Mureş

/ Maros River

The use of river resources may directly affect the macrozoobenthos. The riverbed was deepened by 1.5-2 m at several areas due to the

unregulated gravel extraction. As a result, freatic water freely runs into the rivers.

Riverbed gravel extraction is wide-spread on the Transylvanian rivers.
