Overview Researchers from Crawford Hydrology Laboratory are conducting dye tracing studies of the Great Onyx Basin in Mammoth Cave National Park, Kentucky, to enhance our understanding of karst hydrogeology and lay the groundwork for future studies on sustainable practices in the park and the role of karst landscapes in the carbon cycle. Challenge Extensive ...
Overview The Karst Research Institute, part of the Scientific Research Centre of the Slovenian Academy of Sciences and Arts, uses a variety of In-Situ equipment to continuously monitor several caves within the country’s vast, complex network of karst aquifers. ...
Following a 3.2 magnitude earthquake on September 7th, the water level of the karst river Vrljika started dropping very quickly. This rare phenomenon has last occurred in 2004, and, before that, in 1942. ...
Earth Scan was asked to help define a large plunging karst feature in a large open pit gold mine. The karst tube had collapsed and represented a potential hazard to mine excavations. ...
The groundwater flow in the vicinity is mainly controlled by regional dykes and faults in a karst aquifer. A 3-D groundwater model was used to simulate the unique geologic setting for water management and dewatering strategies at the ...
Project Details Fremont Raw Water Storage Reservoir Location Fremont, Ohio Products Used BENTOMAT DN BENTOMAT 200R Constructed in 1911, the Ballville Dam serves as the source of water for the city of Fremont, Ohio. It alsoblocks fish movement on the Sandusky River, preventing walleye access to an important spawning habitat. As a result, the City of Fremont teamed up with the ...

Main goals: Characterize a karst system exploited by springs and wells Characterize the surface karst water connections Results: Well on the Drain Annex System (DAS) Sping on the main karstic Drain (D) Opportunities: Inversion monitoring (estavelle) and dynamic pumping management in karstic systems ...
Magnificent features such as the Grand Canyon in Arizona to Mount Kilimanjaro in Tanzania to Uluru in the Australian outback all shape the terrestrial landscape. Beneath the earth surface, a karst scenery becomes very influential. Karst topography make up the subterranean labyrinths known as caves. The remarkable patterns of stalactites and stalagmites form only ...
Water resources situated in areas with underlying karst geology are particularly vulnerable to fecal pollution. In such vulnerable systems, microbial source tracking (MST) methods are useful tools to elucidate the pathways of both animal and human fecal pollution, leading to more accurate water use risk assessments. ...
One finding was that groundwater recharge estimates for the karst regions of Europe, the Middle East, and North Africa are much higher than previously estimated from current large-scale models. ...
The study focuses on the monitoring of physicochemical parameters and major chemical elements of six springs and wells during two seasons. Waters from the coastal karst aquifer Massif Bokkoya Al-Hoceima were analyzed for their chemical quality, and their state of anthropogenic and/or natural contamination was quantified. ...
To assess the effect of three grid cell properties (size, mean slope of the surface and distance between centre of grid and observation well) on groundwater models' performances, a tropical karst catchment characterized by monsoonal season in Rote Island, Indonesia was selected. ...
Benefit To The Client Mike Wharton & Associates—a group of professional spelunkers—went into the Sting cave and mapped all of the chambers, pathways, and passages, coming to the conclusion that the karst feature was a true interstitial void that housed no biological life. ...
Background Comal Springs, Texas, is home to the self-named springs, which flow from the Edwards Aquifer. The Edwards Aquifer is a karst aquifer that serves the agricultural, industrial, recreational, and domestic needs of almost two million users in south central Texas (source). ...
Studying on regional water carrying capacity is beneficial for the optimal management of water resources, and can provide assistance for the sustainable utilization of water resources. The typical karst area in China – Guizhou province was applied as the research area in the paper. ...
Furthermore, assessment using the enrichment factors (EF), the ratio of secondary to primary phase (RSP) and the secondary phases enrichment factor (SPEF) methods showed that the risk of vanadium in sediments especially from sites TLHJC and TX from Hongfeng Lake was generally high.Keywords: vanadium fractions, karst, risk assessment, surface sediments, China, karstic lakes, trace ...
The district of Gunungkidul on Java Island in Indonesia is affected by an acute water shortage, especially during dry seasons. Because of its karst topography, rainfall percolates rapidly into underground caves, limiting surface storage. ...
The bacteria diversity is complex and decreases from upstream to downstream locations due to dilution with water provided by tributaries or retention of bacteria in the subsurface by adhesion to substrates. We suggest that karst can have a significant potential for natural attenuation by retaining the pollution underground, in combination with biodegradation performed by ...
This paper describes research on two of the largest karst springs in Poland's Tatra Mountains – Goryczkowe and Bystrej Górne – both located in the Tatra National Park. ...
The property presented a series of unique challenges including multiple LNAPL plumes, LNAPL identified within karst bedrock, bedrock fractures impacted with LNAPL with identified impacts over 180-ft below grade, and impacts to private drinking water supplies. ...
