Infiltration rate measurements

The data set contains infiltration rate measurements from nine sites representative of urban fabric surfaces.
Infiltration rates have been measured weekly over the frost-free period of one year. All sites are located in the "Kupittaanpuisto" urban park in the City of Turku, Finland. The sites include different types of urban green (grass, trees, low vegetation, swales), permeable hard surfaces like gravel paths and parking areas, tarmac, sports fields, and barren soil. A soil sample has been collected from each site to determine the soil type based on grain size distribution and organic content.

For each measurement, infiltration was measured with a METER GROUP mini infiltrometer (c) at three points within one meter around the monitoring location. The data set provides additional information about the obtained parameters.

Note: The data set comprises 13 Excel tables, one per monitoring site. Each table contains several sheets, one per measurement. The sheets are named according to the date of data collection in the format "ddmmyy" or "dd.mm.yyyy" and a number of the replicate measurement (1-3) done for each monitoring site, e.g. "170723(1)". In addition, each table contains a "Site_info" sheet that provides some information about the surface type at the monitoring site and the sites geographic coordinates (decimal degrees, WGS84). A separate folder with shapefiles, kml, and GeoJSON layers containing the sampling sites is provided.
