Water flow characteristics of Maocun underground river basin based on environmental isotopes

Carsologica Sinica, 2022
Underground river basins in peak-cluster depressions are main water supply sources of villages in Guangxi. But there exist problems of groundwater exploitation, groundwater pollution and natural disasters in these areas due to a special geological ...

Hydraulic Behavior of Karst Aquifers

Water, 2019
The objective of this Special Issue, “Hydraulic Behavior of Karst Aquifers”, is to focus on recent advances in karst hydrogeology in different areas of the world, focusing on topics dealing with the peculiar characteristics of karst aquifers. In particular, thirteen peer-reviewed articles were collected, focusing on hydraulic aspects and their ...

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Karst Aquifers Vulnerability or Sensitivity?

Acta Carsologica, 2016
Za določitev vodovarstvenih območij ter za načrtovanje rabe prostora v zaledju zajetih kraških izvirov in vrtin se praviloma uporablja koncept kartiranja ranljivosti kraških vodonosnikov. Obstaja več med seboj različnih metodologij kartiranja ranljivosti kraških vodonosnikov in pregled znanstvene literature kaže na določene razlike v definiciji pojma ...

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Numerical karst: Spatio-temporal modelling of karst aquifer systems

, 2014
[EN] The quantitative study of karst aquifers is of great interest due to their enormous importance as water resources and their environmental impact on both the surface and underground.

Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers

Groundwater, EarlyView.
Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...

A Transboundary monitoring network for the management of the Classical karst aquifer.

, 2014
The always increasing demand for good quality freshwater has ancient roots, and when the resource to be protect is a transboundary aquifer, the challenge is quite high, as the case of Classical Karst Reka/Timavo aquifer system, a shared aquifer between ...

Leaky Sewers Hydraulically Disconnect from Groundwater: A Proof‐of‐Concept

Groundwater, EarlyView.
In this study, we newly demonstrate that leaky pipes can become hydraulically disconnected from the underlying groundwater—a phenomenon analogous to river–groundwater interactions. Through numerical modeling, we show that, as the groundwater table declines, the leakage flux from the pipe (in absolute terms) initially increases until a critical depth ...

Tracer Test as a Tool for Optimizing the Flow Patterns and Efficiency of a Full‐Scale Drainage Water Treatment Wetland

Water and Environment Journal, EarlyView.
Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.
