“…The data generated by this work brings a valuable contribution to a series of studies conducted on the São Francisco River to estimate discharge from remote sensing data. It complements a number of other studies that have used remote sensing image data to estimate flood return period (Maillard et al, 2018) and altimetry data to estimate water level (Maillard et al, 2015) and slope (Martins et al, 2019).…”

Abstract. A method is presented to produce river cross section profiles from a time series of Sentinel-1 images paired with water level data. Four programs are presented that generate river width data and cross section profiles from SAR or optical images. The programs generate a river bank and island width database with minimum manual intervention. Water level data from in situ stations are interpolated to match the width data and create elevation points from which the cross section profiles are produced. The method is fully described and tested on the São Francisco River in Brazil. The width data are plotted against discharge data to compare their progression. Over 1700 cross sections were produced and classified by their shape. Potential and limitations are presented.
