Crumps Cave is located about one kilometer northeast of Smiths Grove, Kentucky (Figures 1, 2, and 3). The only known entrance was purchased by Western Kentucky University (WKU) in 2009 through a grant from the Kentucky Heritage Land Conservation Fund and the cave is managed as the focal point of a research and education preserve to study a wide range of environmental conditions and dynamics, and their interactions, using high-resolution electronic monitoring along with geochemical sampling, analysis and modeling. Crews from WKU’s Hoffman Environmental Research Institute visit the cave weekly for sampling, data downloading, and equipment maintenance, with a major …
Climate Data Manipulation And The Use Of Water To Build Political Power In The Southwest United States, Conrad Moore, Professor Emeritus
Climate Data Manipulation And The Use Of Water To Build Political Power In The Southwest United States, Conrad Moore, Professor Emeritus
Earth, Environmental, and Atmospheric Sciences Faculty Publications
Models utilized by the Intergovernmental Panel on Climate Change indicate a striking trend toward increasing aridity in the Southwest United States. Two landmark articles published in Science magazine have emphasized the critical future consequences of this trend. Data from 59 National Weather Service stations distributed across the region west of the continental divide and south of the 41stparallel (the northern border of Colorado and northeastern Utah), including 36 stations in the Upper Colorado River Basin and lower Southwest, show that annual and winter precipitation increased over the 60-year period 1950-2010, although the record is impoverished by the deletion …

Belize is a developing country that faces water resource issues in the forms of both quality and quantity, stemming from a long history of environmental stress and population threats, from the ancient Maya to present. Belize’s karst landscape, which comprises a large part of the country from the coast to the Maya Mountains, is characterized by springs, caves, sinkholes, and aquifers systems formed from the dissolution of carbonate (limestone, dolomite) rock. This research presents several different case studies, spanning from the ancient Maya and issues with drought to modern communities that rely on groundwater resources quickly being depleted. Past drought …

Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan
Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan
Earth, Environmental, and Atmospheric Sciences Faculty Publications
A standard planar Kernel Density Estimation (KDE) aims to produce a smooth density surface of spatial point events over a 2-D geographic space. However, the planar KDE may not be suited for characterizing certain point events, such as traffic accidents, which usually occur inside a 1-D linear space, the roadway network. This paper presents a novel network KDE approach to estimating the density of such spatial point events. One key feature of the new approach is that the network space is represented with basic linear units of equal network length, termed lixel (linear pixel), and related network topology. The use …

High-resolution measurements of rainfall, water level, pH, conductivity, temperature and carbonate chemistry parameters of groundwater at two adjacent locations within the peak cluster karst of the Guilin Karst Experimental Site in Guangxi Province, China, were made with different types of multiparameter sonde. The data were stored using data loggers recording with 2 min or 15 min resolution. Waters from a large, perennial spring represent the exit for the aquifer's conduit flow, and a nearby well measures water in the conduit-adjacent, fractured media. During flood pulses, the pH of the conduit flow water rises as the conductivity falls. In contrast, and …
In-Cave Dye Tracing And Drainage Basin Divides In The Mammoth Cave Karst Aquifer, Kentucky, Chris Groves, Joe Meiman, Shannon Herstein
In-Cave Dye Tracing And Drainage Basin Divides In The Mammoth Cave Karst Aquifer, Kentucky, Chris Groves, Joe Meiman, Shannon Herstein
Earth, Environmental, and Atmospheric Sciences Faculty Publications
Karst ground-water basin divides are generally depicted as two-dimensional lines on maps, but they are better considered as three-dimensional surfaces within the subsurface. Dye traces are necessary to map out these surfaces and to locate conduits inaccessible to cave surveyors, and are indispensable for understanding the geometry of the complex networks of flow paths through the aquifer. A key reason why the Mammoth Cave System is the world's longest known cave is that its passages extend over several major ground-water basins. The divides between these basins define the drainage system geometry and precise location of them is critical for understanding …
