Low head dams are better than high head dams for a number of reasons.
The article below will outline 17 of the most compelling advantages to building low head dams. 1) Low head dams are cheaper and easier to build than high-head dams because they don’t require as much concrete or steel. 2) Low-head turbines generate more electricity from the same amount of water, which means that you need less land area for your dam in order to produce the same amount of power as a conventional high-head dam. In a paper published in the Water Environment Research Foundation, it was found that “a low-head dam using [the] same water quantity as an upstream high-downstream hybrid turbine could generate up to 11% more electricity.” Low head dams also allow for much greater flexibility when choosing where your project is sited because you don’t need such steep slopes or access to higher elevations. High head turbines are also less efficient with sea level rise due to increased turbulence around the dam. Low head turbines use floodgates at the base of their gates which can be adjusted easily by operators based on changing water levels and flow rates. High heads cannot adjust their gate heights quickly enough as these adjustments have a significant impact on how
