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

State-of-the-Art for Assessing Earthquake Hazards in the United States, Report 28: Recommended Accelerograms for Earthquake Ground Motions

Description: Abstract: "A catalog of recommended accelerograms and response spectra is provided to accompany all representative values for Richter magnitudes at distance determined peak horizontal accelerations-velocities-durations, hard and soft sites, shallow and deep earthquakes. Accelerograms are also recommended for corresponding Modified Mercalli intensities. The accelerograms are related to the Krinitzsky-Chang-Nuttli curves for magnitude and distance, and the Krinitzsky-Chang curves for MM intensity… more

Concepts for Installation of the Precast Concrete Stay-in-Place Forming System for Lock Wall Rehabilitation in an Operational Lock

Description: Report describing a study to extend the application of a method to rehabilitate damaged lock walls that uses a stay-in-place forming system. "During this study, operational and design criteria were developed to serve as the basis for design. A number of repair concepts were identified that satisfied the criteria" (abstract, para. 3).

Levee Underseepage Analysis for Special Foundation Conditions

Description: This report describes a research study in which techniques were developed for prediction of underseepage conditions for special cases of levee and foundation geometry. The differential equations for levee underseepage were derived and programmed in finite difference form for three special cases of boundary conditions. The developed programs allow analyses that are not restricted to the boundary conditions assumed in the conventional, closed form solution, i.e., two foundation layers of uniform … more

Levee Underseepage Software: User Manual and Validation

Description: Report discussing the FORTRAN 77 computer program (LEVSEEP), developed to analyze levee underseepage on IBM PC compatible microcomputers with an 8087 math coprocessor. The software and associated equipment plots cross sections and piezometer data; calculates seepage flow and substratum pressure; analyzes landside berm, river side blanket, cutoff and relief well control measures; and finally, estimates the construction cost of these alternatives.
