Hellenic Karst Aquifers Vulnerability Approach Using Factor Analysis: The Example of the Louros Karst Aquifers [PDF]

Geosciences, 2018
The karst aquifers of the Hellenic territory display high vulnerability that is related to the existence of the epikarst zone. If present, the epikarst zone regulates the vertical movement of the groundwater, which results in the chemical pollutants staying longer within it, thus facilitating the inactivation of the microbial loads.

Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

World Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Application of an improved distributed Xinanjiang hydrological model for flood prediction in a karst catchment in South‐Western China

Journal of Flood Risk Management, 2020
Hydrological processes in karst aquifer systems are controlled by highly permeable media, so studying flood processes in karst‐dominated regions is very important; however, it is still a challenge to model the hydrological dynamics in such strongly ...

Time series analysis, modelling and assessment of optimal exploitation of the Nemanja karst springs, Serbia

Acta Carsologica, 2010
The time series analysis was applied in the case-study of a karst aquifer in Serbia in order to study its functioning, hydrody­namic behavior and hydraulic properties. Focusing on the defi­nition of groundwater budget, due to very complex function­ing of

Managed aquifer recharge and extraction effects on groundwater level and quality dynamics in a typical temperate semi-arid fissured karst system: a multi-method quantitative study [PDF]

Hydrology and Earth System Sciences
Managed aquifer recharge (MAR) is an effective approach to mitigate groundwater decline and spring depletion in karst systems impacted by excessive exploitation.

Tracking flowpaths in a complex karst system through tracer test and hydrogeochemical monitoring: Implications for groundwater protection (Gran Sasso, Italy)

Heliyon
Groundwater in karst aquifers is frequently tapped for drinking purposes, due to frequent huge volumes of resources. Unfortunately, vulnerability of these aquifers can be high, due to possible fast transfer of recharge water on springs by the karst ...

Zoning of early warning for karst collapses in the Jingquan area of Shandong Province

Carsologica Sinica
As one of the most common geological disasters in the Jingquan area, covered karst collapses mostly occurred in the dry seasons from 2015 to 2017. With the frequent occurrence of karst collapses, the sustainable development of economy and the safety of ...
