Evaluation Of First Order Error Induced By Conservative-Tracer Temperature Approximation For Mixing In Karstic Flow, Philippe Machetel, David A. Yuen Oct 2015

Evaluation Of First Order Error Induced By Conservative-Tracer Temperature Approximation For Mixing In Karstic Flow, Philippe Machetel, David A. Yuen

Sinkhole Conference 2015

Fluid dynamics in karst systems is complex due to the heterogeneity of hydraulic networks that combine the Porous Fractured Matrix (PFM) and the interconnected drains (CS). These complex dynamic systems often need to be treated as “black boxes” in which only input and output properties are known. In this work, we propose to assess the first-order error induced by considering the temperature as a conservative tracer for flows mixing in karst (fluvio-karst). The fluvio-karstic system is treated as an open thermodynamic system (OTS), which exchanges water and heat with its surrounding. We propose to use a cylindrical PFM drained by …


Numerical Simulation Of Spring Hydrograph Recession Curves For East Yorkshire Chalk Aquifer, Uk, Nozad Hasan Azeez, Landis Jared West, Simon H. Bottrell Oct 2015

Numerical Simulation Of Spring Hydrograph Recession Curves For East Yorkshire Chalk Aquifer, Uk, Nozad Hasan Azeez, Landis Jared West, Simon H. Bottrell

Sinkhole Conference 2015

The Cretaceous Chalk aquifer is the most important in the UK for the provision of water to public supply and agriculture. The Chalk has both matrix and fracture porosity and is thus best considered as a dual porosity aquifer system. Although the matrix porosity is large, typically around 0.35 in the study area of East Yorkshire, UK (ESI, 2010), pore diameters are typically very small, and the water contained in them is virtually immobile. The high permeability fracture network is responsible for the ability of water to drain; spatial variations in fracture network properties mean conventional approaches to aquifer characterization …


Accounting For Anomalous Hydraulic Responses During Constant-Rate Pumping Tests In The Prairie Du Chien-Jordan Aquifer System – Towards A More Accurate Assessment Of Leakage, Justin Blum Oct 2015

Accounting For Anomalous Hydraulic Responses During Constant-Rate Pumping Tests In The Prairie Du Chien-Jordan Aquifer System – Towards A More Accurate Assessment Of Leakage, Justin Blum

Sinkhole Conference 2015

The Prairie du Chien-Jordan Aquifer system is an important source of drinking water for residents of southeastern Minnesota. Assessment of the hydraulic properties of this aquifer continues to be of interest for wellhead protection and resource evaluation efforts. When performing constant-rate pumping tests on wells constructed in the karsted Prairie du Chien Aquifer, anomalous hydraulic responses resulting from cavernous flow are frequently observed. Hydraulic response in the adjacent Jordan Sandstone Aquifer is also commonly distorted because of bedding-plane fractures and well development techniques such as blasting and bailing. Resolution of these anomalous responses is important for accurate estimates of leakage …


Hydrochemical Characteristics And Formation Mechanism Of Groundwater In The Liulin Karst System, Min Yang, Feng'e Zhang, Sheng Zhang, Miying Yin, Guoqing Wu Oct 2015

Hydrochemical Characteristics And Formation Mechanism Of Groundwater In The Liulin Karst System, Min Yang, Feng'e Zhang, Sheng Zhang, Miying Yin, Guoqing Wu

Sinkhole Conference 2015

The Liulin karst system is typical of hydrogeological systems in northwestern China, with a group of springs as the dominant mechanism for regional groundwater discharge. To reveal the hydrochemical formation mechanism of the Liulin karst groundwater system, we studied the hydrogeochemical processes of karst groundwater in aquifers at the base of the hydrogeological investigation. Then starting from the chemical composition of karst groundwater together with the recharge-runoff - discharge process of groundwater systems, we analyzed the solutes origin and the dissolved mineral facies of the groundwater chemical composition. The results showed that the anionic and cationic compositions of karst water …


Dye Tracing Through The Vadose Zone Above Wind Cave, Custer County, South Dakota, James Nepstad Oct 2015

Dye Tracing Through The Vadose Zone Above Wind Cave, Custer County, South Dakota, James Nepstad

Sinkhole Conference 2015

During the 1990s, in an attempt to better understand threats posed by surface developments overlying the cave, National Park Service staff at Wind Cave National Park in Custer County, South Dakota carried out a series of dye traces through portions of the vadose zone overlying the cave. Wind Cave is located within the 100m-thick Madison formation (limestone and dolomite), which in most locations is capped by varying thicknesses of the basal units of the Minnelusa formation (intermingled beds of sandstone, limestone, and shale). A variety of cave locations with dripping or pooled water were monitored for up to five years …


Finding Springs In The File Cabinet, Mason Johnson, Ashley Ignatius Oct 2015

Finding Springs In The File Cabinet, Mason Johnson, Ashley Ignatius

Sinkhole Conference 2015

The Minnesota Pollution Control Agency (MPCA), in partnership with other agencies, is currently undertaking comprehensive sub-basin assessments statewide over a ten-year period. Southeast Minnesota has over 17,500 kilometers of perennial and intermittent streams, making the task of comprehensive sub-basin assessment challenging; the task is further complicated by karst geology. In the summer of 2014, a pilot project began between the MPCA and Minnesota Department of Natural Resources (DNR) to digitally preserve paper documents which capture qualitative and quantitative data about the hydrology, water chemistry, geomorphology, biology, land use and karst features of southeast Minnesota streams. The paper documents in file …


Legacy Data In The Minnesota Spring Inventory, Greg Brick Oct 2015

Legacy Data In The Minnesota Spring Inventory, Greg Brick

Sinkhole Conference 2015

Past spring inventories have covered certain parts of Minnesota reasonably well, notably, the springs of the Minneapolis-St. Paul metropolitan area and the southeastern Minnesota karst. But hitherto, there has not been a systematic effort to create a uniform statewide inventory. The first step, before hunting down new springs, was to compile existing data and the most fruitful source of hydrological legacy data for the Minnesota spring inventory was the DNR Fisheries files. Once entered into a GIS-capable database, these spring locations can help “seed the ground” so that when crews finally do take to the field to map more springs, …


History And Future Of The Minnesota Karst Feature Database, Robert Tipping, Mathew Rantala, E. Calvin Alexander Jr., Yongli Gao, Jeffrey Green Oct 2015

History And Future Of The Minnesota Karst Feature Database, Robert Tipping, Mathew Rantala, E. Calvin Alexander Jr., Yongli Gao, Jeffrey Green

Sinkhole Conference 2015

Since the 1990s, the University of Minnesota and the Minnesota Department of Natural Resources have maintained a karst features database that is used to conduct research on karst processes and inventory karst features. Originally designed as a tabular database only, the karst features database developed into a spatial database in 2002, with tabular data stored in Microsoft Access and a spatial component managed in ESRI ArcView. In 2012, the database was converted to a single, relational database platform, PostgreSQL, with both tabular and spatial components edited in ESRI ArcMap. Custom editing forms are written in Visual Basic and are accessed …


Sinkhole Vulnerability Mapping: Results From A Pilot Study In North Central Florida, Clint Kromhout, Alan E. Baker Oct 2015

Sinkhole Vulnerability Mapping: Results From A Pilot Study In North Central Florida, Clint Kromhout, Alan E. Baker

Sinkhole Conference 2015

At the end of June in 2012, Tropical Storm Debby dropped a record amount of rainfall across Florida which triggered hundreds, if not thousands, of sinkholes to form which resulted in tremendous damage to property. The Florida Division of Emergency Management contracted with the Florida Department of Environmental Protection’s Florida Geological Survey to produce a map depicting the state’s vulnerability to sinkhole formation. The three-year project began with a pilot study in three northern Florida counties: Columbia, Hamilton and Suwannee. Utilizing the statistical modeling method Weights of Evidence, results from the pilot study yielded a 93 percent success rate of …


Shallow Depressions In The Florida Coastal Plain: Karst And Pseudokarst, Sam B. Upchurch, Thomas M. Scott, Michael C. Alfieri, Thomas L. Dobecki Oct 2015

Shallow Depressions In The Florida Coastal Plain: Karst And Pseudokarst, Sam B. Upchurch, Thomas M. Scott, Michael C. Alfieri, Thomas L. Dobecki

Sinkhole Conference 2015

In Florida, shallow depressions (i.e., depressions <1-2 m in depth) on the land surface are often attributed to sinkhole development. However, it has become evident that there are at least six different mechanisms through which these depressions can form in geologically young cover sediments. These mechanisms include: 1. Cover-subsidence sinkholes over shallow limestone; 2. Suffosion sinkholes over shallow limestone; 3. Cover settlement over shallow shell beds; 4. Large, aeolian deflation areas that resemble “Carolina bays;” 5. Depressions that mimic landforms developed on a shallow paleosol; and 6. Depressions created by pedodiagenesis (i.e., conversion of smectite to kaolinite) in a soil-forming environment. Of these, only the first two appear to represent traditional mechanisms for sinkhole development in eogenetic karst. Cover settlement over shell beds is poorly understood and incorrectly attributed to sinkhole development processes. This type of depression has serious limitations in terms of cover thickness and shell content of the substrate. The last three mechanisms are pseudokarst created by aeolian and soil-forming processes. In this paper we present examples of each and discuss their constraints and evidence.


Creation Of A Map Of Paleozoic Bedrock Springsheds In Southeast Minnesota, Jeffrey A. Green, E. Calvin Alexander Jr. Oct 2015

Creation Of A Map Of Paleozoic Bedrock Springsheds In Southeast Minnesota, Jeffrey A. Green, E. Calvin Alexander Jr.

Sinkhole Conference 2015

Springs are groundwater discharge points that serve as vital coldwater sources for streams in southeast Minnesota. The springs generally emanate from Paleozoic carbonate and siliciclastic bedrock aquifers. Use of systematic dye tracing began in the 1970s and continues through the present as a standard method for investigating karst hydrology and to map springsheds,. The work was accelerated in 2007 because of increased funding from the State of Minnesota’s Environment and Natural Resources Trust Fund. A compilation springshed map of dye traces conducted over the last several decades has been assembled for the region. In southeast Minnesota, the springs are the …


Investigation Of A Sinkhole In Ogle County, Northwestern Illinois, Using Near-Surface Geophysical Techniques, Philip J. Carpenter, Lauren Schroeder Oct 2015

Investigation Of A Sinkhole In Ogle County, Northwestern Illinois, Using Near-Surface Geophysical Techniques, Philip J. Carpenter, Lauren Schroeder

Sinkhole Conference 2015

A sinkhole measuring 40 m in diameter and up to 6.5 m deep occurs within the Nachusa Grasslands, near the town of Franklin Grove, northwestern Illinois. This area, dedicated to prairie conservation and restoration, is owned and operated by The Nature Conservancy. Several meters of unconsolidated sand, gravel, and clay overlie the St. Peter sandstone, beneath which lies karstic Prairie du Chien dolomite. Investigations included EM conductivity profiles, resistivity soundings, 2D resistivity, and ground- penetrating radar (GPR), supplemented by conductivity logs, soil cores, and tree core studies. These data indicate the sandstone averages about 5 m deep near the sinkhole …


Goliath’S Cave, Minnesota: Epigenic Modification And Extension Of Pre-Existing Hypogenic Conduits, E. Calvin Alexander Jr., Scott C. Alexander, Kelton Barr, Andrew Luhmann, Cale Anger Oct 2015

Goliath’S Cave, Minnesota: Epigenic Modification And Extension Of Pre-Existing Hypogenic Conduits, E. Calvin Alexander Jr., Scott C. Alexander, Kelton Barr, Andrew Luhmann, Cale Anger

Sinkhole Conference 2015

Goliath’s Cave is developed in the Ordovician Dubuque and Stewartville Formations of the Galena Group in Fillmore County, MN. The cave currently functions as an epigenic karst system with allogenic surface water sinking into the cave and a vadose stream running through the cave and resurging at springs a few kilometers away. Passages in the cave are locally controlled by vertical joints in the nearly flat-lying carbonate bedrock, but the water flow directions often do not correspond to the systematic joint directions. The cave contains straight, joint-controlled passages that appear to pre-date the current epigenic drainage systems. These old passages …


Relay Ramp Structures And Their Influence On Groundwater Flow In The Edwards And Trinity Aquifers, Hays And Travis Counties, Central Texas, Brian B. Hunt, Brian A. Smith, Alan Andrews, Douglas Wierman, Alex S. Broun, Marcus Gary Oct 2015

Relay Ramp Structures And Their Influence On Groundwater Flow In The Edwards And Trinity Aquifers, Hays And Travis Counties, Central Texas, Brian B. Hunt, Brian A. Smith, Alan Andrews, Douglas Wierman, Alex S. Broun, Marcus Gary

Sinkhole Conference 2015

The Cretaceous Edwards and Middle Trinity Aquifers of central Texas are critical groundwater resources for human and ecological needs. These two major karst aquifers are stratigraphically stacked (Edwards over Trinity) and structurally juxtaposed (normal faulting) in the Balcones Fault Zone (BFZ). Studies have long recognized the importance of faulting on the development of the karstic Edwards Aquifer. However, the influence of these structures on groundwater flow is unclear as groundwater flow appears to cross some faults, but not others. This study combines structural and hydrological data to help characterize the potential influence of faults and relay ramps on groundwater flow …


The Sandstone Karst Of Pine County, Minnesota, Beverley Lynn Shade, Emmit Calvin Alexander Jr., Scott C. Alexander Oct 2015

The Sandstone Karst Of Pine County, Minnesota, Beverley Lynn Shade, Emmit Calvin Alexander Jr., Scott C. Alexander

Sinkhole Conference 2015

The glaciated, forested landscape of central Pine County in east-central Minnesota contains a series of sinkholes, stream sinks, springs and caves. The features are formed in Precambrian Hinckley Sandstone and overlying unconsolidated glacial deposits. This is a sandstone karst. The features serve the same function as in carbonate karst terrains: sinkholes and caves focus recharge into a heterogeneous subterranean flow system that discharges into springs. The Hinckley Sandstone is a quartz arenite. No carbonate grains or cements have been found in sandstone samples from the sinkhole area, nor is there evidence that calcite solution controls bedrock permeability. Three parameters appear …


Determination Of The Relationship Of Nitrate To Discharge And Flow Systems In North Florida Springs, Sam B. Upchurch Oct 2015

Determination Of The Relationship Of Nitrate To Discharge And Flow Systems In North Florida Springs, Sam B. Upchurch

Sinkhole Conference 2015

The Suwannee River Water Management District has collected quarterly discharge and water quality data from 30 1st and 2nd magnitude springs in the Suwannee River Basin since 1998. These data were collected quarterly well into the late 2000s and constitute a valuable database for characterizing spring discharge behavior. Trend and correlation analyses were used to compare the relationships of NO3- + NO2- (nitrate in this paper), specific conductance, and spring discharge. Trends were considered significant if alpha levels of the trend slopes were ≤ 0.05. Data from 50% of the springs show that nitrate concentrations increase as discharge from the …
