Locating Manning-based Satellite Gauging Reach for River Discharge Estimation from Remotely Sensed Imagery

River discharge is critical for understanding river hydrological condition and water resource management. With the advance of earth observation technologies, estimating river discharge through remote sensing using Manning's Equation has become more and more popular for filling the gaps in gauging observations. However, finding a Manning-based Satellite Gauging Reach (MSGR) that can successfully transfer satellite signals into river discharge based on the Equation is not easy and lacks proper guidance. Theredore, we provide a practical approach for locating MSGR.<br> The manuscript is currently under review by Water Resources Research.<br> This repositry is the data for reproducing the figures in our manuscript. This repositry consists of four part. They are the corresponding data and results at MSGR, CR_FSE, CR_SCT locations, and elevation values along river centerline for calculating riverbed slope.
