Assessing the Periodic Groundwater Flow Conditions of a Perched Aquifer System in the Daniel Boone National Forest

Ethan Sweet and Jonathan Malzone

Eastern Kentucky University, Department of Geosciences

Natural ephemeral wetlands situated among the ridge-tops in the Daniel Boone National Forest serve as reservoirs that recharge a shallow groundwater system. Unique interactions between surface and groundwater in these isolated systems provide substantial support for the native ecosystem, serving as a breeding ground for amphibians and as source water for vegetation—especially in periods of drought. Currently it is not understood how groundwater could provide regional biodiversity, a drought buffer, or a …

Abstract

Cropping practices leading to loss of soil organic matter thus can alter other soil properties. The purpose of this study was to determine the impact of crop and non-crop areas on soils. Disturbed and undisturbed soil samples were collected from different fields of corn, soybeans, tobacco, pasture, and wooded areas in the Southwest portion of Calloway County, Kentucky on September 8, 2017. The properties observed …

Vegetation Habitat Mapping Of Mammoth Cave National Park Using Multi-Date Landsat-8 Imagery And Lidar Data, Hongli Yang

Steeplechase: An ORCA Student Journal

Vegetation habitat mapping can be regarded as a model predicting the geographic distribution of plant cover types from mapped environmental variables. This paper discusses three environmental factors- slope, aspect and bedrock geology that determined different habitat types in Mammoth Cave National Park. The variation of aspect and slope can largely determine the amount of solar radiation and water available to vegetation, which influences the contrasting habitat types formed in a long term. Bedrock geology, one of the most influential factor in the study area, primarily controls the soil types and drainage conditions that support the various habitat types. The habitat …

Habitat Modeling And Vegetation Mapping Of Mammoth Cave National Park Using Lidar Data And Multispectral Imagery, Hongli Yang

Murray State Theses and Dissertations

An up-to-date and detailed vegetation map provides critical information for habitat management. In addition, a habitat model is necessary for Park’s Fire Management, for classification of fuel types, and for delineation of fire management units. Several attempts to map the vegetation at the Mammoth Cave National Park were conducted in 1934, 1975, 1997 and 2011. This essential goal of this study was to produce a new vegetation habitat model and update the vegetation map for the Park. Landsat-8 Operational Land Imager (OLI) imagery, LiDAR and bedrock dataset were used for habitat model configuration and vegetation mapping at Mammoth Cave National …
