Abstract
Construction of the new cable stayed bridge on the Sava River in Belgrade - the 'Ada Bridge', required extensive foundation works at the entrance of the Ada Bay, with two environmentally unfavourable consequences -increased siltation of the Bay entrance, and dislodgement of protected bird species (the pygmy cormorant). This paper deals with actions undertaken in order to resolve these unfavourable environmental impacts. Numerical 2D flow simulations were done in order to design a reconstructed Bay entrance with reduced siltation, and to shape the existing sand bars to become, after backfilling and planting, a renewed habitat for the protected bird species.Izgradnja Mosta na Adi iziskivala je obimne radove na ulazu u Čukarički zaliv, sa dva nepovoljna uticaja po životnu sredinu - povećano zasipanje ulaza u Zaliv i proterivanje zaštićene ptičje vrste - 'malog vranca', sa njegovog staništa na špicu Ade. Ovaj članak opisuje aktivnosti na otklanjanju ovih nepoželjnih uticaja. Na osnovu proračuna kapaciteta unošenja i istaložavanja rečnog nanosa na ulazu u Zaliv, projektovano je takvo uređenje obala koje istovremeno zadovoljava određene uslove u pogledu režima strujanja vode i nanosa, ornitološke uslove obnove staništa, kao i estetske uslove regulacije obale oko pilona mosta
