In arid and semi-arid environments, groundwater plays a significant role in the ecosystem. In the last decades, groundwater levels have decreased due to the increasing demand for water, weak irrigation management and soil damage. For the effective management of groundwater, it is important to model and predict fluctuations in groundwater levels. In this study, groundwater table in Kashan plain ...

While the sustainability of resource depletion is a longstanding environmental concern, wider attention has recently been given to growing water scarcity and groundwater depletion. This study seeks to test the substitutability assumption embedded in weak sustainability indicators using a case study of Californian water supply. The volume of groundwater depletion is used as a proxy for unsustain...

Surface water quality can be determined by hydrological responses that vary geographically. The sub-surface hydrologic environment, however, has a primary influence on groundwater movement and hence pollutant migration to the subsurface water. Maps of aquifer vulnerability to pollution are becoming more in demand because on the one hand groundwater represents the main source of drinking water, ...

Cloud computing has emerged as one of the preferred platforms for on-demand, event-driven computing. However, literature on event-driven scientific modeling on the cloud is sparse. This paper presents our vision and architecture to provide a “Scientific Modeling as a Service”in an on-demand fashion. We choose one of the most widely used groundwater models, MODFLOW2000, from USGS to develop a Mo...

abstract water pricing is a policy instrument for improving water efficiency, reducing water demand, management of the irrigation systems and recovering costs. the underlying principle of water pricing is that it should reflect the opportunity cost of water. in this study, parametric mathematical programming approache were used to estimate the willingness of farmers to pay for groundwater under...

Groundwater is increasingly important for satisfying California's growing fresh water demand. Strategies like managed aquifer recharge (MAR) can improve groundwater supplies, mitigating the negative consequences of persistent groundwater overdraft. Distributed stormwater collection (DSC)-MAR projects collect and infiltrate excess hillslope runoff before it reaches a stream, focusing on 40-400 h...

Protection, restoration and development of groundwater supplies and remediation of contaminated aquifers are the driving issues in groundwater resource management. These issues are further triggered on and driven by the population expansion and increasing demands. To transform the ‘vicious circles’ of groundwater availabilities into ‘virtuous circles’ of demands, understanding of the aquifer be...

Safe and reliable access to groundwater is a necessity for people in rural Africa. Many rely on handpumps, for which there is often no system of maintenance in place, leading to around one third being out of use at any given time. Many places are experiencing increased demand for groundwater, leading to the need for a system to monitor groundwater levels. This paper presents a novel approach to...

Groundwater on a small coral island occurs in the form of a lens floating on saline water. The freshwater lens is highly sensitive to various stresses such as pumping, sea tide, etc. Since groundwater is the only source of freshwater on the island, it is not only being utilized for various purposes but also there is growing demand for increased pumpage. In order to assess the impact of addition...
