“…These include water harvesting and use of qanats. Rainwater harvesting can be used to recharge groundwater via recharge ponds (Sukhija et al 1997). Qanats are drainage tunnels commonly found in the arid and semi-arid areas of Europe, North Africa and Asia (Castellani & Dragoni 1997;Issar & Zohar 2007).…”

There is a general consensus that climate change is an ongoing phenomenon. This will inevitably bring about numerous environmental problems, including alterations to the hydrological cycle, which is already heavily influenced by anthropogenic activity. The available climate scenarios indicate areas where rainfall may increase or diminish, but the final outcome with respect to man and environment will, generally, be detrimental. Groundwater will be vital to alleviate some of the worst drought situations. The paper analyses the main methods for studying the relationships between climate change and groundwater, and presents the main areas in which hydrogeological research should focus in order to mitigate the likely impacts.

“…Other simple soil models can also be used to estimate water recharge, by calculating how much water is potentially available for groundwater recharge from the differences among the measured rainfall, the estimated actual evapotranspiration and the soil moisture (Ragab et al 1997;Chapman and Malone 2002). As well as the aforementioned physical models, the measured distribution of environmental tracers, 3 H, 36 Cl and chloride, in a soil water profile, have also been used to estimate the rate of movement of water in soil, to locate a groundwater aquifer (Eriksson and Khunakasem 1969;Sukhija et al 1997;Cook and Robinson 2002).…”

Artificial recharge is a practical tool available for increasing the groundwater storage capacity. The efficiency of artificial recharge is related to various hydrogeological factors of the target area. In this study, a variable saturated groundwater flow model, FEM-WATER, was used to evaluate the arrival times of recharged water that infiltrates from an artificial recharge pond to the groundwater table under various hydrogeological conditions. Forty-five arrival times were generated by FEMWATER. The relationships between the arrival times and hydrogeological factors used in the simulation of FEMWATER were analyzed by the grey correlation method. The results show the order of importance of the factors as they influence the arrival time. In order from high to low importance, they are a, D g , h e , D p , K S and b. D g and D p are interpreted as the potential for movement of the recharge water; h e is the water storage capacity of soil, and K S represents the ability of soil to transport water. a and b describe the characteristic curve of the unsaturated soil. The method was applied to evaluate a suitable site for artificial recharge in the Yun-Lin area. Grey correlation analysis was performed to obtain the grey correlation grade using the minimum arrival time as a reference sequence. An index is proposed herein to determine the recharge efficiency of 20 sampling sites. A contour mapping of index values at the 20 sampling sites identified three areas for artificial aquifer recharge in Yun-Lin. Area A in the upper plain is considered more appropriate for groundwater recharge than areas B and C in the coast.

“…The evaluation of an artificial recharge structure in hard-rock terrain attempted by Muralidharan and Venugopalan Nair (1998) using tracer studies indicated that only 30-35% is contributed by deep percolation (recharge to groundwater); the rest is accounted for by evaporation loss from storage and soil moisture evaporation loss during recession of storage, as quantified in their investigations. The work carried out by Sukhija et al (1997) using tank-water chloride balance indicated that the percolation efficiency is about 60%. Sukhija et al (1997) also reported that the efficiency reduces in consecutive years due to silt accumulation in the tank bed area.…”

Under a sustainable groundwater development and quality management project over a semi-arid granite terrain, several rainwater harvesting structures were proposed based on geophysical investigations in the study area. In order to validate the site suitability and check the efficacy of the recommended recharge structures in terms of source sustainability, certain hydrological tests, such as infiltration studies, were conducted within the recharge area of these structures. Infiltration rate estimation using a double-ring infiltrometer normally results in an exponential decay relationship with high initial infiltration rate followed by gradual reduction until, ultimately, a stabilized rate is attained. In this paper, we present the results of infiltration tests conducted using a doublering infiltrometer (under constant head condition) within the tank bed area of a proposed percolation tank site. The results showed unique features in the infiltration rate at different time intervals within the total experimental period: a staircase-like evolution with intermittent stabilization for a short duration. Based on the integrated approach of geophysical investigations, hydrological tests, and supported by physical evidence, the infiltration behaviour observed over the study area was considered to be due to the lithological stratification with different permeability and textural conditions.

Afin de valider la pertinence des sites et d'évaluer l'efficacité des structures de recharge préconisées en termes de durabilité, certains tests hydrologiques, comme des études d'infiltration, ont été menés au sein de la zone de recharge de ces structures. L'estimation du taux d'infiltration à l'aide d'un infiltrométre à double anneau aboutit normalement à une relation décroissante exponentielle avec un fort taux d'infiltration initial suivi par une diminution graduelle jusqu'à ce qu'un taux stabilisé soit atteint à terme. Dans cet article, nous présentons les résultats de tests d'infiltration menés avec un infiltrométre à double anneau (sous conditions de charge constante) dans la zone du fond du réservoir d'un site proposé pour accueillir un réservoir d'infiltration. Les résultats montrent des valeurs uniques de taux d'infiltration au fil du temps pendant la période expérimentale totale: une évolution en escalier avec des stabilisations intermittentes pendant de courtes durées. Sur la base de l'approche intégrée des études géophysiques, des tests hydrologiques, et d'éléments physiques, le comportement de l'infiltration observé dans la zone d'étude apparaît être dû à la strat...
