Abstract :
The purpose of environmental impact assessment is to identify, analyse and evaluate project activities. Environmental Impact Assessment ensures the environmental concept of sustainable development by providing the necessary environmental information to determine the environmental friendliness of a proposed project. Mechanical harvesting of aquatic plants along with biological and reed harvesting in the whole area of West Wetland and opening the entrance of Chafrud River were the main activities that could be implemented in this project. Mechanical harvesting operations are performed with a Harvester machine and reed harvesting is done with a motor saw or manually. The most important activities of the project are mechanical harvesting (reed harvesting and immersion of aquatic plants floating with the Harvester machine), restoration and cleaning of waterways (Chafrud River), dewatering and rehabilitation of West Wetland, biological control and operation of wooden bridge and bird watching station. Environmental parameters, consequences and nature of the effect, impact time, magnitude of the effect and the scope of the effect were investigated and the positive and negative effects of the design were determined.
