How are buildings represented in flood modeller free?

Ive looked for infomation regarding how buldings are represented within flood modeller free, ive read that water flows around buildings and assume that it takes the 'stubby building' approach by increasing the boundary of a building by a certain amount. However, I cannot find any technical infomation or infomation atall about the process flood modeller takes. Any sources to infomation would be greatly appreciated.

 

Thanks, Josh

Hi, I have a doubt, the 1D model uses a dynamic, diffuse, and kinematic wave? Maybe a short explication.  

I don't find any information in the manual,. Thanks!.

As you have hopefully already seen in the recent Flood Modeller newsletter, floodmodeller.com will be down for maintenance from 6pm BST today (Friday 2nd June) until 8am on Tuesday. During that period, there will be no access to downloads, to the forums or to our online support system. Sorry for any inconvenience this may cause.

You can continue to contact our sales and support teams via email and telephone as normal.

Hello everyone – my question today is if anybody knows about a brief description of he basic facts about Flood Modeller in GERMAN…(short hydraulic & mathematic background)? I have to add a „breakdown“ of the software to a technical report for the authorities. Thanks for any suggestion – Best regards, Thomas

ReFH2 Unit

Hi All,

 

Slightly frustrated this morning as it appears the introduction of the ReFH2 unit now means that we must have ReFH2 installed on every machine which we need to run a model (using that unit)on!  Am I missing something or is this really the case? The unit only appears to generate the hydrograph at the time of running the simulation, thereby requiring each machine to have a license to run a ReFH2 simulation.  

We've paid to be able to generate hydrographs, must we now also pay for every modelling machine to run the simulations? Or hopefully, I have missed something.

Landslides into rivers

Any suggestions about how to model a landslide into a river?  We are looking at an area where local residents believe that the sudden failure of a a length of river bank (very approximately 100m x8m high x 5m wide) during a flood event, led to overtopping and subsequent rapid failure of embankments on the other bank leading to significant property flooding.  There are obviouly other mechanisms by which this could have happened, but I'm curious if anyone has any suggestions of how to assess this, other than the obvious, that if the model calibrates without a sudden failure we don't need to look for other factors.

UK Design Rainfall Profiles - differences between FloodModeller and ReFH2?

We've found that we get different rainfall profiles depending on whether these are produced in FloodModeller (say, using an ReFH boundary) or in other software (InfoWorks ICM and ReFH2). 

This graph comapres the results for 1:5yr 1hr summer event, scaled to give a total rainfall of 1, for profiles from InfoWorks ICm, FloodModeller using a ReFH boundary unit, ReFH2 using FEH99 parameters and ReFH2 using FEH13 parameters.

Anyone have any idea why these are different?

Flood Modeller for A Level Geography Students

I am looking at the possibility of using Flood Modeller to create models which could be used with A Level Geography Students. 

 

The Exam requirements for A Level Geography are changing next year, to a more Systems based, whole catchment based approach to rivers, as opposed to simple changes along a rivers course. As fieldwork, students would look at a small catchment and consider inputs, transfers, stores and outputs to that system and resultant issues, including flooding.

They will take measurements of the river channel, including calculations of mannings n, and consider impacts of inputs on maximum flow.

I would like to create a simple model, max 5km of channel length, and around 10 cross sections, to explore the flood risks within that small catchment.

Not being a modeller i dont know much about doing that, i have seen isis in use before and think it could do that - but some words of wisdom and pointers to help would be VERY welcome.

Many Thanks 

David Morgan

To coincide with the launch of Flood Modeller, we have set up the Flood Modeller forum. It's a great place to pose questions to and learn from other members of the Flood Modeller community.

We have also launched a new YouTube channel, with some great 'getting started' videos, with more content being added all the time.
