This book was released on 1987 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characteristics and interactions of the riparian stand, large woody debris (LWD), and channel morphology were examined on five undisturbed, low gradient streams in southeast Alaska. One first-, two second-, one third-, and one fourth-order streams were studied. Stream morphology variables were measured systematically at fixed intervals of three to ten feet depending on stream size: 50-foot intervals were used for riparian forest measurements. The percentage of alder comprising the riparian forest increased with stream size. The first- and second-order streams had alder comprising approximately 8% of the total basal area whereas, the fourth-order stream had 25 Likewise, the percentage of LWD pieces consisting of alder increased from 129 in the two smallest first and second-order streams to 319 in the fourth-order stream. These findings, along with inspection of air photos indicate a alternating 1'one sided" alder corridor exists along the largest stream. The proportion of large woody debris pieces with rootwads in the channel increased from 2 and 6% in the two smallest first- and second-order streams to 32° in the fourth-order stream indicating the largest stream has recruited LWD from bank cutting and/or lateral channel migration. LWD oriented perpendicular (900) to general stream flow was relatively frequent for all streams. No significant (alpha=0.05) linear relationship was found (r2

This book was released on 2010 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 653: Effects of Debris on Bridge Pier Scour explores guidelines to help estimate the quantity of accumulated, flow event debris, based on the density and type of woody vegetation and river bank condition upstream and analytical procedures to quantify the effects of resulting debris-induced scour on bridge piers. The debris photographic archive, the survey questionnaire and list of respondents, and the report on the field pilot study related to development of NCHRP 653 was published as NCHRP Web-Only Document 148: Debris Photographic Archive and Supplemental Materials for NCHRP Report 653.

Available in PDF, EPUB and Kindle. Book excerpt: Biogeomorphology, a relatively new term, refers to relations between the biota and geomorphic form and process. Ecology is the study of organisms in relation to their physical and biotic environment. Thus, ecogeomorphology could have been an equally acceptable name for this publication which stresses the ecological aspects of the larger field of biology. Most of the articles relate vegetation to fluvial geomorphology, erosion, and sedimentation. However, articles showing the significance of animal ecological studies and their bearing on geomorphic form and process are also included. Geographically the papers range from arid areas in the American Southwest and Israel to the new world tropics. Most articles, however, are concerned with temperate areas of North America and Western Europe. This is among the first books to approach the role that biota and ecology play in geomorphic processes and should be on the shelf of every landscape ecologist.
