2. Hydraulics Geometry Analysis of UPNM Channel

Depth, width, velocity and suspended load are essential hydraulic features that are determined mainly in the form of the river cross-section. The objective of this study is to measure the hydraulic geometry parameters at station and investigate the relationship between hydraulic geometry parameters with suspended sediment concentration of the Universiti Pertahanan Nasional Malaysia (UPNM) channel. In the analyses on the channel, three stations were selected. All of these stations have sediment discharge, flow discharge and cross-sections measured data. Result shows that at relationship of discharge and hydraulic geometry parameters b, f, m, a, c and k were obtained to be −0.0440, 0.1386, 0.3305, 1.4948, 0.3670 and 0.4868 respectively. While the average hydraulic geometry sediment rating at every station found to be 0.2728, 0.3765, 0.3745, 3.9596, 1.9478 and 1.4601 respectively. Moreover, suspended sediment discharge and flow discharge shows a good average correlation coefficient and exponent of 0.0112 and 2.7031 exponent, respectively. Overall, the results of this research should be useful for watering the basin, management and resource planning projects.
