“…On the other hand, managed aquifer recharge can be utilized to increase water resources [4], to alleviate seawater intrusion and land subsidence, both derived from groundwater overexploitation [5][6][7]. This technology also can be used to improve the quality of reclaimed water and desalinated water [8][9][10][11][12][13][14] and could even serve as a water conveyance system [15]. Consequently, it has been a robust water resources management technology in addressing existing challenges nowadays and can furthermore meet larger water demand under more severe drought conditions in the future [3].…”

The vadose zone plays a significant role during artificial recharge via the infiltration basin. Its thickness, lithology, heterogeneity, among others greatly affect the recharge efficiency. The main objective of this research is to establish the role of the vadose zone and the impacts of infiltration basin features and vadose zone factors on water distributions. In this work, an ideal conceptual model was considered, and mathematical models were built using HYDRUS (2D/3D) software package version 2.05. A total of 138 numerical experiments were implemented under seven types of experimental conditions. The experimental data were analyzed with the aid of correlation and regression analysis. The results showed that infiltration basin features and vadose zone factors had various impacts on water distribution, low permeability formation had various effects on evaporation depending on its depth, and there were consistent, similar, or different variation trends between infiltration and recharge. In conclusion, it is recommended that when the vadose zones are to be chosen as an infiltration basin site, the trade-off among the infiltration, recharge, storage, and evaporation should be seriously considered. This paper may contribute to a better understanding of the vadose zone as a buffer zone for artificial recharge.

“…In many countries, especially those located in arid to semi-arid regions, precautions are taken against water scarcity [1,2]. Optimization of well field management practices and water quality protection received much attention in different regions in the world [3][4][5][6][7][8][9][10][11]. One of the effects of water scarcity is the lack of enough drinking water supply to the population and this issue can be worsened by improper wellfield management.…”

Implementation of Simple Strategies to Improve Wellfield Management in Arid Regions: The Case Study of Wadi Al Arab Wellfield, Jordan

et al. 2019

Groundwater is the main source of drinking water supply in Jordan. Over the past 30 years, many wellfields have been drilled and expanded to cover increasing drinking water demand caused by natural population growth, development of life standards and as a result of the influx of refugees to Jordan. In particular, northern Jordan groundwater resources have been severely depleted. Therefore, water suppliers and utilities have been increasingly challenged to meet water demand and deliver water of adequate quality and quantity to households in a timely manner. Meeting these objectives requires good data management, proper maintenance of groundwater wells, and effective wellfield management plans. We developed a novel monitoring strategy that allows the collection of relevant data for wellfield managers (e.g., yield, static and dynamic water level, as well as energy consumption). The new monitoring system, implemented in 2017, has greatly enhanced data availability in comparison to the situation between 2012 and 2016. The data are used in an operational decision support tool based on simple interpretation of the field observations. The implementation of the project was done using both bottom-up and top-down approaches for the Wadi Al Arab wellfield. Our results evidence that (i) simple strategies can lead to a significant improvement of wellfield management, reducing the maintenance time of the wells though appropriate monitoring (from an average of four days/maintenance/well in 2012 to less than one day/maintenance/well in 2017); (ii) the joint combination of bottom-up and top-down approaches leads to an effective implementation of the monitoring system; (iii) the simplicity of the proposed monitoring strategy makes it suitable for further implementation in other wellfields in Jordan and countries in a similar situation of both data and water scarcity.

An Assessment of Water Resources in the Taiwan Strait Island Using the Water Poverty Index

2020

Water resources are a very important issue in the Global Risk 2015 published by the World Economic Forum. The research objective of this study was to construct a Water Poverty Index (WPI) for islands. The empirical scope of this study was based on Kinmen Island in the Taiwan Strait, which has very scarce water resources. Kinmen has a dry climate with low rainfall and high evaporation. Therefore, the Kinmen area is long-term dependent on groundwater resources and faces serious water resource problems. This study used the WPI to examine various issues related to water resources. In addition, this study selected several main indicators and performed time series calculations to examine the future trends of water resources in Kinmen. The results show that the overall water resources of Kinmen are scarce. To ensure sustainable development of water resources in Kinmen, policies to improve water scarcity, such as water resource development, water storage improvement, and groundwater control, should be researched. The research results of this study can be used as a reference for government agencies in formulating and revising water resources to achieve the sustainable development of island-type water resources.In the past decade, especially within environmental politics, there has been a growing interest in, and concern for, the ways in which discourses are constructed, used, and misinterpreted in public political debates about shared water resources [17][18][19]. Because of the aforementioned issues, the Centre for Ecology and Hydrology (CEH) in the UK began to develop the Water Poverty Index (WPI) in 2002 [20]. The main purpose of the WPI is to provide a numerical value that can be used to calculate how much national welfare is represented by water and to denote the extent of water poverty's effects on humans. The main considerations in this index system are water availability, water accessibility, the ability for people to acquire water, and the background environmental quality of water conservation for a country or a region. The development of this index makes the ranking and comparison of countries or communities possible and can consider various physical and socioeconomic factors of water scarcity [20].The WPI uses the local scale as its starting point for development. A WPI has been developed and applied to various countries, such as South Africa, Sri Lanka, and Tanzania. In 2002, the WPI team considered the commonality and accessibility of national data in the WPI architecture for the three aforementioned countries to develop a WPI suitable for the nation, based on the use in [21]. Water is a vital resource for natural ecosystems and for sustainable human life [22], especially in arid and semiarid regions [23]. Water bodies are the focus of the interactions among various components of the terrestrial system, and, in many areas, they are the most important freshwater resources [24]. This comprehensive indicator will guide the improvement of various issues related to water resources and enable policy makers to imple...
