Abstract Knowledge of the hydraulic and geological properties karst systems is particularly valuable to hydrogeologists because these represent an important source potable water in many countries. However, high heterogeneity that characterizes complicates definition hydrogeological properties, their estimation involves complex expensive techniques. In this study, a workflow for spring characterization was used analyze two springs, Nanto Mossano spring, located Berici Mountains (NE Italy)....

Abstract. The hydrogeological characteristics of roto-translational slides in flysch are complex, due to the inherent anisotropy and heterogeneity rock masses related deposits. paper deals with characterization a reactivated slide affecting Cretaceous rocks, located northern Apennines Italy. Continuous monitoring groundwater levels, in-situ permeability pumping tests, hydrochemical physical analyses Uranine tracers were adopted prospecting methods. In this research hydrological investigation...

The Euganean Geothermal Field (EGF) is the most important thermal field in northern Italy. It located alluvial plain of Veneto Region where approximately 17*106 m3 water with temperatures 60–86 °C are exploited annually. A regional-scale conceptual model System proposed this paper using available hydrogeologic, geochemical and structural data for both EGF central Veneto. meteoric origin infiltrates 80 km to north Prealps. flows south a Mesozoic limestone dolomite reservoir reaching depth...

Abstract The interest on low‐temperature geothermal resources is progressively increasing since their renewability and widespread availability. Despite frequency, these development have been only partially investigated. This paper unravels the major physical processes driving a resource in NE Italy (Euganean Geothermal System) through conceptual numerical modeling. Dense fracturing associated to regional fault zones relay ramp enhances local flow of thermal waters. Their rapid upwelling...

The point dilution test is a single-well technique for estimating horizontal flow velocity in the aquifer surrounding well. conducted by introducing tracer into well section and monitoring its decreasing concentration over time. When using salt tracer, method easy inexpensive. Traditionally, Darcy calculated as function of rate based on simple assumption that proportional both to apparent aquifer. In this article, an alternative approach analyse results tests proposed verified data acquired...

Abstract This work proposed a novel method to elucidate the controls of As mobility in complex aquifers based on an unsupervised machine learning algorithm, Self‐Organizing Map (SOM), and process‐based geochemical modeling. The approach is tested shallow Venetian Alluvial Plain (VAP) near Venice, Italy, where concentrations seasonally locally exceed recommended drinking water limits. SOM was fed using information from two surveys eight VAP boreholes, continuous reading hourly groundwater...

Defining aquifer permeability distribution accurately over large areas is often debated in hydrogeology. The operational efforts to calculate hydraulic conductivity with classical tests are significant; however, accurate knowledge of areal fundamental both from a hydrogeological and modeling standpoint. This paper presents an empirical relationship between the transmissivity (T) specific capacity (SC) values obtained experimental well tests. All were 50 mm wells middle Venetian plain...

Abstract Renewable natural resources are strategic for reducing greenhouse gas emissions and the human footprint. The renewability of these is a crucial aspect that should be evaluated in utilization scenario planning. geothermal strictly related to physical geological processes favor water circulation heating. In Veneto region (NE Italy), thermal waters Euganean Geothermal System most profitable regional resource, its assessment entails evaluation fluid heat recharge, local settings,...

Nowadays, several methodologies, implemented for satellite or terrestrial surveys, reveal that daily and weekly site-positioning time series can exhibit linear trends plus seasonal oscillations. Such periodic components affect the evaluation of subsidence rates and, thus, they must be recognized properly modelled. In this work, component vertical land motion in Po Delta (Northern Italy) is estimated by a multi-component multi-source procedure recently proposed some authors studying delta...

The project of interest involving a hydroelectrical diversion tunnel through crystalline rock massif in the Alps required detailed hydrogeological study to forecast magnitude water inflows within and possible effects on groundwater flow. exhibits length 9.5 km is located right side Toce River Crevoladossola (Verbania Province, Piedmont region, northern Italy). Under geological framework Alps, Lower Penninic Nappes footwall Simplon Normal Fault, succession mostly represented by Antigorio...

The aim of the article is to show role redox potential and ammonium ion concerning release arsenic into groundwater from naturally occurring sources. study carried out on both regional local scale. former performed area drainage basin Venice lagoon (DBVL), while latter interests a sub-area near Porto Marghera contaminated sites national interest, named Agricultural west areas (AWA). results work will elucidate processes continuity at different scales.

Stochastic multicomponent reactive transport modeling is a powerful approach to quantify the probability of non-exceedance (PNE) arsenic (As) critical concentration thresholds in groundwater. The applied well-characterized shallow alluvial aquifer near Venice, Italy. Here, As mobility depends primarily on rainfall-controlled redox-dependent precipitation-dissolution iron hydroxides. A Monte-Carlo analysis based calibrated three-dimensional flow and model targeted geochemical initial...

The article presents an example of well-head protection area (WHPA) delineation in middle Venetian plain, using geostatistical simulation for the subsoil reconstruction, groundwater flow modeling and automatic calibration.
