By default, TUFLOW uses the first point in the time-series curve as TUFLOW time-zero. This can be changed using the TCF command “HEC-DSS Start Date” to identify the date/time that should be used for time-zero. The date should be in the isodate format: yyyy-mm-dd hh:mm:ss, where the time portions are optional.<br>

Note: Non-time series data such as gridded data from a HEC-DSS file is not supported at this time. Contact [mailto:support@tuflow.com support@tuflow.com] to request other features that would be beneficial to your workflows.

==Is there a way to transfer a complete HEC-RAS 2D model directly to TUFLOW?==
For 2D HEC-RAS models, we recommend requesting the raw input datasets used in the HEC-RAS model, if possible, and then reconstructing a TUFLOW model from scratch. We have found that this method is easier and results in higher
