Estimate of hydraulic parameters of overland flow

Estimate of hydraulic parameters of overland flow

Acta Agriculturae Universitatis Jiangxiensis 28(3): 477-480

Relationships between flow velocity, flow depth, flow discharge, and slope gradient were simulated in a hydraulic flume. Results showed that the flow mean velocity could be well simulated by a power function of flow discharge and slope gradient. The determination coefficient R2 was 0.92. Flow depth increased as a linear function of slope gradient, and increased as a power function of flow discharge. The determination coefficient R2 was 0.98.
