Journal of Maps, 2016 This paper describes the contents of the new Hydrogeological Map of the City of Rome (1:50,000 scale). The map extends to the entire municipality (1285 km2) and is based on both the most recent scientific studies on the groundwater field and new survey activities carried out in order to fill the data gaps in several areas of the examined territory. The

Attention U-Net as a surrogate model for groundwater prediction [PDF]
Advances in Water Resources, Volume 163, May 2022, 104169, 2022 Numerical simulations of groundwater flow are used to analyze and predict the response of an aquifer system to its change in state by approximating the solution of the fundamental groundwater physical equations. The most used and classical methodologies, such as Finite Difference (FD) and Finite Element (FE) Methods, use iterative solvers which are ...

Asymmetric impact of groundwater use on groundwater droughts [PDF]
Hydrology and Earth System Sciences, 2020 Abstract. Groundwater use affects groundwater storage continuously, as the removal of water changes both short-term and long-term variation in groundwater level. This has implications for groundwater droughts, i.e. a below-normal groundwater level. The impact of groundwater use on groundwater droughts remains unknown. Hence, the aim of this study is to

Groundwater flood or groundwater-induced flood? [PDF]
Quarterly Journal of Engineering Geology and Hydrogeology, 2012 A number of ‘groundwater flood’ events have been recorded over the Chalk aquifer in southern England since the 1994 occurrence at Chichester, Sussex. Reporting of this event and subsequent groundwater floods indicates that there are two types of groundwater flood event. Type 1 is the true groundwater flood in which the water table elevation rises above

Impacts of climate change on groundwater droughts by means of standardized indices and regional climate models [PDF]
Journal of Hydrology 603 (2021) 127154, 2022 This paper investigates the impacts of climate change on groundwater droughts making use of regional projections and standardized indices: the Standardized Precipitation Index (SPI), the Standardized Precipitation Evapotranspiration Index (SPEI) and the Standardized Groundwater Index (SGI).

Experimental study of time series forecasting methods for groundwater level prediction [PDF]
ECML/PKDD Workshop on Advanced Analytics and Learning on Temporal
Data, Sep 2022, Grenoble, France. pp.1-16, 2022 Groundwater level prediction is an applied time series forecasting task with important social impacts to optimize water management as well as preventing some natural disasters: for instance, floods or severe droughts. Machine learning methods have been reported in the literature to achieve this task, but they are only focused on the forecast of the ...

The Relationship Between Groundwater Nitrate Pollution and Crime in United States: Nitrate-Crime Hypothesis [PDF]
arXiv, 2023 Groundwater is a crucial source of drinking water, but it is often contaminated with water-soluble pollutants that can pose significant health risks. Among these pollutants, nitrate has been extensively studied and found to be harmful to human health in high concentrations.
