The morphometrical and morphographical analysis of the Gilort drainage area represents the starting point in emphasizing certain issues related to the genesis, the stages, and the dynamics of the relief evolution within this basin. The hypsometrical step of 200 m-300 m, which corresponds to the piedmont hills and to most of the sub-Carpathian interhill depression, holds the highest rate (26.35%) of the basin surface of 1,358 sq km; then, it follows the 300 m-400 m step (19.85%) corresponding to the low sub-Carpathian area (the northern side of the interhill depression). The Gilort presents the largest valley couloir among all the tributaries of the Jiu River (about 191 sq km). The drainage density (0-6.27 km/sq km), no matter the morphostructural unit where these values appear, can be justified by the morphogenetic features of each subunit (levelled surface, glacial cirque, torrential valleys with slopes strongly affected by gullying, depression areas, and areas with friable rocks.
