Abstract:
The Ilha Solteira dam reservoir, which has an extension of 100 km, is located in the northwest
of São Paulo state, Brazil. Due to its huge dimension, wind generated waves can cause
problems to the navigation security, to the stability of the river banks, to the infrastructures
around the reservoir or even to public safety. In 2010/2011, a field data campaign was
undertaken in order to measure the wave height and wind velocity. The bottom profile and
wind velocity were used on the SWAN (Simulating Waves Nearshore) to predict the wave
height. From the obtained results it can be said that the prediction from the numerical model
presents similarities with the experimental ones.
