Study on the Sustainable use of Regional Groundwater Resources [PDF]

open access: yesE3S Web of Conferences, 2023
Water resources have become a major factor limiting the sustainable development of China’s economy and society, and at the same time China’s water resources are developed and utilized in a relatively sloppy manner, China is facing multiple pressures of ...

Groundwater of Rome [PDF]

open access: yesJournal 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

Method for indirect determination of soil parameters for numerical simulation of dikes and earth dams

open access: yesApplied Water Science, 2022
One of the most important steps in the numerical simulation of a hydrogeological system is the precise definition of initial and boundary conditions. The better these are characterized, the more efficient the calculation and the more accurate are the ...

Resolution-Dependent Multifractal Characteristics of Flow in Digital Rock Twin Simulated Using the Lattice Boltzmann Method

open access: yesGeofluids, 2023
Digital rock twins are widely used to obtain hydraulic properties of porous media by simulating pore-scale fluid flow. Multifractal characteristics of pore geometry and flow velocity distribution have been discovered with two-dimensional (2D) images and ...

Purification Efficiency for Treated Waste Water in Case of Joint Infiltration with Water Originating from Precipitation

open access: yesApplied Sciences, 2020
The decentralized treatment of wastewater and its on-site infiltration is common practice, especially in rural areas. However, uncertainties exist on the degradation potential of treated wastewater constituents mixed with additional infiltration of large

Asymmetric impact of groundwater use on groundwater droughts [PDF]

open access: yesHydrology 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

Optimal location of cutoff walls for seawater intrusion

open access: yesApplied Water Science, 2021
In this paper, the simulation–optimization method is used to study the optimal location of cutoff walls for seawater intrusion. The optimization model is based on minimizing the chlorine concentration of two water sources after 50 years.
