River works for the Simao River shall therefore adopt a new approach to river training that reflects the interna- tional state of the art.In the past,differentiated,natural river alignments could not be verified hydraulically.Therefore often technical designs with simple cross sections and more fortification than required were chosen for security reasons.This is no longer necessary,as new tools now allow calculation of varying slopes and alignments in river works and more attractive,close-to-nature designs can be implemented.
