International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B-YF. Istanbul 2004 permitted according to strong substructure and obtaining drainage of surface water. 5. Inactive Zones: Topography is almost smooth. Settlement should be permitted according to obtaining drainage of surface water. Otherwise slips and flows may occur. 9. RESULTS AND SUGGESTIONS The study region is very risky because of its geological formations, climatic attributes, and high amount of slopes. The other reasons are: 1. Tectonic movements at the North Anatolian Fault zone effects the landslides. 2. Inclination of the study area is very effective on the landslides. 3 Because of Black Sea climate, amount of rain is very much, and it increases the relation between water and underground units. 4. Churn waters and irrigation waters make extra load on the slopes. Because the daily temperature difference is high, water in splits freeze and melt. 6. Slope of the study area to effective on occurring landslides.

Risk Map of the Study Area Before the suggestions for preventing landslides; it is useful to investigate the expense for covering the damage of a landslide: 1 % Engineering, 1 % Nationalisation, 20 % Re-construction, 38 % Restore, 40 % Losses and indirect costs (Schuster, 1986). It is clear that, expenses of preventing or correction of landslides are more economical than the after-costs. Successful precautions depend on complete and true knowledge. Risky zones should examine technically. For this region these suggestions should be exposed: l- Analysis of stability of slides and slopes should be done. 2- Slopes by the roads should be planned carefully. 3- Drainage of surface and underground water should be done. 4- Changing of plant cover should be prevented as far as possible. 5- Rock mines should be far away from risky landslide Zones. 6- Churn water should attach to sewer system. 7- Alternative irrigation methods should apply. 8- First degree zone should afforest. 9- Settlements should be constructed according to risk coefficient. 10.
