We are pleased to announce the new RiverFlow2D and OilFlow2D version 8.04. Some of the exciting new features include:
NEW FEATURES in v8.10
New capabilities for all modules
• Support for QGIS v3.22.10: This new version supports the QGIS v3.22.10 long-term release, which includes new features and performance improvements.
• Numerous optimization and GPU speedup improvements.
Basic Hydrodynamics Model
• Piping and erosive dam breach features (CPU and GPU). Allows simulating dam breaches, including the evolution of the breach considering, prescribed breach, piping, and overtopping erosion.
Mud, Debris Flow, and Tailings Module (MT)
• Improved hydraulic components: Weirs, Dam breach, Internal Rating Tables, and Sources.
• New basal resistance formula for frictional shear-thinning and shear-thickening materials (Herschel-Bulkley).
• Settling velocity factor specific for each sediment class.
• New table-specified mode for concentration-depending viscosity and yield stress in MT and MT-GPU modules.
• Piping and erosive dam breach features (CPU and GPU). Allows simulating dam breaches, including the evolution of the breach considering, prescribed breach, piping, and overtopping erosion for hyperconcentrated flows.
Sediment Transport Module (ST)
• Settling velocity factor specific for each sediment class.
• Tidal inlet condition that allows imposing water elevation (tides) and suspended sediment concentrations.
PL: Pollutant Transport Module
• Tidal inlet condition that allows imposing water elevation (tides) and pollutant concentrations.
OilFlow2D on Land Model
• Weirs are now operative with the overland spills with heat transfer in CPU and GPU
OilFlow2D on Water Model
• New Oil Particle State Map. Allows mapping oil on the shore, on the bottom, and within the mesh at any time.
• Optimized particle-tracking searching algorithm allows 100X improvement in model performance.
• Output .png graphic files with particle trajectory during simulations.
• New oil volume per unit area maps and animations.
• New maximum oil volume per unit area map.
QGIS RiverFlow2D and OilFlow2D Plugins
• Weirs component: now works with 3D polylines allowing editing of both the weir polyline geometry and crest elevations.
• Breaklines used in the MeshBreakLine layer and in the Bridges, Gates, Weirs, or Dam Breach components can now join or have intersections at polyline vertices.
• Improved Flood arrival time map. Allows setting the threshold depth to consider flooding conditions.
HEEF: Hydraulic-Economic Evaluation of Flood Costs Component
• Updated Hydraulic-Economic Evaluation of Flood costs (HEEF). Allows creating damage cost maps based on polygon vulnerability functions and RiverFlow2D-OilFlow2D model results.
• Includes a default vulnerability database and database with flood damage costs for various types of structures.
• This component was developed by Hydronia with the support of the Interamerican Development Bank IADB.
NEW CAPABILITIES COMING UP IN 2022 AND EARLY 2023
1. Multiple scenario management in QGIS.
2. ST/MT active layer: Spatially and temporal variation of bed sediment fractions.
3. Simplified 1D/2D.
4. Culvert inflow and outflow polygons.
5. Improvement of the Bridges component.
6. Operational rules for components.
7. SWMM Inflow rating tables and discharge formulas for surface-storm drain exchange points.
8. OilFlow2D On-Land Model: Pipeline component to determine spill discharges along pipelines using unsteady dynamic pipe flow analysis.
9. OilFlow2D On-Water Model: Containment Booms. Will allow entering polylines representing containment booms and considering how these devices capture oil being spilled on water.
