Flood Cloud (launching in June 2017) is an innovative service from CH2M that enables users to seamlessly undertake flood risk modelling, at any scale, in the cloud. It provides users of Flood Modeller Pro and Flood Modeller Free with a new way to run 1D, 2D and linked 1D-2D flood models. Powered by the Parallel Works platform, Flood Cloud delivers the on demand computational resource required to deliver the step change needed for better information on flooding.

Until recently the required outputs from flood modelling were typically selected water levels and flood extents from a handful of simulations such as three return period events. Now, a much richer set of results are required, perhaps covering ten or more annual exceedance probabilities, with various climate change scenarios and a range of flood management options with different flood defence performance assumptions.

This, together with the move towards detailed 2D modelling, has resulted in a step change in the computational resources needed to undertake the modelling. Flood Cloud provides the answer by providing an almost infinitely scalable resource pool of processors tightly integrated within CH2M’s industry-leading flood modelling software.

Flood Cloud is seamlessly integrated within the Flood Modeller interface

Seamlessly integrated

Flood Cloud is seamlessly integrated within the Flood Modeller interface. Once a user has set up their models locally, they can send them for processing on high performance hardware in the cloud directly from within the interface.

Flood Cloud provides a dashboard to monitor runs

Interactive dashboard

The dashboard allows users to monitor the progress of their runs showing percent complete, mass balance, convergence and status. A graphical summary representing flows, iterations, convergence and mass balance is also provided.

Flood Cloud provides the on demand computational resource required to deliver the step change needed for improved information on flooding. The importance of, and demands on, flood modelling continue to increase. In order to better understand flood behaviour and identify robust flood management options, more and more simulations are required. At the same time pressures are growing to act quicker and be more efficient. Flood Cloud is designed to help you respond to all of these situations.

Example: a project may require simulations for 5 sets of inflow boundaries, at 4 epochs, with 3 climate change scenarios and for 3 flood management options – for a 2-hour base simulation run time this equates to more than 2 weeks of continuous running if one licence/computer is used. But with Flood Cloud all the 180 individual simulations can be undertaken at the same time – saving the project 2 weeks of programme.

Key benefits of Flood Cloud

  • Quicker results: access high performance hardware on demand, allowing you to unlock the full potential of Flood Modeller by running more concurrent instances of the software.

  • Greater analysis: deterministic models for single storm events have been established for decades and modellers have been limited to this method due to the cost of software, speed of computers and availability of alternative analysis. It is now practical to overcome these barriers.

  • Flexibility: perfect for organisations with growing or fluctuating project demands. If workloads increase or you need to undertake more detailed analysis, it’s easy to scale up your processing capacity. Likewise, if you need to scale down again, you have that flexibility.

  • No capital-expenditure and reduced software costs: align costs with revenues and cut out the initial cost and ongoing maintenance of high performance hardware. Having the option to run a greater number of concurrent simulations can also reduce future software costs.

  • Accessible from anywhere: Flood Cloud can be accessed when you need it, at any time, from anywhere in the world. Available 24/7, your projects can continue to run beyond your regular working day.

  • Free up existing software licences: run simulations using Flood Cloud allowing others to use the licence to build their models.

  • Reliability: hosted by Amazon’s state-of-the-art offering, it makes it less prone to in-house IT infrastructure challenges.

  • Competitive advantage: it provides enterprise-class technology, for everyone, allowing businesses to act faster and more efficiently than ever before. Our pay-as-you-go service allows organisations to compete more effectively, while remaining lean and nimble.

  • Secure: hosted by Amazon, it is built on a secure platform, ensuring your model data and personal details are safe.

  • Only pay for what you use: our cost effective pricing structure makes it even easier for you to plan and manage your projects.

Frequently asked questions

A number of frequently asked questions have been answered below. If you have any additional questions or would like to discuss Flood Cloud further, please contact your local representative

What is Flood Cloud?

Flood Cloud is an innovative service from CH2M that enables users to seamlessly undertake flood risk modelling, at any scale, in the cloud.

When will Flood Cloud be made available?

Flood Cloud is due to be launched in June 2017.

Why would I use Flood Cloud instead of a standalone licence?

Until recently the required outputs from flood modelling were typically selected water levels and flood extents from a handful of simulations such as three return period events. This information could be easily and quickly obtained using basic hardware and standalone software.

Now, a much richer set of results are required, perhaps covering ten or more annual exceedance probabilities, with various climate change scenarios and a range of flood management options with different flood defence performance assumptions.

This, together with the move towards detailed 2D modelling, has resulted in a step change in the computational resources needed to undertake the modelling. Flood Cloud provides the answer by providing an almost infinitely scalable resource pool of processors tightly integrated within CH2M’s industry-leading flood modelling software.

How do I access Flood Cloud?

You will be able to access Flood Cloud from directly within the Flood Modeller Free and Flood Modeller Pro user interface.

Who are Parallel Works?

Parallel Works is a high-tech company based in Chicago that delivers high performance computing as a service. They are building on advanced computing technology from the U.S. National Labs to make large-scale computing simple, accessible and cost-effective.

How secure is Flood Cloud?

Flood Cloud is extremely secure and leverages Amazon’s state of the art Web Services infrastructure. Flood Cloud protects cloud resources from unauthorized access, and from any un-intentional access to or destruction of user data.

Amazon Web Services has achieved ISO 27001 certification of their Information Security Management System (ISMS) covering their infrastructure, data centers, and services including Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Service (Amazon S3) and Amazon Virtual Private Cloud (Amazon VPC).

What will Flood Cloud cost?

Flood Cloud is a pay as your go service and is based on usage monitored per hour. Prices will be confirmed later in 2017.

How do I make payment?

The Flood Cloud pricing structure will allow you to purchase ‘credits’ from the Flood Modeller Suite sales team. An invoice will be raised, allowing you to make payment using a credit card or BACS.

What currency can I pay in?

We can invoice you in GBP, USD or EUR.

What platform is Flood Cloud run on?

Parallel Works is an innovative cloud platform that delivers easy access to scalable computing. Flood Cloud is built on Parallel Works, and uses Amazon Web Services to deliver the computing power.

What security procedures are in place for Flood Cloud?

Each Flood Cloud user has their own private cloud-based file storage area, not accessible to any other users. Each Flood Modeller Pro execution takes place in a private directory on a cloud computing node. This directory cannot be accessed by any other cloud user, and is destroyed when the model execution is completed.

What information will be stored within the ‘Cloud’?

This is for users to decide. Users will have access to and control over what is stored on the cloud. Basic data (username, email and password) will be stored on the Parallel Works account servers. Beyond that, users have access to an amount of persistent cloud storage for input files and results they want to keep in the cloud. Results can also download and saved, then deleted.

Will I need to transfer my models to the cloud and work off a virtual machine?

Users can send analyses to the cloud directly from the Flood Modeller User Interface. We have designed the system so you only need to define which models are to be run on the cloud – the transfer of files (upload and download), virtual machine start-up and configuration, and software licencing is done for you. Once they have run on the cloud, they will be brought back for further analysis.

How will I know if there are any problems with the simulation?

The returned data from a cloud simulation will contain all output and log files produced by Flood Modeller Pro. Selected log and output files may be streamed back to the user in near-real-time in order to determine if a run is proceeding acceptably, or should be terminated and resubmitted to address an error.

Will I be able to stop a simulation once it has started?

Yes. Users will be able to terminate a run and can use streamed output (or exceeding of expected run time) as an indicator that something is wrong with the run.

Do you need Flood Modeller Pro to run Flood Cloud?

Both Flood Modeller Pro and Flood Modeller Free provide access to Flood Cloud.

It you have an existing model that exceeds the restrictions of Flood Modeller Free and you do not have access to Flood Modeller Pro, you will still be able to run this model using Flood Cloud. However, you won’t be able to make changes or updates to it.

Can I run TUFLOW and Flood Modeller-TUFLOW linked models in Flood Cloud?

Yes, Flood Cloud will allow you to run Flood Modeller Pro 1D, 2D and 1D-2D linked models. It will also enable users to run Flood Modeller (1D)-TUFLOW (2D) models as well as TUFLOW only models.
