The Iskar (Bulgarian: Искър; LatinOescus) is the longest river in Bulgaria, a right tributary of the Danube. It has a length of 368 km. After rising in the north slopes of the Rila Mountain, it is used to form the Iskur dam - the biggest in Bulgaria. The river runs near Sofia and passes through a gorge in the Balkan Mountains with beautiful rocky forms. It flows in the Danube near the village Gigen. Latin is the language originally spoken in the region around Rome called Latium. ...

The Iskar Gorge - as it is commonly known - is a true pearl in the tourist necklace of Bulgaria.
Several kilometres later one is struck by the awesome sight of the Ritlite, which serve to outline the border between the main Stara Planina chain and the rather modest forms of the Pre-Balkan.

The IskarRiver starts in the Rila Mountain, runs through the Samokov kettle, enters the Pancharevo defile, passes through Sofia kettle, reaches the Balkan Mountain (whose beginning region is known as Kourilo threshold) and continues north.
We confirmed the published data (for another regions concerning the discussed problem) that also in IskarRiver valley changes of the petrographic composition of alluvial clasts are due to the changes in the geological structure of the feeding catchment area and of the rate of weathering of the exposed rocks.
Established reasons for the change of the alluvial clast petrography along the studied part of the Iskarriver valley (which are a result of its behavior being a self-regulating dynamic system) are valid for the valley parts of other rivers of similar structure and evolution, as well accordingly the author.
