The are two sides to the question " which type of dams are more sustainable"?
One side maintains that " small is beautiful". As viewed from top they do not mar the beayty of things on the ground. In this respect many counries including India and China have passed policies to promote them. Studies have found that they have greater impact per MW.
Both type of dams are sustainable. Everything depeends on location.The main throught should be on the resources available and the cost.
Large dams are mainly those which are higher than 18 metres. The drawback with large dams is that in many cases people are forced to vacate theiir houses and shift elsewhere. Also many dams have burst causing collosal damage.
So while both large and small dams are sustainable Governments have to weigh the benefits of both and decide which to build. Both are good.

The International Hydropower Association (IHA) launched the HSAP in 2011 as a set of voluntary guidelines for the hydropower industry to assess the social and environmental performance of hydroelectric dams. Jumping on the sustainable veggie-powered bandwagon, the IHA’s Protocol considers 19-23 relevant sustainability topics in a score-card fashion for the IHA’s license-granted consultants to check off when assessing a dam’s social and environmental criteria at various stages. Doesn’t sound so bad considering the dismal record of dams and displacement and ecological damage.
