Stormwater runoff pollution of an existing catchment consisting essentially of apartment buildings in Braunschweig/Germany.

This dataset includes stormwater runoff concentrations of pollutants (COD, TP, DP, NO3, NH4, TSS) taken from a sampling point in Braunschweig, Germany. The total catchment size is 5 ha with approximately 1.8 ha total imperviousness consisting essentially of apartment buildings from the 1970s and roads. This catchment was chosen for comparatively clear delimitation to different land uses considering location-independent results. Samples were taken as part of the research project TransMiT (https://www.transmit-zukunftsstadt.de/). More information including sampling and analytical methods are detailed in the corresponding journal paper "Dynamization of Urban Runoff Pollution and Quantity" and supplementary data, submitted to the MDPI-journal Water.

Description of fields:

- SamplingPoint:
    - storm sewer: stormwater runoff sampled during individual rain events in a storm water sewer manhole receiving runoff from the entire catchment
- SamplingTime: time of sampling during individual rain event (CET)
- COD: measured value of chemical oxygen demand (COD)
- TP: measured value of total phosphorus (TP)
- DP: measured value of dissovled phosphorus (COD)
- NO3: measured value of nitrate (NO3)
- NH4: measured value of ammonium (NH4)
- TSS: measured value of total suspended solids (TSS)
    - N/A: data not available
- UnitsAbbreviation: all data given in milligram per litre (mg/L)

The data file is provided in comma separated format ("TransMiT.csv") and contains concentrations of all samples.
