Phenomenological model of the intensity, duration and frequency of precipitation patterns for the Portoviejo river basin, Ecuador

RUDN Journal of Engineering Research, 2022
Phenomenological models represent the behavior of random phenomena in reality, the model and the function it should perform. Similarly, tuning parameters allow us to assess the fit of observed data to a variable in a particular mathematical model and to ...
