Abstract:

Several geometric characteristics of water-basin regimes, including basin size and shape, area underwater at specific water depth, and cross-sectional area, are commonly associated with benthic, plankton, and fish community population structures, although little quantitative data are available to support the association. This two-volume report describes a general procedure that was developed to calculate values of selected parameters used to define the above-mentioned geometric characteristics of any water-basin regime. The procedure was successfully applied to yield quantitative information for those parameters for 18 side channels of the Middle Mississippi River. Which of the parameters selected as quantitative descriptors of the characteristics are best indicators of animal community population structures is expected to be determined as a result of other projects currently under way at the U. S. Army Engineer Waterways Experiment Station. Volume I contains a description of the procedure and the results of implementing it Volume II contains a set of computer-plotted contour maps for the 18 side channels. Author
