The 2022 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 files organise data into paths with six parts (Part A – Part F) that resemble how files are organised on disk. The image below shows an example DSS file with a single path, with the curve plotted below.<br>
