3Di floods: avoid disaster management during a flood

3Di floods: avoid disaster management during a flood

During the calculation, the user can retrieve information and make changes. These modification may relate to the spatial planning or the water and wastewater systems and civil engineering structures.

2D models of rivers and estuaries have been around for a long time, but they are too slow or too large for many applications. Putting the outer flood fields underwater or draining them again. 3Di shows the affects in case of flooding, dry periods, water transport by the river etc. All described exceptionally well in a 3Di area model. The answer to ‘What If’.

The 3Di area model also allows the effects of deeper dredging, harbour expansions and bypasses to be examined. The effects of nature development in the flood fields or the utilisation of overflow areas can be made clear to everyone.

USA analysed

3Di has been used abroad to make 2D models of Jamaica Bay in New York and San Francisco Bay. The calculation time for these models is just a few minutes, although the models contain a billion cells.

Creating an area model

The area models are generated automatically from the object database and the raster database by a 3Di specialist. The object database and the area models are stored in the cloud. All the variants of an area model are managed automatically in the cloud and it is possible to retrieve older variants.

Interactive

When a calculation is to be carried out, the user has a 3Di web interface for choosing an area model and a scenario. The user can start up a calculation with the ‘play’ button and follow the calculation on the map as it progresses. During the calculation, the user can retrieve information and make changes. These modification may relate to the spatial planning or the water and wastewater systems and civil engineering structures.
