Evaluation and management of highway runoff water quality / by Young, G. Kenneth.(CARDINAL)321441; United States.Federal Highway Administration.Office of Environment and Planning.(CARDINAL)321440; GKY & Associates.(CARDINAL)284303;
Includes bibliographical references (pages 445-457).Introduction -- Coordination with environmental agencies and the public -- Highway runoff water quality-- Water quality impact assessment -- Best management practices -- Appendix A -- Bibliography.Final report;The objective of this manual is to gather and to synthesize the results of past documentation and research on highway stormwater runoff into a single-volume user's manual on water quality impact assessment and mitigation. The manual will be useful to highway designers and environmental professionals by presenting the available and appropriate impact prediction and mitigation tools for use during highway project planning and development activities. The development of this document had three components: a literature search on existing research results and operational findings on highway stormwater runoff that identifies existing water quality impact assessment and mitigation techniques; interviews with highway practitioners concerning the use of research results including maintenance of mitigation measures; and synthesis of the accumulated information into this single-volume, practical guidance manual. This manual is intended to be a self-contained desk reference for highway practitioners. An extensive bibliography is included, and the mathematical nomenclature is unified among the sections.Performed by GKY and Associates, Inc., for Office of Environment and Planning, HEP-40, FHWA, under contract no.

Stream stability at highway structures / by Lagasse, Peter F.(Peter Frederick),1937-(CARDINAL)327627; United States.Federal Highway Administration.(CARDINAL)139839; Ayres Associates.(CARDINAL)328982;
Includes bibliographical references (pages 131-134)."This document provides guidelines for identifying stream instability problems at highway stream crossings and for the selection and design of appropriate countermeasures to mitigate potential damages to bridges and other highway components at stream crossings. It is a metricated update of the version published in 1991 under Contract No. DTFH61-89-C-00003. The HEC-20 manual covers geomorphic and hydraulic factors that affect stream stability and provides a step-by-step analysis procedure for evaluating stream stability problems. Guidelines and criteria for selecting countermeasures for stream instability problems are summarized, and the design of three countermeasures (spurs, guide banks, and check dams) is presented in detail. Conceptual design considerations for many other countermeasures are summarized"--Technical report documentation page.Sponsored by Office of Technology Applications, HTA-22, Federal Highway Administration, and performed by Ayres Associates, formerly Resource Consultants & Engineers, under contract to GKY and Assoc.,

Energy losses through junction manholes / by Chang, F. M.(Fred M.)(CARDINAL)320478; United States.Federal Highway Administration.Office of Engineering & Highway Operations Research and Development.(CARDINAL)286896; GKY & Associates.(CARDINAL)284303; Turner-Fairbank Highway Research Center.(CARDINAL)286897;
Includes bibliographical references (volume 1, page 95).v. 1. Research report and design guide -- v. 2. Experimental data.Laboratory report;The objective of this report is to develop and test methodologies for computing energy losses at junction manholes. Laboratory data obtained over a 6-year period at the Federal Highway Administration's (FHWA's) Hydraulics Laboratory are analyzed within the framework of three methodologies: the energy grade line, power loss, and neural networks. Descriptions of the methods are presented, along with a statistical analysis comparing the accuracy with which each method computes observed depth in the junction manhole.Sponsored by Office of Engineering and Highway Operations R & D, Federal Highway Administration, and performed by GKY and Associates, under contract no.
