Download or read book Highway Runoff in Areas of Karst Topography written by Bridget M. Donaldson and published by . This book was released on 2004 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Karst terrain is characterized by sinkholes, depressions, caves, and underground drainage, generally underlain by soluble rocks such as limestone and dolomite. Because natural filtration through soil is limited in karst areas, pollutants in highway stormwater runoff can directly infiltrate underground sources of drinking water and environments that are habitats for sensitive species. Although the Virginia Department of Transportation (VDOT) has implemented guidelines for construction projects in karst areas to ameliorate this problem, there has been considerable activity at the state level in recent years concerning the protection of karst groundwater. New regulations or requirements regarding karst area runoff could add significantly to VDOT's construction and maintenance activities. This report summarizes the research and regulations to position VDOT to manage karst topography issues appropriately. Although more studies of karst groundwater contamination are needed, the literature does not currently support the need for more stringent regulatory controls than are already in place.

Download or read book Remediation of Roadway Runoff Nutrients written by Mohammad Shokri and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stormwater road runoff is a widespread non-point source of contaminants such as nutrients, which endangers water bodies, especially in vulnerable karst areas such as Florida. While roadside vegetated filter strips (VFSs) and stormwater basins are generally accepted best management practices (BMPs) for stormwater management, uncertainties about VFS nutrient removal are reported and stormwater basins are concerned of facilitating contaminant transport. In this dissertation, the application and efficacy of engineered infiltration media was tested as a subgrade for the enhanced nutrient removal from roadway runoff. Results of field-scale laboratory testing indicated that a VFS with engineered biosorption activated media (BAM) outperformed a Control with sandy soil concerning nitrate removal (mean 94±6% reduction vs. 23±64% increase) and total nitrogen removal (mean 80±5% vs. 38±23% reduction) within a 6 m filter width. However, BAM and soil performed similarly with respected to total phosphorus removal within the first 1.5 m filter width (84±9% vs. 82±12% reduction). Next, field sampling was conducted to characterize nutrient load and delivery in stormwater road runoff in different events, providing insights to improve design of BMPs. Three types of runoff events were characterized, where nutrients are transported differently under the controls of nutrient supply and transport conditions. Antecedent dry period was strongly related to nutrient supply and runoff volume was correlated to nutrient transport capacity. Finally, the configuration of the subsurface in stormwater basins and runoff movement to and within karst aquifer near Silver Springs in central Florida were investigated using geophysical surveys (ground penetrating radar and frequency domain electromagnetics) and tracer tests. Numerous subsurface anomalies and surface sinkholes were detected in the basins. High groundwater velocities in the surficial aquifer (10−6 to 10−3 ms−1) and Upper Floridan Aquifer (maximum on the order of 10−1 ms−1) indicated that the basins act as hotspots of groundwater contamination in the area.

Book excerpt: Geologists and geographers study how to develop how and where karst develops and how sinkholes form, but engineers must use this information to develop karst terrane. Over the past ten years, these multidisciplinary conferences on the applied aspects of karst hydrogeology and engineering have been successful in bringing together engineers, geologists, other scientists and government regulators who must safely establish human infrastructure on karst terrane whilst protecting the environment. The essences of these conferences has always been communciation between geologists and engineers with an emplasis on practical applications and case studies. This text contains the proceedings of the fifth conference on karst geohazards. It presents 65 papers that cover topics such as: groundwater contamination through sinkholes and the karst surface; stormwater drainage and flooding problems; and foundation considerations and improvements in karst.

Download or read book Atlas of Karst Collapses written by Mingtang Lei and published by Springer Nature. This book was released on 2022-01-19 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively documents the various types of karst collapse and related conceptual site models, before discussing these collapses in terms of their impacts on engineering and the environment. Featuring over 200 real-world photos to illustrate the variety of karst collapses and their consequences, the book also provides specific methods and techniques to prevent, investigate, monitor and remediate these collapses. Decades of experience with these collapses make it clear that addressing the related hazards requires a multi-disciplinary approach that integrates geomorphology, engineering geology, hydrology, hydrogeology, biology, geophysics, geochemistry, and risk assessment.

Available in PDF, EPUB and Kindle. Book excerpt: "Sinkholes and Subsidence" provides a twenty-first century account of how the various subsidence features in carbonate and evaporite rocks cause problems in development and construction in our living environment. The authors explain the processes by which different types of sinkholes develop and mature in karst terrains. They consider the various methods used in site investigations, both direct and indirect, to locate the features associated with these hazards and risks, highlighting the value of hazard mapping. Various ground improvement techniques and the special types of foundation structures which deal with these problems are covered in the second half of the text. This book is supplemented with a wealth of actual case studies and solutions, written by invited experts.

Download or read book Karst Hydrogeology and Human Activities Impacts Consequences and Implications written by David Drew and published by Routledge. This book was released on 2017-10-05 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: One quarter of the world's population lives in karst terrains, yet karsts are highly vulnerable to stresses caused by human activity. This book surveys human impact on karst water, showing that the increasing pollution of the environment has, to a great extent, spoiled sensitive karst ecosystems. This text examines such consequences and offers proposals for future solutions and strategies. Part One provides an overview of the functioning of karsts and of human interaction with karst environments over several millennia. Part Two consists of a systematic examination of the major areas of human activity affecting karst waters, such as agriculture, industry, mining and water exploitation. Finally, Part Three views the effects on karst groundwater within a broader societal and legislative perspective and considers possible changes of methodology and approach.
