Which type of Dam construction is preferred for Power generation?
Found a source for you! Apparently many factors come into play when constructing a dam for hydropower generation.
https://www.sciencedirect.com/topics/engineering/dam-designAt a time when appropriate dam sites are becoming more difficult to find, sustainability of hydropower may be preserved only if long-term sediment management is regarded as a key concern and objective from the early stages of dam design, dimensioning, and construction, as well as during the whole life span of the reservoir through proper maintenance and operation rules.
There is no universal strategy to achieve these goals, but an optimal combination of structural and nonstructural measures need to be identified on a site-specific basis. Although highly specialized expertise (in hydrology, sedimentology, hydraulic engineering, etc.) is absolutely necessary to understand, quantify, and master the complex turbulent flow and sedimentation processes involved, skilled technical experts also need to account for the more global scenario incorporating all other issues of a successful integrated management of the river basin. The impact of the impoundment on the long-term geomorphology of the water course should also be accounted for, considering even possible ultimate dam decommissioning.
