Effects of Alterations to Low Gradient Reaches of Utah Streams

Description: This report describes an investigation of the effects of stream channelization on fish and macro-invertebrates in low gradient reaches of Blacksmith Fork River and the Logan River in the floodplain of Cache Valley in northern Utah.

Development of Nondestructive Testing Systems for in situ Evaluation of Concrete Structures

Description: Final report regarding the testing of concrete structures. Partial abstract: "The need for additional capability to nondestructively evaluate concrete in large structures is similar for both the US Army Corps of Engineers (CE) and the US Bureau of Reclamation (USBR). In view of this mutual need, the CE and the USBR entered into a cooperative program of research and development designed to increase the nondestructive testing evaluation capabilities of these two organizations, with each agency sharing the program planning and financial support."

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 thickness with horizontal boundaries.

Geotechnical Aspects of Rock Erosion in Emergency Spillway Channels, Report 1

Description: "The problem of rock erosion in unlined emergency spillway channels is described in this first-of-a series report. Recent CE and non-CE case histories which illustrate the potentially hazardous impacts of excessive erosion in discharge channels are described as are the various factors controlling erosion and other responses to emergency spillway overflow. Research programs designed to improve geotechnical capabilities with respect to selection of cost-effective preventive and remedial measures in discharge channels where the risk of excessive erosion appears high are also discussed" (abstract, para. 1).

Nondestructive Vibratory Testing and Evaluation Procedure for Military Roads and Streets

Description: This report describes a procedure for the nondestructive evaluation of military roads and streets, performed with the Road Rater 2008 (an electrohydraulic vibrator which measures the load-deflection response of pavements). "[It] also describes the testing equipment, testing techniques, data reduction procedures, and computational methodology used in developing the evaluation procedures. Detailed examples are presented in the Appendices to guide the users through the evaluation procedures for both flexible (AC) and rigid (PCC) highway pavements. An operator's guide describing the day-to-day maintenance and operation of the NODET is presented in Appendix C" (abstract, para. 2).

State-of-the-Art for Assessing Earthquake Hazards in the United States, Report 25: Parameters for Specifying Intensity-Related Earthquake Ground Motions

Description: Abstract: "A set of 12 charts are presented that relate Modified Mercalli intensity units to peak horizontal acceleration, velocity and duration for near field and far field locations, hard and soft sites, and sizes of earthquakes. Also shown is the mean, mean plus one standard deviation, mean plus two standard deviations, and the highest observed values. Ratios are provided of vertical to horizontal motions and predominant periods. These charts are for use with known fault sources and for floating earthquakes in zones where there are no identifiable causative faults. The procedure provides parameters for shaping time histories to be used for dynamic analyses."

Description: Partial abstract: A 1:100-scale (undistorted) hydraulic model, reproducing Mission Bay Harbor, approximately 3 miles of shoreline, and sufficient offshore area to permit generation of the required test waves, was used to investigate the arrangement and design of proposed structures for (a) improving hazardous entrance conditions, (b) reducing surge inside the harbor, and (c) eliminating potential flood hazards. The original proposal for harbor improvement consisted of a 2,200-ft-long offshore breakwater. The proposed structures for river flood control consisted of (a) a 1,200-ft-long weir in the middle jetty, (b) various south jetty extensions, and (c) diversion dikes on the middle jetty.
