The Rainfall model can be used to study the accumulation of water after heavy or long-lasting rainfall in a geographical area.

The results from a simulation will indicate not only where water accumulates, but also how long it will take to drain into rivers or the sea. This will give indications for which areas will need further analysis by geologists to uncover risk of landslide.

The solution is only available in the Norwegian market.

The Rainfall Module

The module combines simulation with data from Geographical Information System (GIS) in Powersim Studio 8.

The user may specify a rainfall profile over time and study where the water accumulates in the terrain. You may simulate heavy rainfall over a few days or look at bad weather of longer duration.

Information about elevation within the selected area is read into the model. Thus the simulation estimate where it will flow through the terrain and where water accumulates. Water is indicated with a blue colour but when the water reaches an indicated river or the sea the colour will disappear.

After a simulation, data is fed back to the GIS system, and allows for further analysis by geologists. The benefit of using the Rainfall simulation for such analysis is to uncover the risk for landslide in a much wider area than usually investigated with more thorough and costly tools. This simulation is useful for taking security measures towards existing populated areas or assess risk when making plans for domestic or industrial establishment.

This model is made with Studio 8 GIS and communicates with a GIS software called GISLine from Norkart .

The GISLine product is produced by Norkart Geoservice and is available only with Norwegian language.
