A Pebble Count Procedure for Assessing Watershed Cumulative Effects (Classic Reprint)

Book excerpt: Excerpt from A Pebble Count Procedure for Assessing Watershed Cumulative Effects Our interest is in shifts in the fine gravel and smaller portion of the distribution, not the median. Therefore, through a longitudinal stream reach (most commonly a pool and riffle complex) we modified the Wolman procedure into a zig-zag pattern such that a stream reach is sampled along a continuum instead of an individual cross-section. By doing this, numerous meander bends and all associated habitat features can be sampled as an integrated unit rather than as individual cross-sections.
