Determination of downstream hydraulics geometry parameters

The hydraulic geometry term represents the relations between the dynamic characteristics of a river stream and its discharge. The river character istics quantitatively obtained by describing these parameters as power functions
of discharge employing one coefficient and exponent. The aim of the study is determining the downstream hydraulic geometry parameters and to obtain a relation between flow discharge and sediment discharge with hydraulic geometry
parameters of the charmel. Depth, velocity, width, siuface roughness and suspended sediment eoncentration data are collected at three selected stations along the channel. The downstream hydraulic geometry parameters for flow discharge relations b, f, m, p, a, c, k and N discovered as 0.0417, 0.8889, 0.0789, 0.4580, 1.9842, 1.9710, 0.3693 and 1.8056 respectively. For sediment discharge relations, the hydraulic geometry parameters b, f, m, p, a, c, k and N
shown as -0.0454, 0.9054, 0.3090, 0.1739, 1.1712, 2.1230, 0.3348 and 0.9325 respectively. The values of exponent and coefficient, (b, f, m, p, a, c, k and N) varies within some limits imposed more by ways the adjustment of stream power is dispersed across variables. This is because the scales parameters are varying and depends on the hydraulics parameters of chaimel. In addition, according to the results, the sediment and flow discharge relations at Station 1 were determined being more relevant than those at a different station when it comes to the correlation coefficient. Generally, the findings from this study are intended to be beneficial for manager and planner of water resources initiatives in the basin.
