Verhagen, H.J. (author), Starink, A.C. (author)The calculations of bottom changes presented in our report "Terminal do Seixal Hydro-morphological study", February 1982 were based on a calibrated sediment transport formula. This formula was calibrated with the results of measurements made by Hydronamic in September 1981. These measurements were executed during one of the driest summers...report 1982
