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

• See it done first

  ---

  • Watch the whole thing done once, in 13 minutes
  • Follow the same eleven chapters in writing, at your own pace

• 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

• What will this run cost?

  ---

  • Find out what you are charged for, what is free, and when the price appears

• Watch the flood happen

  ---

  • Play a finished Run back on the map, pause it, and read depth or velocity at any moment

• Get your results

  ---

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

• Share it with a client

  ---

  • Send someone a model to look at, and control what they can see

• Build trust in your results

  ---

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

• Get help from a person

  ---

  • Ask us, and know what to send so we can trace your Run

• Work with AI agents

  ---

  • See what Hydrata's MCP server offers an AI assistant, and what it cannot do yet

• 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

New here?

Start with the Getting Started tutorial. It walks you through building a Scenario and running your first flood simulation, step by step, following the same eleven chapters as the overview video it embeds.

Working with an AI assistant? Hydrata publishes an MCP server that reads projects and scenarios and drives Runs. It is a preview: external accounts cannot connect to it yet.
