Storm water modelling in an urban environment
According to Section 103 i of the Land Use and Building Act, the responsibility for the control of storm waters in an urban area rests with municipalities. Pilot work is improving the possibilities of municipalities to assess the risks of storm water and local flooding, and to create a method for controlling storm waters. The work is producing precise material modelling the material of the Earth’s surface. This is a question of a unique end result, the production of which is as automatic as possible so that the end result is reliable.
Based on multi-channel laser scanning data, the work is producing a method of classifying the Earth’s surface, which works as automatically as possible. Classification is being done in the area of the city of Imatra. A particular objective is to distinguish between surfaces through which water can permeate and surfaces that are impermeable to water. The work is creating a repeatable, standardised method that allows classification of the Earth’s surface to be automated. The method enables the development of a tool for modelling and controlling municipal storm waters.
The fruitfulness of the work is being assessed during the work, and from feedback obtained from the end result based on the usability of materials and the method. The test work will have succeeded, if the end result enables the modelling and control of storm waters based on the method created in test work for the development of the intended tool.
