Abstract
In the western Adriatic, mass accumulation rates range between 0.04 and 6.6 g cmâ 2 yrâ 1. Peak values were recorded in the Po and Isonzo prodeltas and along a narrow belt between Pescara and the Gargano promontory. Furthermore, the latter depocentre is located immediately seaward of the offlap break (40-50 m water depth) and parallels that of the most recent sigmoid of the HST. The integration of mass accumulation rates throughout the mud wedge of the north and central Adriatic gave a value of â¼42.0 Tg yrâ 1 of sediment accumulating along the Italian coast. The balance between sediment accumulation and riverine sediment supply (â¼46.6 Tg yrâ 1) suggests an export of 4.6 Tg yrâ 1 to the south Adriatic basin and/or the Mediterranean Sea. The along-shore sediment transport is very effective and, in particular, 16.2 Tg yrâ 1 of sedimentary material (â¼35% of the riverine supply) is transferred from north to central Adriatic, through the Ancona section.
