Infratech Civil

Product:  Autodesk SSA  |   Subject: Storm and Sanitary Analysis

In this exercise, we will learn about stormwater hydrology and hydraulic.

In this course, entitled Advanced Stormwater Design, we will learn to design stormwater facilities, by integrating two design software: Autodesk Storm and Sanitary Analysis and Civil 3D.  

Using these two tools, we will analyze, design, and illustrate simple and complex H&H (Hydrology and Hydraulic) models.  Hydrology is the scientific analysis of water with a focus on the water cycle through natural flows and transformations, such as precipitation, collection, evaporation, condensation, and transportation.

Hydraulics, on the other side, represents the study of the mechanical

properties of liquids. In the current case, the term will be restricted to the study of the flow of water in urban and rural infrastructures such as closed conduits, ditches, channels, ponds, etc.

The goal of this course is to be able to complete the design of tasks such as:

• Setting up an H&H (Hydraulics and Hydrology) model, including structures, conveyance systems, storage nodes, control structures, and the likes.
• Analyzing a model; and
• Reporting the results.

To complete the tasks above, we will use the design tools available in the two design packages:  Autodesk Civil 3D and Storm and Sanitary Analysis (SSA). These two complementary software packages are part of the same installation of Civil 3D. It is unbeknownst to many users, but SSA is automatically installed with Civil 3D, and it is readily available out of the box. We will see later where to access the installed SSA package.

Hydrology and Hydraulic design workflow in Civil 3D and SSA

Autodesk® Storm and Sanitary Analysis (SSA) is the Civil 3D add-on package that allows us to perform advanced and comprehensive modeling of stormwater and sanitary sewer systems.

In this course, entitled “Advanced Civil 3D: Stormwater Design”, we will learn how to use SSA to analyze and design both stormwater and sanitary sewer networks.

We will follow a typical stormwater design process, which generally includes the following steps.

1. Laying out the preliminary drainage network in Civil 3D.
2. Exporting the preliminary Civil 3D system to SSA.
3. Performing the detailed hydrologic and hydraulic design of the system in SSA. This process is meant to provide a final design that will meet the local regulatory codes and basic H&H requirements.
4. Importing the final design into Civil 3D and automatically update final construction drawings.
