Groundwater function zoning is an important means to ensure that groundwater plays its various functions, which can provide a scientific basis for the protection and development of resources. Water resources are scarce in Central Plains Urban Agglomeration (CPUA), so it great significance evaluate vulnerability zone this area. In study, resource supply (RSF), eco-environment (EEF), geo-environm...

Joint assessment of groundwater-surface water resources can help develop sustainable regional water management plans for intensive agriculture. In this study, we estimated allowable groundwater and surface water quantities using a water balance model, WetSpass-GMS, for the Sanjiang Plain (10.9 × 104 km2), one of the most important grain production bases in China. We then applied a double contro...

Water resources of a country constitute one of its vital assets. India receives annual precipitation of about 4000 km. The rainfall in India shows very high spatial and temporal variability and paradox of the situation is that Mousinram near Cherrapunji, which receives the highest rainfall in the world, also suffers from a shortage of water during the non-rainy season, almost every year. The to...

Groundwater level prediction in a water basin plays a significant role in the management of groundwater resources. Aground water level forecasting system is developed in this study using Support vector Machines (SVM). Further Quantum behaved Particle Swarm Optimization (QPSO) function is employed in this study to determine the SVM parameters. Later, the proposed SVM-QPSO model is used in determ...

The US National Assessment of the Potential Consequences of Climate Variability and Change provides compelling arguments for serious consideration of actions and adaptive measures by countries around the world to better manage impacts on water resources, agricultural economic sustainability and environmental quality. National resource planning at this scale requires integrated impact analysis t...

in developing and newly industrialized countries, population growth and migration contribute immensely to the development of megacities and mega urban areas. in most cases, the rapid development ofcities has far-reaching consequences for the ecosystem in general and the hydrological cycle in particular. the developments in china within the last decades show an interesting, but complex setting. ...

Groundwater recharge must be well understood for the effective utilization of water resources. In this article some of the recent studies in groundwater recharge modeling are detailed and discussed. The topics covered include (1) Recharge modeling in deterministic framework, (2)Recharge modeling in stochastic framework, (3) Recharge modeling using electromagnetic surveys (4) Mountain front rech...

Shallow hand-dug wells are commonly used to supplement partial or intermittent piped water coverage in many urban informal settlements in sub-Saharan Africa. Such wells are often microbially contaminated. This study aimed to quantify the amount of such groundwater consumed, identify the socioeconomic profile of well owners and consumers, and patterns of domestic water usage in informal settleme...

Groundwater resources make up an important portion of potable and irrigation water in Iran, making it important to monitor toxic elements of pollutants in these resources in order to protect the inhabitants' health. The current study has been carried out to assess the health risks, caused by trivalent inorganic arsenic-polluted groundwater in Qaleeh Shahin Plain, an important agricultural regio...
