Sukha Volnovakha (Ukrainian: Суха Волноваха) is a river in Ukraine, within the Volnovakha and Kalmiuske Raion of Donetsk oblast. It is a left tributary of the Mokra Volnovakha (Azov Sea basin).

Description

edit

It is 46 km long and covers an area of 451 km². The valley is V-shaped, up to 2 km wide and 40 m deep. The floodplain is up to 100 m wide. The riverbed is slightly sinuous, up to 5 m wide. The river slope is 1.9 m/km. The feeding is mixed. The ice drift is from mid-December to late February; in some years it does not freeze. Several ponds have been constructed. The river is used for irrigation and water supply.

Location

edit

It starts south of the village of Olhynka. It flows within the Azov Upland, first to the northeast, then mainly to the east. It flows into the Mokra Volnovakha on the outskirts of the village of Kipucha Krynytsia.

The town of Dokuchaevsk is located on the Sukha Volnovakha.

Interesting facts

edit

It flows through karst terrain [1]. In some places, the water flows through an underground channel for several kilometers, which is why, unlike Mokra (Wet) Volnovakha, it is called Sukha (Dry).

Tournaisian sedimentary rocks are exposed in the southern part of the Donets Basin (Ukraine), where they are dominated by shallow-water platform limestone. It is the only area in Ukraine where Tournaisian and Viséan strata is easily accessible. They crop out in narrow bands through the towns of Novotroitske, Dokuchaevsk, Styla and Kalmiuske (Donetsk oblast), where numerous natural sections along the Kalmius, Mokra Volnovakha and Sukha Volnovakha rivers have been studied since the 19th century. Most of these sections were unfortunately destroyed by anthropogenic activities. At the same time, Tournaisian rocks were discovered here by numerous flux quarries.[2]
