Maya utilization of karst groundwater resources

Environmental Geology and Water Sciences, 1990
Much of the Maya civilization in pre-Columbian Meso-America was established on karst terrain that included parts of what are now Belize, Guatemala, northern Honduras and southern Mexico. By definition, little surface water exists in karst, so for the Maya to flourish on that terrain they had to effectively and efficiently utilize all their water ...

A sinkhole filter for protection of karst groundwater

Journal of Soil and Water Conservation, 2008
P rotection of groundwater quality in karst regions presents land and resource managers with special challenges. About one-quarter of the world's water supply comes from karst sources. Forty percent of the United States east of Tulsa, Oklahoma, is karst.

Investigating microbial pollution in karst groundwater

2023
Many GWSs are well aware of the susceptibility of sources in karst areas to contamination events, including rapid changes to water quality following heavy rainfall. Such changes are difficult to monitor, proving both costly and time-consuming conventional microbiological methods. Hydrogeologist, Luka Vucinic, has been researching alternative monitoring

Karst groundwater: a challenge for new resources

Hydrogeology Journal, 2005
Karst aquifers have complex and original characteristics which make them very different from other aquifers: high heterogeneity created and organised by groundwater flow; large voids, high flow velocities up to several hundreds of m/h, high flow rate springs up to some tens of m3/s.

Management of Groundwater Species in Karst Environments

2011
Carbonate karst is characterized by subterranean drainage and contains the most biodiverse groundwater faunas globally. These faunas, which include a suite of higher taxa largely restricted to karst subterranean waters, comprise species that characteristically are narrow range endemics. They typically possess a suite of adaptations to subterranean life

GROUNDWATER MONITORING NETWORK IN THE CLASSICAL KARST

2012
Classical Karst is a large area located between the North-Eastern part of Italy and the South- Western part of Slovenia. The area runs for about 40 km long and 15 km wide in the SE-NW direction and is bounded on the NW by the Isonzo River valley, on North and NE by the Vipava River valley, on East by the Pivka River basin, on South and SE bordered by ...
