Generate drainage reports quickly by exposing all of the available inputs, outputs, simulation results, design results, calculated values, etc., all in one table based on connectivity.

Identify and address simulation errors without the need for extensive guesswork and manual checking. The tool highlights where the problem is and which storm is associated with it. A "go to" button enables you to jump directly to the problematic element, saving time and effort in troubleshooting.

Plot the Hydraulic Grade Line (HGL) and Energy Grade Line (EGL) within the long section of the drainage network.

Enhance the design process with Clash Detection Analysis. Identify and visualize "clashes" or intersections between different components within your design, such as pipes, channels, or other structures. 

Generate responsive flood maps utilizing the new Machine Learning Deluge tool, powered by Autodesk AI. Identify patterns between the ground model and the resulting flood map, then see hotspots to establish the best locations for storage structures and stormwater controls.

Users now have access to a comprehensive selection of 57 culvert types, including circular, box culverts, ellipses, and arches, with various shapes and entrances. This new feature enables more accurate and detailed modeling of culvert behavior, enhancing the overall drainage design process.

Land use and soil type polygons allow you to incorporate detailed polygon attributes to refine hydrological calculations for each sub-catchment, providing a more accurate and spatially informed approach to drainage design.

Civil 3D round-tripping enables seamless connections between your civil design and hydraulic analysis process. Export catchments from Civil 3D with the toolbar and make responsive changes in InfoDrainage, including direct results migration between platforms.

Run a variety of rainfall and runoff calculations for your region in the cloud. Both 1D and 2D analysis involving rainfall and runoff calculations can now be processed in the cloud, enhancing design workflows through a robust, multi-regional data center architecture.

HEC-22 inlet calculations now account for the grate type and the throat angle, both critical factors affecting water inflow rates into the inlet. By incorporating these parameters, we aim to provide a more realistic representation of how drainage inlets perform under varying conditions.

InfoDrainage 2026 includes backwards compatibility, allowing you to work with both InfoDrainage 2025 and Civil 3D 2025 — simplifying the process of sharing models and eliminating compatibility issues.

Extended shape added to the Desbordes French Rainfall with additional durations up to two weeks.

You can specify materials for pipes and structures/manholes to control the cost and durability directly within your project.
