Flow in an interbay channel for water renovation in San Vicente Bay (Chile)

Abstract

San Vicente Bay, in central Chile, is a particularly polluted body of water. In this work the construction of a canal that connects it with Concepción Bay is proposed, to help decontaminate it. Using a modified version of the Vennell channel model, the water flow between the two bays is calculated, without and with a gate between them. It is shown that in the second case the combination of the tidal difference and the winds achieved in about a month the renovation of the most critical part of San Vicente Bay.
