INFORMATION ABOUT BIOTOPE
Description of the area surrounding the biotope: The width of this river is 300-400 meters.

Description of the underwater landscape of the biotope: Pebble and rocky ground welcomes us underwater view of Filyos River.
The ground structure throughout the river is variable.
While at some points we encounter angular rocks, at some points we encounter oval and smooth rocks.
The sand of Filyos river is silica sand in beige colors.
Description of the parameters of the habitat: Measurements at different points of the river Filyos water 15 – 26 °C and pH ranged from 7-8.
The chemical water parameters:

Threats to the ecology: Problems in the Filyos River Basin partly due to natural environment and partly as a result of Human conditions
Problems arise are observed.
The problems of Fialos basin due to physical and human events
As it is possible to handle two parts. under the heading of physical problems
The problems arising from geological and geomorphological structure and hydrological features were Evaluated.
What can be done for these problems is often limited to reducing negative impacts.
The main problems that need to be solved in the field of investigation are the
It will also provide a better living environment for future generations.
A natural phenomenon that shows its effect in the field of investigation by repeating it for very short Periods is floods.
Precipitation is the most important factor in the formation of floods. In the study area, spring rainfall or Feed the river Filyos
With the melting of the snow in the mountains where the rivers take their resources, floods are seen in The Filyos stream or its branches in the summer months.
However, it is not possible to connect the formation of floods in the study area only to the excess Amount of water in certain periods.
The negativity caused by floods is increasing as a result of some activities of people.
At the beginning of these activities, filling of the rivers’ beds for various reasons is narrowing or closing.
There are many examples that can be given in this regard.
In the Upper Filyos basin, Yenice is the most affected settlement by the floods.
In Yenice, which is located in the lower ground of İncedere, filling the river bed with waste materials Prevents the flow of this river.
Environmental pollution is observed as an example of human events. this is one of the causes of Environmental pollution
One is the unconscious disposal of chemicals and waste materials from industries near the Filyos basin.
And the flood waters and wastes are mixed with Filyos River.
