Thank you for the attention.
In my study, the stretch of the river is very plain and the high tide influences until 3500m the sum, and the minimum tide until 550m. In the case to use the dynamic flow, together with the influence of the hidrograma of rains accused error in the data, finds that it was in function of the minimum tide not to influence in all stretch. From there, I coincided the quota of deep of the river as if it was the quota in the too much point and the program functioned, but, I was not with certainty that what I made was correct. Debtor one more time, Clarice
