Special Issue Information

Dear Colleagues,

Groundwater is the world's largest freshwater resource. However, in light of the increasing population, an ecology-based but economic management is required for its sustainability. Besides the basic questions of groundwater recharge and tolerable abstraction volumes, particular attention should be paid to the diverse interactions between aquifers and surface waters decisive for the movement of water and the substances transported in catchments and landscapes or over regions. Most of the world's rivers are mainly fed by groundwater outflow from adjacent aquifers. The abstraction of groundwater will decrease their flows, with a particular impact on low flows. With lowering groundwater levels, perennial rivers recharged by continuous groundwater flow turn into intermittent rivers. Additionally, vegetation and soil use, forests, agriculture, irrigation, urbanization, etc., have impacts, sometimes temporarily, often seasonal, bringing up questions about groundwater storage recuperation and water balances. Subsurface, thus groundwater, catchments of rivers often significantly differ in their areas from topographic surface catchments. However, hydrologic models are still mostly based on surface size, topography, and morphology, which can lead to gross misjudgments.

This Special Issue is dedicated to studies on groundwater use and management; the quantification of hydrological, hydraulic, geochemical, biological, and anthropogenic impacts; and the interaction with surface waters. It will be a collection of research studies conducted by the interdisciplinary groundwater community, which deals with groundwater by treating it as not only an engineering problem but also an economical, ecological, and social issue.

Groundwater is a strategic resource in all climatic regions of Ethiopia, contributing about 80% of the domestic supply of urban and rural populations. However, little research has been available compared with extensive geographical coverage and increasing population growth rates. Hence, the present study aimed to review published groundwater research of Ethiopian aquifers to realize potential research challenges and suggest future research directions. We focused on groundwater potential, recharge process, and qualities. The total potential groundwater of the country ranges from 2.5 to 47 billion cubic meters. The study depicted that the mean annual recharge estimate varies from 24.9 mm to 457 mm at catchments scales. However, the overall country was about 39.1 mm. The study found a need for a detailed investigation of different factors susceptible to groundwater pollution, as some of the evaluations indicated exceeding acceptable standards. This study observed that the main challenge was the lack of data and convergence research trends. Henceforth, future research in different climate regions should focus on multifaceted technical and stakeholder settings. This study gives the insight to integrate palatable research findings with the national policy and decision-making process to enhance the sustainability of groundwater resources significantly.

Abstract: Karst aquifers are important water reservoirs. Due to their freshwater storage capacity, they have a significant role in the water cycle. This study aims to determine sea-water intrusion dynamics of Gökova Basin and several springs (more than 40 springs side by side) of Azmak Stream in Muğla, Ula, Turkey. In this study, water samples from the Azmak springs were analysed. In-situ physi-co-chemical measurements, major ion, stable and unstable isotope analyses were carried out on wells, surface waters and selected springs in the recharge basin. In addition, geological field studies were conducted, some sections started from recharge basins to discharge point were obtained. The hydrogeology of the area was interpreted based on the geological sections and perviousness map. The sampling procedure was continued monthly for 13 selected spring locations. The results of each spring location were explained in the scale of seasons. The preliminary results show that δ18O values is between ‰ -6.67 and ‰ -7.34. δD values vary between ‰ -29.29 and ‰ -38.67. D-excess values show variance between ‰ 7.34 to ‰ 21.47 for each spring location at seasonal scale. The collected data were also evaluated by various statistical analyses. It has been found that the Azmak springs comprise 3 groups in terms of different recharge conditions. It has also been determined that the group showing more freshwater characteristics is recharged from the Muğla-Yerkesik sub-basins, the group showing moderate salinity is recharged from the Ula and Gökova sub-basins and the most saline group is predominantly controlled by the seawater intrusion. In light of the results obtained in this study, new findings regarding the relationship between the Muğla basin and the springs, which is ambiguous in the literature, have been put forward and it has also been de-termined that the springs have different recharge basins. These findings are predicted to be bene-ficial for the sustainable management of groundwater in the region.
