1. Topographical situation of the dam site:

The topography of the dam site is the first criterion to be taken into consideration in the selection of the dam type.

2. Foundation and geological structure:

The foundation condition of the dam site is not suitable for each dam type.

3. Location and type of suitable material to be used in dam construction:

There are three types of natural materials required for dam construction. These are aggregate for rock, concrete for soil, filler and riprap for filling.

4. Transportation facilities :

If the dam site is close to existing roads, which reduces the cost of new road construction. Access to the material quarries is also important when selecting the dam site.

5. Translate (derivation) conditions : In order to be able to construct the dam under dry conditions, the upstream and downstream sides of the construction site should be suitable to be closed with low dams called altitude.

6. Full spillway capacity and location

7. Earthquake

8. Climatic conditions and duration of construction

9. Landslide:

Large waves can be created from ground slopes of the dam to the landslide and the lake.

10. Economic situation of the country

11. Machine park area availability, types and capacities of machines
