2. What is a dam?
A dam is a barrier built across a stream, river or estuary to hold and control the flow of water for such uses as drinking water supplies, irrigation, flood control and hydropower generation etc.

3. Classification of dams:
Dams are classified on several aspects, some of the important aspects are as follow:
Based on Hydraulic Design:
Over flow dams (e.g. concrete dams)
Non over flow dams (e.g. embankment dams)
Based on Structural Design:
Gravity dams
Arch dams
Buttress dams
Based on Usage of Dam:
Storage dams
Diversion dams
Detention dams

4. Classification of dams:
Based on Construction Material:
Concrete / Masonry dams
Earthfill dams
Rockfill dams
Earthfill rockfill dams
Concrete faced rockfill dams (CFRD)
Based on Capacity:
Small dams
Medium dams
Large dams

9. Parts of a dam
Dam body: Body forms the main part of a dam as an impervious barrier
Reservoir: It is the artificial lake behind a dam body
Spillway: is that part of a dam to evacuate the flood water from reservoir.
Water intake structures: is a facility to withdraw water from a reservoir.
Sluiceway: Gerektiğinde baraj gölünü tamamen boşaltmak, dolusavak kapasitesini azaltmak, akarsu mansabına bırakılacak suyu salmak amacına yönelik tesisler.
Diversion facilities: To redirect the streamflow from construction area

10. Determination of dam location
Characteristics of dam location:
Geologic formation
Spillway location and capacity
Diversion conditions
Sediment condition
Transportation facilities
Structural design
Availabilty of meterials

11. Negative impacts Imbalance of the ecosystem
Decreased amount of downstream water
Spreading of some water-born diseases
Reduction in the fertility of farmlands
