Partial abstract: "The published evidence of reservoir-induced macroearthquakes is critically reviewed. The evidence is partitioned into three types: (a) evidence of a post-impoundment increase in seismicity, (b) correlation evidence that is composed of a plot of a reservoir variable and a seismicity variable and, in most cases, an auxiliary variable, time, and (c) evidence based on the slope of the magnitude-frequency relationship (b value evidence)."

From abstract: Tests on the Chesapeake Bay hydraulic model were conducted to specifically investigate possible changes in the hydrodynamic characteristics of velocity, salinity, and tidal elevations associated with the proposed channel enlargements.

Partial abstract: "The development of waterborne geophysical systems and techniques has provided the geotechnical community with an array of data acquisition tools that can be applied to the fluvial environment. The major purpose of the study described in this report is to evaluate the performance, application, and capability of selected waterborne acoustic profiling systems for streambank erosion studies in fluvial environments. Additional objectives of the study reported herin were to present types of available survey ssytems and related support equipment and to describe techniques for using the systems and equipment."

Abstract: "Fish, waterfowl and wading birds, and aquatic mammal populations on Lake Conway were surveyed for 1 year after the introduction of the herbivorous fish, white amur (Ctenopharyngodon idella). Low water levels reduced littoral zone area, which lead to stunted panfish and poorer condition of largemouth bass. Vegetated samples supported more diverse fish populations than beach sites. White amur and migratory waterfowl consumed the same plant foods; continued reduction of submerged plants by white amur may adversely affect overwintering waterfowl populations. Aquatic mammals were influenced by removal of vegetation due to shoreline development."
