Manning’s method for discharge measurement
![Page 7: A Prototype for the Continuous and Cost-Effective Measurement of River Discharge](https://reader035.vdocuments.mx/reader035/viewer/2022062504/5a4d1b6b7f8b9ab0599b330b/html5/thumbnails/7.jpg)
Manning’s formula
Where:Q – dischargen – Manning’s coefficient of rugosityA – area of the cross section of the riverR – hydraulic radiusS – free surface slope
