• Abstract:
  Cataloging and synthesizing existing methods for the design of roadway-stream crossings for fish passage began in ; January 2005 with an extensive literature review covering the topics of culvert design and assessment to facilitate ; fish passage. A survey was posted online to gather input from design professionals across the country, and a ; Culvert Summit Meeting was held in Denver Colorado from February 15-16, 2006, to allow presentation and ; discussion of state-of-practice design and assessment techniques. Following the Summit meeting, a Technical ; Advisory Committee was developed with individuals specifically knowledgeable in the topics of interest. Members ; were crucial in shaping and reviewing the direction of these guidelines. ; This document places current culvert design techniques into four categories based on design premise and ; objectives. These categories include: No Impedance techniques, which span the entire stream channel and ; floodplain; Geomorphic Simulation techniques, which create fish passage by matching natural channel conditions ; within the culvert crossing; Hydraulic Simulation techniques, which attempt to closely resemble hydraulic diversity ; found in the natural channels through the use of natural and oversized substrate; and Hydraulic Design techniques, ; which may utilize roughness elements such as baffles and weirs to meet species specific fish passage criteria during ; periods of fish movement. ; Preliminary chapters covering the topics of fish biology and capabilities, culverts as barriers, fish passage hydrology, ; and design considerations aid in the selection of appropriate design techniques based on hydraulic, biologic, and ; geomorphic considerations. A further section presents examples of design techniques fitting the defined design ; categories. Design examples and case histories for a selection of design techniques are presented next, and are ; followed by a discussion on construction, maintenance, monitoring, and future research needs.
