In arid and semi-arid ecosystems shortage of surface water has led to a greater use of groundwater resources. Water table in groundwater due to climate and human intervention is always fluctuating. Assessing change groundwater resource in planning and sustainable management of water resources in each region has of great importance. In this study were investigated changes of water table in the p...
Water plays a vital role in the development of activities in an area. The surface water resources are inadequate to fulfill the water demand. Productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. Keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...
Introduction: Drought is a natural hazardous phenomenon occurring in all climate types. However, it affects arid and semiarid regions more intensely than other areas. It also severely affects both the quantity and quality of water resources in arid zones. Moreover, land-use changes and urban and agricultural development also adversely influence water resources in these regions, especially groun...
Groundwater is an important, but undervalued, national resource in Scotland. Groundwater is present both in the bedrock, where much of the flow is through fractures, and in the superficial deposits, where intergranular flow dominates. The most productive bedrock aquifers are the Permian sandstones and breccia in SW Scotland and the Devonian sandstones in Fife, Strathmore and Morayshire. Alluviu...
Nowadays, the increase in population growth rate and followed by anthropogenic activities such as urbanization, industrialization, mining and agriculture practices continuously increase the amount of heavy metals in the environment especially groundwater resources. Therefore, qualitative assessment of groundwater resources is of great importance for maintaining public health and for this reason...
Groundwater Level Changes Due to Extreme Weather—An Evaluation Tool for Sustainable Water Management
In the past decade, extreme and exceptional droughts have significantly impacted many economic sectors in the US, especially in California, Oklahoma, and Texas. The record drought of 2011–2014 affected almost 90% of Texas areas and 95% of Oklahoma state areas. In 2011 alone, around $1.6 billion in agricultural production were lost as a result of drought in Oklahoma, and $7.6 billion in Texas. T...
Background & Aims of the Study: Due to the increasing pollution of water resources, tow documented methods: the Heavy metal potential index (HPI) and the Heavy metal evaluation index (HEI) were evaluated for their suitability for contamination monitoring of heavy metals (As, Zn, Pb, Cd and Cu) contamination in groundwater resources of Asadabad Plain during spring and summer in 2012. Material...
in recent decades, using water resources is increased for the sake of industrial, domestic and agricultural water consumptions by increase in urbanization and industrial development in karaj region that fraction of groundwater resources is too much according to the recent drought years and reduced precipitation in middle-east. these outcomes has caused groundwater level drop, reduced in aquifer...
Groundwater recharge is essential to groundwater resources availability to economy and society development in semiarid areas. Chloride mass balance method to assess groundwater recharge have been review and was employed to quantify groundwater recharge in North Okanagan which is a semiarid mountainous terrain, southern interior British Columbian, Canada. Chloride concentration in precipitation ...
