Model Name: TC-01_Chapra_AntDiff_Test_Case

Objective: Use EFDC_Explorer (EE) and EFDC+ to replicate the test case for studying diffusivity effects on parameters outlined by Stephen C. Chapra in his book “Surface Water-Quality Modeling” (2008) for Distributed Series (Time Variable).  This simulates a “breakthrough” curve and the change in concentration at a point 2,000 m downstream for conservative and non-conservative releases. This model is a 1D channel of 100 cells with AHO set to 5 m²/s.  The measured data provided in the data folder can be used to compare the empirically calculated dye concentration with output from the model. The model is running fine with reasonable agreement to measured dye concentration.

Model Grid: 100 horizontal grid cells and one vertical layer.
