Introduction Dredging is a fundamental activity to ensure port navigability, sediment management, and the hydraulic safety of rivers, canals, and artificial basins. However, it also involves significant environmental impacts that require careful management and appropriate technologies. This article analyzes the main environmental issues related to dredging and illustrates the sustainable ...
Pelagic zone: Open water where phytoplankton dominate primary production and where harmful algal blooms concentrate during stratification. Benthic zone: Sediments where phosphorus accumulates and releases; the condition of this zone largely determines how long a lake continues producing blooms after external nutrient inputs are reduced. ...
In-water works such as dredging, piling and trenching stir up sediment that can: Smother benthic habitats Reduce water clarity, affecting photosynthesis in seagrass and other plants Transport attached contaminants further afield A properly designed and installed silt curtain creates a controlled zone where turbidity is contained and allowed to settle, significantly reducing ...
