Model Name: TC-06_Yen&Lee_SEDZLJ_7Across_VR _Test_Case

Objective: Use EFDC_Explorer (EE) and EFDC+ to simulate the test case described in the journal paper “Bed Topography and Sediment Sorting in Channel Bend with Unsteady Flow.” Based on the Yen & Lee (1995) paper of bed sorting, DSI have modified the original test case to not have any exit, i.e. the system is closed with respect to sediments and toxics.  This enables simple mass balance accounting to ensure proper behavior of the model. This has allowed correction to the original SNL code, with improvements in EFDC+ mass balance of a factor of 10 to 0.055% (EE8.3).

Model Grid: 301 horizontal grid cells, 4 vertical water column layers, and 8 sediment layers.
