In the Black Sea Region, cracks occurred on the 542 km long Black Sea Coastal Road, which was opened for transportation in 2007. In order to prevent rainwater from seeping through the cracks seen at the Trabzon, Rize and Artvin crossings of the Black Sea Coastal Road, which was built on the sea embankment, the gaps in the asphalt were filled by the highways teams.
The crack repair on the approximately 8 km section of the asphalt road in Iyidere district of Rize has been completed. Experts pointed out that cracks occurred on the roads with coastal erosion caused by drawing sand from the sea floor near the shore, and warned.

REASON: SAND DRAWING
Prof. Dr. Karadeniz Technical University (KTÜ) Engineering Faculty Civil Engineering Department Head of Hydraulic Division. Dr. Ömer Yüksek said that the reason for cracks on the roads is to draw sand from the areas near the shore.
High said:
* We can not say what has to do with the shore of 100 meters of sand. Over time, the sand we take from here will fill itself in a way that nature. If he does not find enough sand this time he will try to carve the shore and underneath the roads from time to time.
* No matter how hard you make the superstructure of the road, cracks and cracks will occur over time. It is important to carry out technical analysis while granting the coaster to draw sand.
* It is necessary to determine when, how much and how to buy materials. If you interfere in nature from anywhere, you will surely come across as a negative effect elsewhere. Deniz does not put what is done to her.
ERUZ: DANGER MAY CREATE
Karadeniz Technical University Sürmene Faculty of Marine Sciences Faculty of Marine Sciences and Technology Engineering Assoc. Dr. Coşkun Eruz also explained that if the sand is drawn from the sea, the deep seas fill the gaps at the bottom with the beach sand. Eruz continued as follows:
* There is no space at the bottom of the sea. Those spaces will be filled with the effect of wave and current. If you do not use the balance there well, if there is a slime-shaped structure in exchange for the space formed there, a landslide-like seabed movement may occur.
* If serious gaps are created, if excessive sand is transported from the shore, partial danger may occur.
WHAT IS THE EFFECT ON FISHING?
Pointing out that pulling sand from the sea floor can damage the nesting and feeding areas of bottom fish such as whiting and red mullet. Dr. Eruz said, “Before the allocation of these areas, it is necessary to examine how ecologically it can harm fisheries and how it will harm the bottom ecology and decide accordingly. Because, if it is damaged, it is not possible to affect fisheries and fisheries in that region in the long term ”.
BLACK SEA COAST
Transportation is provided to 6 provinces, 64 districts, 17 parish centers, 9 ports, 3 airports and many settlements, starting from Samsun and ending at the Sarp Border Gate of Artvin, with a 542 km long Black Sea coast. During the construction of the road, 138 million cubic meters of excavation-fill, 180 million tons of fortifications and 3 million cubic meters of concrete were produced.
On the Black Sea coastal road, which costs about 4.2 billion dollars, there are 263 bridges, 12 single tube tunnels with a length of 41 kilometers, 20 double tube tunnels with a length of 18.5 kilometers. (DHA)
