Extraction of shoreline using Matlab

Posted on 2020-08-03 | In Tools

Abstract

The Matlab code was developed for extracting the shoreline in our JGR-ES paper (Gao et al., 2019) and GRL paper (Gao et al., 2018), using the elevation results of Delft3D simulations. The procedures basically follow those proposed in Shaw et al. (2008).
