1 Bentley s MicroStation Hydraulic Design/Analysis Software October 17, 2018

2 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

3 Subsurface Utility Design and Analysis Two components: 1. Hydraulic design and analysis Storm-sewer StormCad is the hydraulic computational engine 2. Utility Clash Detection

4 2,762 3D Cells are complete Feature Definitions Element Templates Prototypes (Hydraulic Losses)

5 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.

6 Geopak Drainage to be phased out in stages Bentley Phase out Schedule 1. Updates will cease in Bentley support will cease in GEOPAK will not be available (from Bentley) by TxDOT Phase out Schedule 1. Geopak to be phased out after Open Roads Designer (summer 2019) 2. Exceptions made for projects started in Geopak.

7 New Training to start with release of SUDA TxDOT seed file in January Bentley Training TxDOT Training - Step by step, hands on using TxDOT workspace, TxDOT Seed file and example corridor

8 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

9 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

10 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

11 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

12 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)

14 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

15 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 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

16 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

17 Cell Library not developed for other utilities conduit/boxes etc. Planned development after hydraulic/stormsewer component. Planned completion in December 2019
