Basement Aquifers(地下含水层)研究综述
Basement Aquifers 地下含水层 - Thus, this study aims to estimate hydraulic properties of basement aquifers of the Idi-Ishin area of Ibadan, southwest Nigeria using an indirect electrical resistivity technique. [1] This study focused on the characterization of hydrodynamic properties of basement aquifers in six localities in the North of Cote d'Ivoire: Ganaoni, M'bengue, Tongon, Nielle, Ferke, and Tafire. [2] The generated groundwater recharge map was validated with available borehole records that established a relationship between the groundwater recharge mapped areas and basement aquifers. [3] ABSTRACT Hydrochemical, inverse geochemical modelling and isotopic approaches are used to assess the hydrogeochemical evolution of groundwater from the basement aquifers in the southeastern part of the Plateaux Region, Togo. [4] Although the socio-economic and hydrogeological conditions in SSA are diverse, they are sufficiently distinct (in general) from the conditions in North Africa to warrant being assessed separately— for example, high-yielding, high-storage, sedimentary aquifers are more common in North Africa than in SSA, while lowyielding, low-storage, basement aquifers are more widespread in SSA than in North Africa. [5]因此,本研究旨在使用间接电阻率技术估计尼日利亚西南部伊巴丹 Idi-Ishin 地区地下含水层的水力特性。 [1] 本研究的重点是描述科特迪瓦北部六个地区地下含水层的水动力特性:Ganaoni、M'bengue、Tongon、Nielle、Ferke 和 Tafire。 [2] 生成的地下水补给图通过可用的钻孔记录进行验证,该钻孔记录建立了地下水补给映射区域和地下含水层之间的关系。 [3] 摘要 水化学、逆地球化学建模和同位素方法用于评估多哥高原地区东南部基底含水层地下水的水文地球化学演化。 [4] 尽管 SSA 的社会经济和水文地质条件多种多样,但它们(总体上)与北非的条件有很大不同,值得单独评估——例如,高产、高储量的沉积含水层在北非更为常见。与 SSA 相比,北非,而 SSA 中低产、低储量的地下含水层比北非更广泛。 [5]
Crystalline Basement Aquifers 结晶地下含水层
Delineating crystalline basement aquifers with adequate capacity to store and transmit sufficient groundwater is quite challenging as substantial spatial variability predominantly marked the basement aquifers. [1] Knowledge on hydraulic characteristics of fractured crystalline basement aquifers is limited resulting to lack of reliable information for effective groundwater management. [2] Nevertheless, assessment of the sustainable reservoirs in crystalline basement aquifers is challenging. [3] Assessment of the groundwater potential of crystalline basement aquifers is challenging. [4] As a result, groundwater acquisition in this terrain is challenging compared to crystalline basement aquifers. [5] However, any significant increase in population growth may result in water scarcity in these areas, as the Crystalline Basement aquifers generally have low yielding capacity. [6]划定具有足够储存和输送足够地下水的能力的结晶基底含水层是相当具有挑战性的,因为大量的空间变异性主要标志着基底含水层。 [1] 由于缺乏有效地下水管理的可靠信息,对裂缝性结晶基底含水层水力特性的了解有限。 [2] 然而,对结晶基底含水层中可持续储层的评估具有挑战性。 [3] 结晶基底含水层地下水潜力的评估具有挑战性。 [4] 因此,与结晶地下含水层相比,该地形的地下水采集具有挑战性。 [5] 然而,人口增长的任何显着增加都可能导致这些地区的水资源短缺,因为结晶地下含水层通常具有低产量能力。 [6]
Fractured Basement Aquifers
The integrated approach provides a reliable study to better understand the groundwater occurrence in fractured basement aquifers. [1] As the contribution from the Nubian water component increase (becomes 50% or more), the simulation of mixing accompanied with evaporation of 90% gives a similar composition to both of the Alluvium and fractured basement aquifers which contain more mineralized water. [2] Chlorine-36 abundances and stable chlorine isotope ratios ( 37 Cl/ 35 Cl) were analyzed to decipher sources of chloride and to estimate subsurface residence times of groundwaters from the Nubian Sandstone Aquifer System (NSAS), alluvial aquifers, and fractured basement aquifers in the Eastern Desert of Egypt. [3]综合方法提供了一项可靠的研究,以更好地了解裂缝性地下含水层中的地下水存在情况。 [1] 随着努比亚水成分的贡献增加(变为 50% 或更多),伴随 90% 蒸发的混合模拟给出了与含有更多矿化水的冲积层和裂缝性基底含水层相似的成分。 [2] 分析了 Chlorine-36 丰度和稳定氯同位素比 ( 37 Cl/ 35 Cl) 以破译氯化物的来源,并估计努比亚砂岩含水层系统 (NSAS)、冲积含水层和断裂基底含水层中地下水的地下停留时间埃及东部沙漠。 [3]
