Innovative Environmental-Driven Decisions on River Bed Clearing and Dredging.

Abstract

There were considered projects on clearing from pollutions and dredging bottom and river beds of surface water bн company “Van Oord”. Projects concurrently with clearing are solved environmentally important task treatment with withdrawn contaminated subsoil for purpose of create minimal load on environment, organization of problem-oriented reservoirs; new technological solutions of company on separation of contaminated fractions from purified subsoil with indication of area of use for this part of subsoil in economic operations. There was showed role of dredging works in improvement of influence on environment by means of changing conditions of water exchange and run-off of surface waters. There were denominated fields of applications of hydrodynamic models and programmes for receiving and processing of telemetric’s initial values on accurate assessment of environmental plume in the performance of operations on clearing and dredging of surface waters. Given examples of special equipment’s use and technological solutions for certain completed projects on dredging and riverbank treatment and bottoms of surface waters.
