The simplest is the process of draining the land. This is due to the fact that you do not need to take into account the rules of landscape design and it will be quite easy to establish surface drainage yourself. You must first draw up a diagram through which the channels will be dug up. At the same time, they must have such an angle of inclination so that all the water accumulates in one place, and so that the trench does not crumble, for which it will be enough to fix its edges with a net.
