“…Groundwater depletion (see Chap. 3) occurs when rates of groundwater recharge are less than rates of discharge. Over the last 50 years, groundwater depletion from direct or indirect effects of climate change and human activities, such as groundwater pumping for irrigated agriculture or urban centers (Bouraoui et al 1999;Dams et al 2007), has expanded from a local issue to one that affects large regions in many countries throughout the world (Alley et al 2002;Brouyere et al 2004;Hsu et al 2007;Martin-Rosales et al 2007;Moustadraf et al 2008). Changing global groundwater discharge has even contributed to sea-level rise during the past century (Taylor et al 2013).…”

“…Sea-level rise, spatiotemporal changes in precipitation and evapotranspiration, which affect recharge, and increased groundwater pumping will likely result in more groundwater salinisation in many coastal regions (Barrocu and Dahab 2010;Beuhler 2003;IPCC 2007a;Klein and Nicholls 1999;Kundzewicz et al 2007;Moustadraf et al 2008;Oude Essink 1996;Oude Essink 2001, 2004Oude Essink et al 2010;Pierson et al 2001;Ranjan et al 2006a, b;Sharif and Singh 1999;Yechieli et al 2010). Vandenbohede et al (2008) simulated a likely 15 % increase in recharge across a Belgian coastal aquifer over the next 100 years.…”

Projected global change includes groundwater systems, which are linked with changes in climate over space and time. Consequently, global change affects key aspects of subsurface hydrology (including soil water, deeper vadose zone water, and unconfined and confined aquifer waters), surface-groundwater interactions, and water quality. Research and publications addressing projected climate effects on subsurface water are catching up with surface water studies. Even so, technological advances, new insights and understanding are needed regarding terrestrial-subsurface systems, biophysical process interactions, and feedbacks to atmospheric processes. Importantly, groundwater resources need to be assessed in the context of atmospheric CO 2 enrichment, warming trends and associated changes in intensities and frequencies of wet and dry periods, even though projections in space and time are uncertain. Potential feedbacks of groundwater on the global climate system are largely unknown, but may be stronger than previously assumed. Groundwater has been depleted in many regions, but management of subsurface storage remains an important option to meet the combined demands of agriculture, industry (particularly the energy sector), municipal and domestic water supply, and ecosystems. In many regions, groundwater is central to the water-food-energy-climate nexus. Strategic adaptation to global change must include flexible, integrated groundwater management over many decades. Adaptation itself must be adaptive over time. Further research is needed to improve our understanding of climate and groundwater interactions and to guide integrated groundwater management.

“…The quality of groundwater, particularly in the coastal areas of Kuala Linggi, is diminished by salt water due to intrusion of seawater. Excessive pumping and decreasing recharge rate caused aquifer depletion and led to the intrusion of seawater [MOUSTADRAF et al 2008;PUJARI, SONI 2008;RANGZAN et al 2008;ZHOU 2009]. Coastal areas of this region are often subjected to the brackish and salty inflows both on alluvium stone and hard rock stone.…”

Groundwater quality and aquifer productivity of Malacca catchment in Peninsular Malaysia are presented in this article. Pumping test data were collected from 210 shallow and 17 deep boreholes to get well inventory information. Data analysis confirmed that the aquifers consisting of schist, sand, limestone and volcanic rocks were the most productive aquifers for groundwater in Malacca state. GIS-based aquifer productivity map was generated based on bedrock and discharge capacity of the aquifers. Aquifer productivity map is classified into three classes, namely high, moderate and low based on discharge capacity. Groundwater potential of the study area is 35, 57 and 8% of low, moderate and high class respectively. Fifty two shallow and 14 deep aquifer groundwater samples were analyzed for water quality. In some cases, groundwater quality analysis indicated that the turbidity, total dissolved solids, iron, chloride and cadmium concentrations exceeded the limit of drinking water quality standards.

“…Proposed models include Man-Kendal method, t test and Cradock tests , artificial neural network approach (Polemio and Casarano 2008;Salami and Ehteshami 2016), and time series analysis methods like spectral and correlation analysis (Aflatooni and Mardaneh 2011; Nayak et al 2006;Chen et al 2004; Lee et al 2005), and moving average (Rajmohan et al 2007;Reghunath et al 2005). In regions where accurate hydrologic data are inaccessible the groundwater level fluctuations can be predicted using stochastic methods like principle component analysis (PCA) and cross correlation analysis methods (Moustadraf et al 2008).…”

In the world's water scarce regions, groundwater as an important and strategic resource needs proper assessment. An accurate forecasting needs to be performed in order to make a better identification of fluctuating nature of groundwater levels. In this study, groundwater level fluctuations of Kabudarahang aquifer was synchronized and verified. Investigation was conducted with usage and application of time series models. Groundwater level data during 2003-2014 are used for calibration and analyses were performed using Box-Jenkins models. Residual error analysis and comparison of observed and calculated groundwater levels were performed. Then a prediction model for groundwater level in Kabudarahang aquifer developed. The model was used for predicting the groundwater level during 2014-2017. Model results showed that the groundwater level in this aquifer will endure a 5 m decline for the next three upcoming years.
