Rehabilitation of the South Jetty, Ocean City, Maryland

Description: Partial abstract: Frequent dredging requirements and scouring at the foundation of Ocean City Inlet's south jetty resulted in a study to determine the source of the shoaling and scouring. The study concluded that sand was being transported northward along Assateague Island, through and over the south jetty, and deposited inside the inlet. The sand was then transported north by ebb currents where it encroached on the Federal navigation channel. A rehabilitation program was initiated to create a … more

Landslides in Colluvium

Description: From introduction: This report describes the Delhi Pike area, which is an area of landsliding we believe to be representative of landslides in colluvium throughout the Cincinnati metropolitan area. The area has been the focus of several detailed studies reported in other chapters in this bulletin. The purpose of the report is to describe the physical setting and movement styles of the landslides and, thus, to provide a context for the more narrowly focused chapters that follow.

Coal Reserves of the Boltsfork Quadrangle, Kentucky: A Coal Recoverability Study

Description: Abstract: "This report presents a U.S. Bureau of Mines study that incorporates coal mining factors, cola recovery factors, and economic factors into the definition of an economically recoverable coal resource. The relationship between these factors to the Energy Information Administration's estimate of U.S. coal resources--the "Demonstrated Reserve Base"--is discussed. The Boltsfork 7 1/2-minute quadrangle in eastern Kentucky was selected as the stud area. Results indicate that of the origi… more
