Aquaterra - BIM ready solution for Channel & River Engineering Design

Aquaterra is a professional 3D CAD software for channel and river engineering design. It integrates MIKE FLOOD or HEC-RAS hydraulic calculations with flood protection design, torrent and landslide control, and irrigation systems design.

Based on layout, profile, and cross-sections, it creates 3D solid channel and river bed models, supports QTO data export, and offers plan production tools. Carefully designed UI and workflows are consistent with the engineering practices. This makes Aquaterra surprisingly fast-to-learn and easy-to-use.



Aquaterra licensing and purchase options

Aquaterra can be purchased as perpetual license, with or without maintenance or it can be rented for various time periods. Single and network licenses are available. CGS Labs also offers a very attractive CGS Labs financing option (PAY1/USE5) which allows instant use of sufficient number of licenses, payment in monthly rates at a longer time-period, thus significantly increasing the value of your investment. Contact us for detailed information!



Digital terrain modeling

The Surface creation tool is included in CGS Labs software to produce detailed Digital Terrain Model (DTM) based on various surveys or other input data: total station data files, points, break lines, blocks, etc. This offers the possibility to use Aquaterra on plain AutoCAD or BricsCAD.

River alignment design tools

Aquaterra provides a wide range of advanced alignment, profile geometry design, and editing tools. They include P(V)I design, floating and fixed elements design, alignment design created from the existing polyline, or ultimately creating a best-fit alignment based on existing channel or river bed survey data. A number of alignment labels, reports and data export options give you the flexibility to cover a wide range of user requirements.

Water level representation and smart lines definition

Water level lines represent data obtained from hydraulic calculation software (MIKE FLOOD or HEC-RAS). They are displayed relative to the specific alignment in the drawing. To present side objects like channels, dykes, property limits, etc., you can define smart lines in the layout and project them to profile and/or cross section views. The Smart lines functionality is connected with the point’s projection, which offers similar projection options, but dedicated to point objects along any alignment.

Cross sections design and editing capabilities

Enter 1D, 2D water levels or combined calculations and design new or edit existing channel and river bed cross sections geometry. Add dykes and other objects using the large set of tools available. Recalculate water levels and check geometry changes impact for accurate project evaluation.

Quantity take-off (QTO)

Aquaterra calculates material quantity take-off and features a QTO data export tool with custom defined Pay Item (Bill of materials) options. It gives users the possibility to link material defined in the drawing with a material database in cost estimate software, thus supporting digital data transfer and fast cost recalculation when project changes arise.

River groins

Groins are a rigid hydraulic structures built from a bank in rivers that interrupt water flow and limit the movement of sediment. Aquaterra supports design of groins along selected banks as 2D elements with varying gradient values.

3D Surface and 3D Solid Model

Channel and river bed 3D model can be created as 3D surface or 3D solid model. 3D surface model can be generated automatically from 3D channel or river bed cross sections definition and terrain model, or it can be built with the grading function. 3D solid model is created on the basis of cross-section areas, with materials and volumes defined as extended data. All solid models, including extended data, can be imported into Autodesk Infraworks, Navisworks and can be used in various BIM workflows.


MIKE FLOOD by DHI is an advanced professional flood modeling solution that enables simulation of any flood problem. It can involve rivers, floodplains, flooding in streets, drainage networks, coastal areas, dams, levee and dike breaches, or any combination of these. 

Aquaterra’s integrated MIKE FLOOD interface transfers graphical data into MIKE FLOOD where water flow calculations are made. These results are transferred back into Aquaterra where water levels can be displayed in profile and cross section.

MIKE FLOOD 2D results (floodplain lines) export to Aquaterra is also supported for drawing production within the CAD environment.


HEC-RAS is an established software for one-dimensional steady flow and two-dimensional unsteady flow hydraulic calculations. 

Aquaterra’s integrated HEC-RAS interface enables the transfer of channel or river geometry from a CAD environment into HEC-RAS where water flow calculations are made. Calculation results can be transferred back into Aquaterra where calculated water levels are displayed in profile and cross sections. Taking into account the results, engineers can now modify existing channel or river topography, using Aquaterra’s advanced cross-section design and editing tools. 

Through Aquaterra’s interface, geometry can also be imported directly from HEC-RAS, edited in Aquaterra and sent back to HEC-RAS for further analysis.



Dynamic Data Model

Aquaterra stores all design data inside a .dwg data file, making for quick geometry updates and data exchanges within CGS Labs and Autodesk software solutions. LandXML and AutoCAD Civil 3D data exchange interfaces are available. Dynamic updates to all geometry changes or design parameters are supported within single or multiple drawings with separated layout/profile and cross sections data.

Supporting Large Projects

Aquaterra easily handles large projects with very long alignments and thousands of cross-sections within seconds. Projects are neither limited in size nor is the performance critically affected while working on large scale projects, including extra long and multiple alignments, profiles, and cross section views. Cross sections can provide a high level of details with on-demand synchronization options, great processing speed, and consistent data.

Intuitive user interfaces and workflows

User oriented ribbon layout and comprehensive dialogues enable fast learning for the first time users while toolbox and command line options provide faster design options for experienced users. Aquaterra time-saving UI design and simple to follow workflows help users to use their creativity without compromising engineering efficiency. Automated functions make designs time saving.


Aquaterra is available in several languages. Customers are entitled to use any country specific version of the software in case of designing projects for the foreign countries. Currently supported language versions are:

  • Croatian,
  • English (International),
  • German,
  • Serbian,
  • Slovenian.


    Extend Plateia’s functionality with point cloud data processing software - 3Dsurvey

    3Dsurvey is a standalone software solution for point cloud data processing. Use any UAV with Lidar, a digital camera, DSLR, or a GoPro to capture images and process them in 3Dsurvey. Create orthophoto data or digital terrain models, calculate volumes, profiles, and even more. Export digital terrain models to Plateia to create road projects based on detailed surface model, calculate material volumes, and export 3D road surface models from Plateia back to 3Dsurvey to create stunning aerial or drive-through visualizations. 

    3Dsurvey is available as Plateia add-on (bundled) software solution.


    Supported CAD platforms

    CGS Labs applications run on top of 2020-2013 versions of AutoCAD Civil 3D, AutoCAD or AutoCAD Map 3D as well as BricsCAD Pro and Platinum V19-V15. Only 64-bit versions are supported!
