Resumen

Laboratory experiments were conducted to measure local scour around cylindrical piers in different arrangements. Also experimental data was compiled for each arrangement to develop semi-empirical equations by means of statistical analyses. The methodology of Salim & Jones (1996) was tested with the experimental data and a new equation to predict scouring in pile groups is proposed. Finally the goodness of piers with slot is verified as a mechanism to minimise the scouring phenomenon.
