The mixing of different sources and biogeochemical processes regulates nitrate concentrations and its isotopic composition72. The variation pattern of nitrate concentrations and their isotopes with aquifer depth further highlights the crucial role of biological activity in nitrogen dynamics (Fig. 3). Specifi...
Its freshwater supply depends mainly on groundwater, with over 300,000 wells throughout the country (Daskalaki & Voudouris, 2008). Intense urbanization, the development of tourism, and the expansion of agricultural land attend to intensive exploitation of water resources, especially from April to ...
Aquifer Definition, Types & Examples from Chapter 8 / Lesson 11 42K Explore aquifers. Learn the definition of an aquifer and understand its importance. Discover confined aquifers and unconfined aquifers and find how they work. Related to this QuestionHow...
Yet the abundance of the putatively obligate aerobe, Meiothermus, increased with depth, providing an opportunity to evaluate the influence of chemical and spatial variation on its distribution and speciation. Two clades of Meiothermus metagenome assembled genomes (MAGs) were identi...
Distribution of karst aquifers within the United States and its territories based on USGS data is presented herein (Fig. 2). Detailed geological investigations in Puerto Rico show that limestone, dolomite, gypsum and anhydrite are the most common materials forming Puerto Rican karst aquifers (Fig. ...
its characteristic hydrogeological setting. The alluvial aquifer is strongly conditioned by the presence of a buried tectonic discontinuity along which the saline waters are mainly distributed. These waters rise along the discontinuities in the bedrock and flow into the overlying alluvial aquifer. ...
The system must then be registered, so the sensor is roughly in the middle of its measurement scale prior to testing. To avoid the sensor going off scale and becoming nonfunctional, the Tilt-X design included a registration system. [30] The registration system on the Tilt-X (Figure 1) ...
(2008) between the average annual discharge of a spring from field monitoring (QA) and its average discharge during hydrological recession in the low flow season, i.e. summer in the investigated climate (QS). Such correlation was derived experimentally starting from a large dataset of 11 ...
38. The ability of ML models to model groundwater salinity has been demonstrated via the establishment of a linear or non-linear relationship between water salinity and its control parameters (such as water table, evaporation, and distance to saltwater bodies) and using those relationships for the...
Pantosti and Valensise1990; Boncio and Lavecchia2000; Deschamps et al.2000; Chiarabba et al.2009). The 2016–2017 sequence and its main shocks (Table1) were generated by the Gorzano Mt.-Vettore Mt.-Bove Mt. faults (Galadini and Galli2003, LMF and MVF in Fig.2). The seismic crisis...
