Abstract
Split (Southern Croatia) submarine outfall, whose construction will begin in
September 2001, represents a key disposal facility of centralized Split/Solin
Northern Basin sewerage system, which drains the area with some 60.000
inhabitants. Construction of this outfall will enable all preliminarly treated
communal wastewater to be discharged into the Brae channel via 2,750 m long
HDPE pipeline, ending up at a depth of 36 m. In order to check the consequences
of various discharge scenarios, the outfall operation impact has been preliminarly
tested by means of 3-D mathematical and hydraulic model. Performed tests
confirm that the submerged morphological barrier, located westward to the
planned outfall diffuser section location, con
