Map 02.13.1
2.13.1 Surface Runoff from Precipitation
  Map 02.13.2
2.13.2 Seepage from Precipitation

Explanations and Imprint of the Map
  1. A complex model for the calculation of surface runoff (overland flow) and seepage was developed and programmed by the Berlin Federal Institute of Hydrology. The calculation procedure uses data from the Environmental Information System. First the total runoff (precipitation minus evaporation) was determined for the approx. 25,000 individual areas and then surface runoff and seepage were determined.
  2. The amount of water percolated is particularly dependent on vegetation, soil, size and type of sealing, and the degree of connection of sealed surfaces to the sewer systems.
  3. The glacial marl flat uplands discharge part of seepage underground into bodies of water. This is discharged as surface water. This amount does not reach groundwater.
  4. Areas with near-surface groundwater have greater rates of evaporation because of capillary rise of groundwater into the soil zone influenced by evaporation. If real evaporation exceeds precipitation, then groundwater depletion occurs.
  5. There is no information available on whether some highly sealed areas discharge rainwater into the sewer system. For this reason, the entire runoff for these areas is depicted in the maps as seepage. The degree of sealing and the size of runoff make it improbable that the water actually percolates.
  6. Seepage and surface runoff of streets is allocated to the bordering blocks and calculated and depicted with them.

  Map 02.13.4
2.13.4 Seepage from Precipitation
without consideration of surface sealing

Explanations and Imprint of the Map
  1. This map portrays the seepage by precipitations on unsealed surfaces. The given values refer only to the unsealed part of the blocks and block segments. With this value it is possible to derive the different capability of soils. The value can be taken as criterion for the valuation of soils for soil protection programms or for the evaluation of interventions following the nature conservation law. For water-economic questions and in context with the calculation of seepage the influence of sealing and the sewage system has to be considered as a crucial influence on the water supply of urbane areas (cf. text to maps 02.13.1-3).
  2. The calculations were made (as with map 02.13) using the complex drain model "ABIMO" developed at the Federal Institution for Hydrography in Berlin. The procedure assesses data from the Information System City and Environment. Calculations for approximately 25,000 different areas were made with the assumption that all surfaces were unsealed. Again, street surface areas were not considered.
  3. The percentage of seepage resulting from precipitation is above all dependent on the vegetation, the soil and the depth to groundwater.
  4. Areas with a high ground water level are susceptible to additional water loss due to the capilliary effect which pushes ground water up into a higher evaporation zone. If actual evaporation is higher than precipitation this leads to water depletion.
