Example
There is a danger of soil erosion if the ridges are overtopped and break so that the water temporarily stored in the depressions is suddenly released.
Additional information
in flat lands with drainage problems under the surface layer, it is advisable to plant the olive tree rows on top of ridges made with soil from the surface layer, making sure that the soil does not get mixed with material from lower layers that may be inapt for drainage.
