1
J
+
Material type (IMAT).
2
ORT(J,1)
+
Turbulent exchange coefficient associated with the instantaneous
direction of flow.
3
ORT(J,2)
+
Baseline turbulent exchange coefficient. It is applied in all directions.
4
ORT(J,3)
+
Not used. Fill with any real number.
5
ORT(J,4)
+
Not used. Fill with any real number.
6
ORT(J,5)
+
Roughness-Chezy coefficient or Manning's N.
Apply Manning's if<1.0
Note: Units for turbulent exchange coefficients are lb-sec/ft2 or Pascal-sec for SI units.
