Bentley s MicroStation Hydraulic Design/Analysis Software October 17, 2018
Update on SUDA Development from 2017 SUDA Implementation Schedule SUDA/StormCAD Tools Management Tools Scenarios vs Alternatives (Parent vs Child relationship) CivilStorm dynamic analysis Utility Clash Detection
Subsurface Utility Design and Analysis Two components: 1. Hydraulic design and analysis Storm-sewer StormCad is the hydraulic computational engine 2. Utility Clash Detection
2,762 3D Cells are complete Feature Definitions Element Templates Prototypes (Hydraulic Losses)
Develop Seed File (Template) 3D Cells Feature Definitions Rainfall Data Landuse Coefficients Hydraulic Losses Entrance/Exit, Junction losses Scenarios TxDOT Seed File ( Version 1 ) planned completion January 2019.
Geopak Drainage to be phased out in stages Bentley Phase out Schedule 1. Updates will cease in 2019 2. Bentley support will cease in 2020 3. GEOPAK will not be available (from Bentley) by 2021-2022 TxDOT Phase out Schedule 1. Geopak to be phased out after Open Roads Designer (summer 2019) 2. Exceptions made for projects started in Geopak.
New Training to start with release of SUDA TxDOT seed file in January 2019. Bentley Training TxDOT Training - Step by step, hands on using TxDOT workspace, TxDOT Seed file and example corridor
Software Progression Spreadsheets Winstorm Automated Analysis Ease of use Freeware developed by TxDOT GEOPAK Incorporated into MicroStation Automated Design and Analysis Plan and Profile sheet generation with labeling
Incorporated into MicroStation Improved Automated Design and Analysis Plan and Profile sheet generation with labeling 3D models Hydraulic Model tied to 3D Roadway Corridor model Management Tools Scenario Management Dynamic Modeling Civil Storm
Great for visualization and presentation 3D Storm-sewer Model Tied to 3D Roadway corridor Model. Changes made to Roadway vertical and horizontal alignments reflect into storm sewer model
Introduction of Scenario Management What is a scenario: A series of What If situations for a model, A collection of alternatives Allows Designer to compare and manage variations in hydraulic properties and attributes Scenarios are maintained in a single Project file In GEOPAK, to change a model Copy model Edit model (slope change, pipe change, add inlets etc) Re-calculate and review results Scenario management using inheritance with parent child relationship Biggest Improvement from previous software
Scenarios Alternatives (Building blocks of Scenarios, Set of properties) Active Topology (Isolate areas of a network) Physical (elevations, pipe sizes, roughness coeff, etc) Headloss Boundary Condition (Tail Water etc) Rainfall Runoff (Storm Frequencies) Hydrology (hydrologic method) Design (spread width, allowable velocity, cover)
Dynamic Modeling Unsteady Analysis Depth and velocity vary with time at a given location Quantify flood storage, more accurate results Incorporated into SUDA No need to Export/Import
SUDA will not be able to produce and label profiles until TxDOT implements MicroStation Open Roads Designer Open Roads Designer will not be available until TxDOT implements Windows 10 in summer 2019. Use GEOPAK on projects with larger systems Use SUDA on projects with smaller systems and cut sheets manually Use SUDA as a preliminary analysis tool
New Rainfall Data Implementation of Atlas 14 Rainfall depths Biggest rainfall depth changes are in the50 year and greater return periods. Add freeboard to HGL and Ponded Width (Spread) Linearly Interpolate between points on NOAA Atlas 14 IDF Curve Develop IDF Equations Current RTI Project to develop IDF equations
Cell Library not developed for other utilities conduit/boxes etc. Planned development after hydraulic/stormsewer component. Planned completion in December 2019
