Soil Types – Infiltration Properties
Horton parameters
We use the Horton infiltration equation for modeling infiltration in various parts of the SCALGO Live system, including the Flash Flood Map with infiltration and drainage and Core+ DynamicFlood. Each soil type in our topsoil map can have both a "High compaction" and "Low compaction" state. The compaction state of the topsoil in a given cell is determined based on the land cover, see further below.
The table below lists the Horton parameters for the soil types in the SCALGO Live topsoil map in their different states.
Soil type | High compaction | Low compaction | ||||
fc | f0 | k | fc | f0 | k | |
Rocks and boulders | 500 | 1000 | 5 | 2000 | 5000 | 5 |
Gravel | 500 | 1000 | 5 | 2000 | 5000 | 5 |
Coarse sand | 30 | 120 | 5 | 1000 | 4000 | 5 |
Fine sand | 25 | 100 | 5 | 500 | 2000 | 5 |
Coarse sand with clay | 21 | 85 | 5 | 85 | 150 | 5 |
Fine sand with clay | 20 | 80 | 5 | 50 | 130 | 5 |
Coarse clay with sand | 12 | 50 | 5 | 30 | 120 | 5 |
Fine clay with sand | 9 | 47 | 6 | 25 | 100 | 4 |
Clay | 5 | 20 | 5 | 20 | 50 | 5 |
Fine clay | 0,5 | 2 | 5 | 2 | 20 | 5 |
Very fine clay | 0,01 | 0,1 | 5 | 0 | 1 | 5 |
Silt | 20 | 80 | 5 | 50 | 130 | 5 |
Gyttja/peat | 21 | 85 | 5 | 85 | 150 | 5 |
Bedrock | 0 | 0 | 5 | 0 | 0 | 5 |

Grouping into high/low compaction
The land cover type of a given location decides whether we use the high or low compaction Horton parameters for that location, the table below details how we map each land cover type to a compaction degree.
Land cover type |
