Consulting engineer and software distributor Waterman IT has announced enhancements to its hydraulic modelling programme, 12d Model.
12d Model makes it possible to input survey data directly to the hydraulic model, removing the need for lengthy manual data inputting. Isis, for example, involves interpreting survey maps and inputting point levels. Instead, survey data - either from an electronic distance meter or aerial laser survey equipment - can download directly into the model. It can also use the information itself to create three dimensional digital terrain maps with contours, making interpretation easier for the user.
The digital maps can be used after modelling has been completed, illustrating how the water rises over its banks and moves into the floodplain.
Waterman IT sales manager Ed Wilson says: 'The model allows river engineers to progress quickly from survey reduction to hydraulic modelling and on to visualising a completed project with a major flood event for example a 100 year storm.'
'Three dimensional animated movie files are easier for many people to understand than traditional inundation maps and these are quickly produced once the hydraulic analysis is complete.'
The enhancements to 12d Model include automated production of engineering drawings from the flood hydrographs and use of three dimensional images in movie files showing inundation in the project area.
Waterman Civil & Transportation (WC&T) has been using 12d Model for several years and has incorporated flood models into more traditional roads and services engineering projects.
Using 12d Model's latest enhancements with flood modelling package HEC-RAS, the Waterman team has been able to produce numerous 'what-if' scenarios quickly, resulting in a more accurate long term model.
