Abstract:

Use of physical models to study the hydraulic jump or submerged roller action created as water overflows low head dams provides an opportunity to develop design criteria for various structure configurations for small sums of money. Low head dams, although very attractive to visitors, can be treacherous due to the unseen, violent and submerged hydraulic undercurrent. Several models of the proposed low head dam for Riverside Park in Grand Forks, North Dakota were constructed and tested in the hydraulic laboratory at North Dakota State University. A cascade structure, although the most expensive, was recommended due to safety considerations.
