On Wednesday 19th November at the 2014 international ISIS user conference, this year held in London, CH2M HILL will be launching the long awaited version 4.0 update to our industry leading river and floodplain modelling, and real-time flood forecasting suite of software. 
Our FREE 30 minute webinar on September 10 will examine some of the most repetitive tasks in modelling and demonstrate how to efficiently utilise the extensive productivity toolkit within ISIS!
Aimed at new users of ISIS, our FREE 30 minute webinar on July 1st will introduce you to some of the capabilities within our industry-leading flood modelling software.
Over the past couple of months, we’ve taken you back to the 70s when ISIS was first developed and discussed the history of ISIS 1D. Now we’re introducing you to ISIS 2D! Many people believe it was first developed in 2009, whereas the underlying engine actually dates back to the 1980s.
Earlier this month, CH2M HILL exhibited and sponsored the Association of State Floodplain Managers conference at the Washington State Convention Center in Seattle, USA where over 1,200 flood management professionals attended. 
ISIS, developed by CH2M HILL, provides more than 10,000 users with a flexible and cost-effective tool for understanding and managing the challenges associated with flood risk and floodplain management. It is widely used by governmental entities, consultants and research establishments throughout the world.
Since early 2013 the ISIS software team have eagerly been planning and working towards the next major release of ISIS, which will see some significant enhancements and innovations as well as some new solutions joining the ISIS family. 
The one-dimensional engine at the heart of ISIS 1D has been in continuous development since 1975.  It started out as a simple 'A to B' unsteady flow solver for single reaches of channel.  The next major development included the addition of being able to simulate branched and looped channel networks with floodplains.
ISIS was first developed in the 1970s as Halcrow's ONDA and HR Wallingford's FLUCOMP, LORIS and RIBAMAN software. There are a number of different types of software built into the ISIS code, but ONDA played a key role in its creation, which is why many of its functionalities remain today.
Waveney District Council recently reported that their ISIS 2D coastal model which mapped flood risk for the town of Lowestoft from a storm surge in the North Sea was extremely accurate. Lowestoft is sited on the North Sea coast of England and is susceptible to storm surges.
The most recent development, provided as part of ISIS version 3.7 at no extra cost, is the ISIS-SWMM Link.  It has been developed to combine the functionality provided within ISIS 1D and ISIS 2D with that of the US Environmental Protection Agency’s Storm Water Management Model (SWMM).
The latest update to TUFLOW, 2013-12, provides a wide range of exciting new features, including a GPU module, new 1D structures and new output formats. Users with a valid CH2M HILL or BMT WBM technical support and software maintenance contract can upgrade to the latest release at no extra cost.
An early flood warning system typically monitors rainfall and water levels 24 hours a day, 365 days a year. During a flood, it allows emergency managers and other key responders to most effectively communicate a response and, if issued well before an event, enable people to protect property and infrastructure.
Probabilistic forecasts provide a range of possible forecast outcomes that indicate the probability or chance of a flood occurring.
ISIS is currently used as a flood forecasting solution for government bodies in six countries. It is well-suited to flood-forecasting due to its short run times and model stability, whilst still retaining full hydrodynamic capability and extensive range of hydraulic structures.
We will be holding the ‘Flood Forecasting in Early Warning Systems’ webinar on 1st May 2014 at 10:00 (BST) and 13:00 (EDT). The free 30 minute webinar (20 minutes plus questions from the audience) will discuss the use of river models within early warning systems for flood forecasting. This webinar will be useful for those involved in development of early warning systems in which flood forecasting is a key component.
The industry leading ISIS 1D solver can be linked to BMT WBM's TUFLOW software, utilising the well established ISIS-TUFLOW-PIPE Link. As UK agents for TUFLOW, CH2M HILL can provide your preferred 1D-2D solution, including local technical support at no extra cost.
This month, we explain how to find out basic, yet critical, information about an ISIS model. This is important for new users, to give a brief overview of what the model contains.
We have introduced a more flexible pricing structure which is available in GBP, EURO and USD. We publish our prices so that you know what you will be paying today and tomorrow.
In December, Dr. Konrad Adams, lead developer for ISIS, introduced the new tools and features available (release notes) as part of ISIS v3.7.
On Thursday 13th March we will be hosting the latest webinar which introduces Integrated 1D-2D Embankment/Levee Breach Modelling using ISIS. Breach modelling analysis assesses the velocity, rate of inundation and depth of flood water anticipated which can determine if a development is safe or not. 
A fluvial flood mapping study for the Grand River watershed, Southern Ontario, Canada was carried out using ISIS. The aim of the study was primarily to produce fluvial flood outlines and flood depths that can provide a better understanding of flood risk and property damages.
ISIS 1D was used to support a four mile canal restoration project on the Cotswold Canals through Stroud. The software was applied to the section due to the complexities within the channel as it is designated "main river" and has three significant feeder streams, all of which are important ecological habitats.
