How these factors affect drying

SoilGravelly sandy

About 19% of this ground is rock fragments, so water runs through it faster than the soil type alone suggests. It dries quicker than plain sandy. The soil type here is classified, but the exact drying speed is modeled from that classification rather than measured directly at this spot.

CanopyPartial 45%

A mix of sun and shade. Conditions vary across the network, with open sections drying faster than covered ones.

TerrainSheds water

Water runs off this terrain rather than pooling, which helps the surface dry out after rain.
