To the North of Carraixet, tracts of the Royal Irrigation Canal of Montcada serve practically as landmarks to define the contact between the piedmont plains and Pleistocene alluvial fans and a Holocene alluvial plain, all dominated by the irrigation canal and partially occupied by old marshes.

Most of the lands irrigated by irrigation canal north of Carraixet coincide with a Holocene alluvial plain, which features a gentle slope to the sea only altered by the occasional appearance of Triassic outcrops of Puig.
In this plain, the canyons lose their slight enclosure that was common in the piedmont plains and fans and vanish, integrated or dissolved, into the dense network of irrigation and drainage canals. Only in one case does it stand out as linked to some glaciofluvial deposit at Carraixet, where it borders Meliana in the south, known as the Barranquet, or some recent deposit in the shape of a fan, as presented by the ravine of the Calderona above the marsh of Puçol.
It is also difficult to establish with precision the limit between these deposits and the marshes, since the progressive reduction of wetlands by anthropic action has blurred the contact between both environments.
