2 Comprimento talvegue (km)= L= 45<<strong>br</strong> />
3 Distancia do centroi<strong>de</strong> a seção (km)=Lo= 25<<strong>br</strong> />
4 Ct adotado= 1,257<<strong>br</strong> />
5 Cp adotado= 0,576<<strong>br</strong> />
Tempo do centroi<strong>de</strong> até a seção (h)=tL= 7,76<<strong>br</strong> />
Duração da chuva padrão (h) td= 1,41<<strong>br</strong> />
