Abstract :
    Dredging is a new technology in engineering geology that is used to determine the mechanical properties of soil and rock. However, the use of dredging in the environment faces many challenges. In this article, dredging challenges in environmental geology have been investigated. These challenges include: interactions of the soil crust with the surface, electrode feeding, water infiltration into the soil, electrode feeding in clay soils and soil slippage, the effect of lateral pressure on dredging results, and the lack of accuracy in dredging results due to lack of control. Full on laboratory conditions. Having the precision and accuracy of Laplace results and integration with other data is one of the advantages of dredging. However, for the effective use of dredging in environmental geology, its technical and operational challenges must be addressed. Some pollutions such as heavy metals (mercury, copper, lead...) have inorganic origin and some other organic substances such as hydrocarbons do not. Contaminated dredged material is discussed in more detail. The origin of the pollutants, the method of dredging the pollutants as well as the strategies to deal with their environmental consequences are explained. The importance of paying attention to the geotechnical characteristics of the dredged materials in the proper management of the disposal of the polluted dredged materials is emphasized.
