Welcome to Hydrata

Hydrata is an online surface water modelling platform. You build, run, collaborate on, and publish flood models from your web browser, with simulations powered by the open-source ANUGA hydrodynamic engine on cloud compute.

There is no software to install and no dedicated hardware to maintain. Once a project owner sets an access policy, anyone permitted can view, update, and run the model, so your work stays transparent, reproducible, and up to date.

What do you want to do?

• Start modelling

  ---

  • Build and run your first flood model and see the results
  • Check what data you need before you start: accepted elevation file formats and coordinate system requirements

• Build out your model

  ---

  • Add design storm rainfall to your model
  • Model a culvert or bridge in your catchment
  • Refine the mesh resolution in your area of interest

• Get your results

  ---

  • Find a finished Run's results and download them
  • Work out why your Run failed and fix it

• Build trust in your results

  ---

  • Establish whether ANUGA results are acceptable to regulators, with validation evidence

• Work with AI agents

  ---

  • Connect Claude Code to Hydrata so your AI agent can drive the platform

• Run ANUGA on your own hardware

  ---

  • Understand Hydrata's scenario package format
  • Download a scenario package from Hydrata and run it yourself on Windows or Linux
  • Look up what the resolution field in scenario.json means and its units
  • Find out what friction values the model applies by default

Start with the Getting Started tutorial. It walks you through building a Scenario and running your first flood simulation, step by step.

Working with an AI assistant? Hydrata provides a native MCP server so tools like Claude Code can build Scenarios, start Runs, and retrieve results on your behalf.
