The surface and subsurface drainage systems developed in the Moldova River watershed in the County of Suceava have been designed to be used on drainage sectors, and, in order to enhance excessive water capture and discharge, several complementary works have been planned from time to time, namely: land levelling, shaping, deep loosening etc. Due to the extension of the private ownership of the land with drainage systems starting with 1991 and due to the carrying out of soil works on individual plots of land, the land was shaped in the bedding with ridges and furrows, of variable widths, level differences and transverse slopes. Land shaping that does not match the routing of the plastic drain lines and of the drainage network allows the water to stagnate in the furrows and extend the excessive humidity period. The use of the developed areas on drainage sectors facilitates the levelling of small depressions and supports the even removal of excessive water. As maintenance works have not been performed from time to time, this has gradually led to the erosion of slopes and to the slitting of the canal network and of the discharge holes in the drains, which caused excessive humidity to reoccur.
