For over forty years, the NAVFAC DM (Design Manual) 7 Series has been the classic reference on geotechnical engineering. This volume (Foundations and Earth Structures, DM 7.02) is the second volume.... More > It covers a wide variety of topics, including excavations; compaction, earthwork and hydraulic fills; analysis of walls and retaining structures; shallow foundations, and deep foundations. Complete with glossary. Also with a new foreword and a cover photo by J. Ledlie Klosky.< Less

Streambeds provide for the necessary habitats and spawning cycles of a healthy fish population. Oregon law requires underwater hydraulic structures to provide proper fish passage. Increasingly... More > stringent regulations apply to fish passageways, and designers must consider a range of flows to accommodate fish movement and avoid structural failure. Fish passages, culverts or bridges, are built where roads cross streambeds. “Roughened channels” technique re-creates streambeds with the hydraulics necessary for adequate fish passage. This report examines long-term success factors for implementation of fish passageways, especially in the construction phase, and examines whether failures are due to inadequate range and mix of material gradation; unexpected water velocity; or inadequate mixing or compaction of materials during construction. Other factors may include the relationship of downstream slope to structure slope, well-graded fine soil materials in channel fill, and frequent site visits.< Less
