Tarna; — V The sub-catchment area of River Szamos; — VI The sub-catchment area of the Körös rivers; —

air commences because there is no side outlet at lower altitudes. As a result, there is
even more precipitation here than in the previous mountain range. Naturally, the
Maramuresh Basin sheltered from rain by the Gutâi Mountains is drier, but the riverhead
area of the Chorna Tisa behind the highest ridge is also rainless.
The drainage system of River Szamos is at a lower altitude and is much bigger
than that of the Upper Tisa. In most of the region there are low and medium height
mountains, which are covered by Tertiary argillaceous and marly strata, therefore the
sloping of the mountains is not as great as in the water system of River Tisa.
