“…Several approaches have been developed to quantify groundwater recharge from precipitation, such as direct measurement, water-balance methods, and tracer techniques [2][3][4][5]. In order to improve recharge estimations, combining different techniques that are as independent as possible from each other is advisable [6][7][8][9]. The detailed application of many of these methods is costly and time consuming, and a long monitoring time is needed to obtain reliable results when direct methods are used [2].…”

Abstract:The chloride mass balance method was used to estimate the average diffuse groundwater recharge on northeastern Gran Canaria (Canary Islands), where the largest recharge to the volcanic island aquifer occurs. Rainwater was sampled monthly in ten rainwater collectors to determine the bulk deposition rate of chloride for the 2008-2014 period. Average chloride deposition decreases inwardly from more than 10 g·m . The application of the chloride mass balance method resulted in an estimated average recharge of about 28 hm 3 /year or 92 mm/year (24% of precipitation) in the study area after subtracting chloride loss with surface runoff. The average storm runoff was estimated to be 12 hm 3 /year (9% of precipitation) for the 1980-2014 period. Runoff was sampled during scarce rainy periods, which produce surface water flow. Average recharge varies from less than a few mm/year near the coast up to 270 mm/year in the highlands (about 33% of average rainfall), with a close-to-linear increase inwardly of about 18 mm·year. Recharge rate uncertainty corresponds to an estimated CV of 0.3-0.4 because of the short data series available.

“…Perhitungan imbuhan air tanah di area lain yang berbeda karakteristik lokasi, seperti telah dilakukan di wilayah Kabupaten Sleman oleh Indera Jati (2016) dengan metode Water Balance adalah 45 % dari rata-rata curah hujan. Contoh lainnya di wilayah Amerika Serikat, besaran imbuhan di wilayah irigasi sebesar 40% dari curah hujan (McMahon et al, 2011). Hal ini dapat dibandingkan bahwa area kota besar seperti Jakarta sudah menjadi area pemukiman, area padat atau area terbangun, sehingga dapat dikategorikan sebagai area kedap, sedangkan wilayah kabupaten Sleman masih mempunyai Ruang Terbuka Hijau (RTH) yang cukup luas.…”

“…Information is generally limited because of complex hydrogeology, difficulties in and costs of data collection, and the need for frequent monitoring. For example, recharge is considered to be one of the most difficult components of a water-balance to quantify accurately as it varies significantly in both temporal and spatial dimensions [12][13][14][15][16][17][18][19]. Effective management of groundwater aquifers is heavily influenced by the accurate estimation of recharge.…”

Abstract:Groundwater depletion in the face of growth is a well-known problem, particularly in those areas that have grown to become dependent on a declining resource. This research comprises a broad synthesis of existing water resources data, to understand the long-term implications of continued growth in water demand on groundwater dominant water resources, and to develop a tool for sustainable water management. The Palouse region of Washington and Idaho, USA. (approximately 60,000 people in a rural setting) is entirely dependent on groundwater from two basalt aquifers for potable water. Using the systems dynamics approach and a water balance that considered the entire hydrologic cycle, a hydrologic model of these aquifers was developed, tested and applied to simulate their behavior over a 150 year time period assuming the current infrastructure does not change. With 1% population growth and current water extraction rates, the results indicated the upper aquifer use may be sustainable, while the lower aquifer use is likely unsustainable in the long term. This study also shows that uncertainties in key aspects of the system create limitations to groundwater management.
