Investigação sobre a representação de curvas cota-volume de pequenos açudes

Abstract

The objective of this work is to show the investigation carried out on the methods used to obtain relations of the dimension-volume curves (CV) of small dams. Four calculation methods were used i) Habili, based on the form factor, ii) SUDENE method, based on the geometric parameters K and α, iii) the second degree polynomials iv) and the third degree polynomials. Applications of the methods were made in 10 dams located in the state of Paraíba. Comparisons were made between the performance of the methods through the errors produced in each. In general, the method that produced the most adequate results was the third-degree polynomial. However, SUDENE’s and Habili’s methods demonstrated advantageous characteristics.
