CHECK 2119 - SRF value is negative (adds storage) or is greater than 0.9 (little storage).

Alternate Message

Message Type

The SRF (Storage Reduction Factor) value is either negative (this will increase the storage or effective surface area of the cell) or is greater than 0.9 meaning that more than 90% of the cell's storage will be removed. A cell must have some storage and TUFLOW will automatically ensure a cell's surface area is not reduced by more than 99%. If a cell's storage is markedly reduced, this may cause instabilities. To check the SRF values view the SRF attribute in the 2d_grd_check layer. Note, the SRF feature became available as at Build 2011-09-AE.

Review the SRF values are appropriate.
