Maybe 1 m deep (classified as "extremely deep", one assumes for the rainforest).
There is clay under it so it does not absorb any more than this.
However, deforestation dramatically reduces the absorption of the soil. It drops off precipitously. The way they deforest makes it worse, as they burn everything, burning up and destroying the organic material in the soil (this absorbs most of the moisture like humus). Also, with the trees, the deeper soil becomes dry through evapotranspiration, while the upper soil evaporates. If there are no trees, the lower soil stays saturated/wet much longer. Should disaggregate the layers!
This may need to be separate for each layer as the soil is slightly different.

I don't need to use land area here because it cancels out in the calculation. Rain x area / Soil depth x area (cubic meters of water per cubic meter of soil) = rain/soil depth as the area is the same!

This should be based on average temperature and humidity.
