1. Introduction

This tutorial provides guidance on how to set up an EFDC SEDZLJ sediment model of the Yen & Lee experiment which measured bed topography and sediment sorting in a channel bend subject to unsteady flow conditions. This model is available for download from the EEMS website and some input files from are needed from this to follow this guidance. 

...

This model example is based on the Yen & Lee experiment and is constructed in EE10 using the state-of the-art sediment transport sub-model SEDZLJ developed by Sandia National Laboratories and now which has been incorporated to EEMS
