Paper Title:
Deposited Sediment Dredging to Reduce Internal Pollutant Loading for a Waterfront Shallow Lake in Zhenjiang of China
  Abstract

Due to the geographical location, sediment deposition resulted in a heavy internal pollutant loading and destroied the ecological system in Neijiang, a typical waterfront shallow lake. Based on the field investigation and laboratory experiment the characteristics of deposited sediments including deposition thickness, pollutant contents and pollutant release intensity were analyzed and then the sediment dredging schemes for Neijiang were proposed. Finally the impacts of sediment dredging on internal pollutant loading were quantificationally evaluated. It was found that:(1) the deposition thickness, pollutant contents and release intensity of sediments in Neijiang were all distibuted asymmetrically; (2) sediment dredging significantly decreased the basal elevation of Neijiang and cut down the internal pollutant sources by removing the surface contaminated sediments; (3) After dredging the internal pollutant loading under different hydrological conditions in Neijiang was evidently reduced.
