Database of design storms in Finland
Design storms can be used for example when planning urban runoff structures or as precipitation data in hydrological models. The database of design storms is based on radar measurements from Finland in 2013–2016 and extreme rain areas derived therefrom. In contrast to commonly used design storms with simple variation patterns in time (e.g. a triangle), the real momentary variations in intensity are shown in these present cases. The database contains heavy precipitation events whose statistical return period is up to three years. The table below shows several examples. The entire numerical data can be downloaded as an Excel file and all the hyetographs as PNG images.
Please select the duration of the accumulation period:
Examples of design storms with an accumulation period of 5 minutes. Start time, location (longitude and latitude), total precipitation, duration and return period are stated for each design storm. The momentary rain intensity, interpolated with storm motion into 1-minute intervals can be obtained by downloading the entire material. Clicking on the images of the examples will increase their size.
