Investigation of Drainage Inverts levels for optimal Functionality in a Section of Onne Multipurpose Terminal: Rivers State, Nigeria
Abstract
The section of Onne Multipurpose Terminal under study is usually flooded especially when it rains heavily. The inability of existing drainage system to discharging rain water to the river through the existing carnal has also resulted to the occurance of stagnant water in the drainage under study. The study is therefore aimed to investigate the status of the drainage invert levels with the objective of determining the change in invert level at chainage of Five meter 5m interval, determine the tidal levels at the existing canal and proposed a water discharge point. The study methodology was based on the classical (conventional) surveying techniques which involves the determination of the distances, directions and elevation between series of points. The Lieca flexline TS06plus Total Station Instrument with 3mm accuracy and Kolida K9TX (DGPS) GNSS Reciever with 2mm accuracy and were deployed to acquire spatial data of the drainage system under study, this data includes drainage position, elevation and invert levels. The results revealed a highest and lowest invert levels of 2.713m and 2.125 respectively with a change in invert level of between 0.002m to 0.593m. this findings indicates an inconsistence differences in invert level at chainage of 5m along the drainage profile, this means that the drainage gradient has been heavely impacted resulting to its inability to discharge water to the to the river through the existing canal. Redesigning and reconstruction of the drainage using acquired spatial data from this study is neccesary to prevent total collapse of the drain and continous flash flood and stagnant water in the environment.
