Analysis of Channel Depth, Form Ratio and Wetted Perimeter of Egbelu and Mgbuduohia Rivers of Rumuolumeni in Obio/Akpor Area of Rivers State

The study comparatively analysed channel depth, form ratio and wetted perimeter of Egbelu and Mgbuduohia Rivers of Rumuolumeni in Obio/Akpor Area of Rivers State, Nigeria. The study was anchored on system theory of minimum stream power and theory of maximum flow efficiency. Data were collected on channel depth, wetted perimeter and form ratio, using such instruments as stop watch, marine rope, global positioning system (GPS), measuring tape, floater, etc. Data were analyzed using mean, standard deviation, minimum and maximum values, range and two sample student t-test. Furthermore, channel depth was 1.52m; wetted perimeter 31.07 m; and form ratio 2.92. The mean values of the fluvial properties of Mgbuduohia River were channel depth 8.93m; wetted perimeter 59.57m; and form ratio 4.47. The results also showed that there is significant difference in channel depth, wetted perimeter and form ratio between the two rivers among the three parameters. Based on the results, the study concluded that the observed differences could be a function of differences in the input factors as well as process modification along the river channel and its basin area. The study therefore recommends periodic studies for monitoring of fluvial properties of the rivers.
