bakhtiari Province, has experienced unsustainable development by relying on groundwater resources.  As a result of this imbalance, a dramatic drop occurred in the aquifer of the Khanmiza plain. Th...

Limitations of rainfall and surface water resources farmers have to use both surface and subsurface resources for growing different crops. In this study optimal management of irrigation water allocation and cropping pattern utilizing conjunctive use of surface and subsurface water resources is studied. Also the effect of reducing water consumption in different growth stages with different irrig...

Journal: Iranian Economic Review 2019

The imbalance between water supply and demand in the country has challenged water resource management, especially in the agricultural sector. The virtual water study approach, as an approach that values the use of water inputs in the production and consumption of various commodities, has been established and discussed for almost two decades. Based on this concept, the issue of virtual water tra...

[1] In this work we demonstrate that the combination of agent-based modeling and simulation constitutes a useful methodological approach to dealing with the complexity derived from multiple factors with influence in the domestic water management in emergent metropolitan areas. In particular, we adapt and integrate different social submodels, models of urban dynamics, water consumption, and tech...
