The demand of energy is increasing day after day while producing clear and renewable energy is getting more important for contemporary countries because of global warming. So, any kind of project has to be considered in terms of timing, environment, safety-security and cost. Hydropower dams provide an important source of energy in many countries for a long time. However, they have several impacts on environment, sometimes on cultural history. So, it has been the greatest dilemma in engineering projects whether to preserve historical remains and fertile farm lands or to behave in favor of hydropower generation. Implementing more professional engineering approaches and practical engineering works can remove the engineering structure from being in a critical situation.
