1.Dam site features:

The topography of the dam site, the geological structure of the basin and the slopes, the power of carrying, possible faults, cracks, alluvium thickness, full weir location and capacity, derivation conditions, transportation situation, dam distance of the material to be used in dam construction,

2. Lake area features:

The topography and geological structure of the lake area, types of rocks, the thickness and impermeability of the rocks, the features of the lake area such as water retention, the stability of the lake slopes and the landslide condition are examined.

3. Hydraulic and hydrological characteristics of precipitation basin:

The hydraulic, hydrological, meteorological and morphological characteristics of the precipitation basin should be investigated. Depending on the precipitation flow relationships in this framework, the amount of material flow, sediment accumulation, infiltration, evaporation, stream drainage system and vegetation cover of the river are examined.

4. Settlement, expropriation and costs associated with the renovation:

Dam reservoir and settlement areas, industrial facilities, agricultural land, transportation roads, etc. that will be inundated in the region will be investigated.

5. Environmental impact:

The effects of the dam on the climate and life conditions of the region, the protection of the groundwater balance for agriculture (salting), the submergence of historical sites and the deterioration of the natural structure of the region are examined.
