Sedimentological and Geochemical Characterization of Surficial Sediment of a Meander Section of Mbaa River at Nneise–Ugiri Community in Imo State of Nigeria

Raphael Oaikhena Oyanyan, Martin Chijioke Nwachukwu, Modestus Chijioke Ohaegbulem & Nonyelum Stella Iloanya · Journal of Geography, Environment and Earth Science International · 2019

Sediment deposition has increased at a meander section of Mbaa river resulting in a drastic reduction of water storage. It has necessitated calls for sand-mining or periodic dredging which could have far-reaching impacts on the aquatic ecosystem, depending on the texture and chem...
