RESTORATION OF THE KISSIMMEE RIVER, FLORIDA: WATER QUALITY IMPACTS FROM CANAL BACKFILING

摘要

the planned restoration of the Kissimmee River ecocystem will backfill approximately 35 km of flood control canal (C-38) that cuts through the meandering river channel, re-establish natural flow patterns, and restore the river/floodplain ecosystem. Water quality monitoring, including nutrients, total suspended solids (TSS), turbidity, dissolved oxygen (DO), and meercury, was conducted during a pilot `test fill' project to determine if soil disturbance during canal backfilling would negatively impact trhese water quality constituents. Surface water nutrient concentrations varied little between sites. Generally, highest concentrations occurred prior to construction, with lowest concentrations occurring during and after construciton.
