The Rusenski Lom is a river in northeastern Bulgaria, the last major right tributary of the Danube. Its length is 55 km but reaches 197 km if its right constituent river the Beli Lom is included.The river is formed by the confluence of two constituent rivers, the Beli Lom (147 km, left) and the Cherni Lom (130 km, right), at an altitude of 47 m in Ruse Province. It flows in direction north–northwest through the Danubian Plain in a deep canyon-like valley cut in Aptian limestones. The Rusenski Lom forms numerous meanders due to its small mean slope of 0.62 m/km. Although the length of the river is 55 km, in straight line the distance between its source and mouth is only 17.6 km. It flows into the Danube at an altitude of 16 m in the outskirts of the city of Ruse. With the two constituent rivers included, its drainage basin covers a territory of 2,874 km2.
