the case of Mahin Lake Environment

Mahin Lake is situated within the trangressive mud coast and lie in the north-western flank of the Niger Delta. This lake is located within the coastal plain that stretches about 20km inland. Sediment Dynamics in this lake region is caused by erosion, which has severely affected the coastal life in this mangrove zone. Dredging activities during the creation of network of canals within this region have also been significant, and have had impact on biodiversity in this environment. The importance of visualisation techniques that use acoustic equipment to monitor the underwater and river bed cannot be overemphasized. Therefore, there is the need for governmental agencies and oil producing companies' to look at the possibility of prospecting oil and natural mineral resources in this Shrinking Lake.
