	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-quality data input for TUFLOW, as opposed to using data that has been downscaled to the HEC-RAS grid resolution. Additionally, RAS and TUFLOW use different grid mesh formations, which makes a direct automated conversion impractical.

	The ~~2022~~ TUFLOW Release introduced support for time-series data from HEC-DSS files within a TUFLOW boundary condition database.		The 2023 TUFLOW Release introduced support for time-series data from HEC-DSS files within a TUFLOW boundary condition database.

	HEC-DSS is a database system for time series, curve, gridded data and more, developed by the U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC). See their website at https://www.hec.usace.army.mil/software/hec-dss/ for more information. The format is used for HEC developed software for data input and output. Rather than convert HEC-DSS time-series curves for use in TUFLOW, DSS data used by a HEC-RAS model can now also be used directly in TUFLOW.<br>		HEC-DSS is a database system for time series, curve, gridded data and more, developed by the U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC).
