“…Uses. The groundwater quality is of fundamental relevance for irrigation and drinking purposes [3], also in the northern bank of the Mediterranean, affected by climate change evolving toward semiarid to arid conditions, e.g., [49] and references therein. The amount of dissolved ions affects the agricultural productivity influencing both the growth of plants and soil structure [50].…”

The High Agri Valley (southern Italy) is one of the largest intermontane basin of the southern Apennines affected by intensive agricultural and industrial activities. The study of groundwater chemical features provides much important information useful in water resource management. In this study, hydrogeochemical investigations coupled with multivariate statistics, saturation indices, and stable isotope composition (δD and δ18O) were conducted in the High Agri Valley to determine the chemical composition of groundwater and to define the geogenic and anthropogenic influences on groundwater quality. Twenty-four sampling point ( including well and spring waters) have been examined. The isotopic data revealed that groundwater has a meteoric origin. Well waters, located on recent alluvial-lacustrine deposits in shallow porous aquifers at the valley floor, are influenced by seasonal rainfall events and show shallow circuits; conversely, spring waters from fissured and/or karstified aquifers are probably associated to deeper and longer hydrogeological circuits. The R -mode factor analysis shows that three factors explain 94% of the total variance, and F1 represents the combined effect of dolomite and silicate dissolution to explain most water chemistry. In addition, very low contents of trace elements were detected, and their distribution was principally related to natural input. Only two well waters, used for irrigation use, show critical issue for NO3- concentrations, whose values are linked to agricultural activities. Groundwater quality strongly affects the management of water resources, as well as their suitability for domestic, agricultural, and industrial uses. Overall, our results were considered fulfilling the requirements for the inorganic component of the Water Framework Directive and Italian legislation for drinking purposes. The water quality for irrigation is from “good to permissible” to “excellent to good” although salinity and relatively high content of Mg2+ can occasionally be critical.

“…The relationship between water resources management and land use/cover is highly relevant, inextricably entwined, and the need to protect the quantity and quality of water resources can influence potential land uses and land management practices [7,8]. Although this relationship is complex with respect to surface basins and groundwater recharge due to diversity with topography, as well as hydrogeological characteristics [9], water-makers, from governments to nonprofits to corporations, often manage water resources and land use for multiple uses [10,11].…”

This paper presents the calculation and management of water supply and demand under land use/cover changes in the Yarmouk River Basin in Jordan for the years 1997, 2007 and 2017. It aims to analyze and link the changes in the land classes with the water resources supply demand as the groundwater is unable to meet the inhabitants demand, necessitating land management practices. The method includes deriving land use/cover maps using the supervised classification, identifying basin governorates, cities and villages, calculating the basin governorates’ inhabitants, water demand, supply of internal wells, water loss, and actual water consumption. The results showed an increase in the urban area by 3.01%, while forests, rain-fed vegetables and crops declined by 1.57% and 1.09%, respectively. Urbanization appears mainly at the expense of rangelands, an important change affecting water supply from internal wells due to increased pumping to balance population demand. Although it is decreasing per capita, the water demand is high. Changing land use practices, securing inter-basin water resources, and calculating water losses is a challenge of great importance that can manage water shortages and increase actual consumption. This research is important in order to understand the supply demand situation and to aid a wide range of users, water-managers, land-planners and decision-makers.

“…In particular, the Mediterranean region is often regarded as a hot spot of climate change with a predicted temperature increase of 3.5-5.5 °C until 2100 (Bonacci et al 2020;Branković et al 2013) and an increase in precipitation variability with a negative influence on water balance (Aguilera and Murillo 2008;Touhami et al 2015). The environmental challenges in the Mediterranean region are fostered by the rising anthropic pressure and the high population density with the local population (approximately 160 million people with approximately 10 million inhabitants in the islands; European Environment Agency 2015) drastically increasing during the tourist season (e.g., Leduc et al 2017;Mongelli et al 2019).…”

Multidisciplinary investigations of a karst reservoir for managed aquifer recharge applications on the island of Vis (Croatia)

Managed aquifer recharge (MAR) refers to a suite of methods by which excess surface water or non-conventional water is stored underground for subsequent recovery or environmental purposes. MAR solutions have been largely used in unconsolidated aquifers, while their application in karst aquifers is rare. This research presents the first results of a MAR viability study on the island of Vis, a small karstic island in the Adriatic Sea. Favorable geological and hydrogeological conditions enable the formation of karst aquifers, making the island autonomous in terms of water supply. The island’s main aquifer, exploited in the Korita well field, is protected from seawater intrusion by several hydrogeological barriers. However, climate change and high seasonal pressures related to tourism pose a threat to the future availability of freshwater. Multidisciplinary field and laboratory investigations were carried out to detail the geological and hydrogeological setting of the island and its groundwater resource. Field analyses consisted of groundwater monitoring and sampling, geophysical investigations (i.e., electrical resistivity tomography), and structural measurements. Laboratory analyses included measurements of principal cations and anions and tritium activity. Despite low precipitation during the observation period (September 2019 - December 2020), the groundwater resource at the Korita site showed stable trends of physico-chemical parameters with a good storage potential and a long-term reserve. Geophysical investigations evidenced a relatively homogeneous sequence of the rock mass at a larger scale, while structural analyses indicated the occurrence of E-W karstified and open fractures that could represent a preferential flow path in the carbonate aquifer. A MAR solution for the Vis island was proposed combining an infiltration pond scheme with the direct injection of the accumulated waters into the aquifer using available wells. The potential water source could be represented by the runoff collected in an old artificial channel and the associated pond system in Korita.
