text: In spite of the apparent complexity of the flow transition, application of simple analytic tools to a two dimensional analysis is effective in providing analytic results which closely parallel both field and laboratory results. Analysis shows:
  * Height of the jump: the relationship between the depths before and after the jump as a function of flow rate
  * Energy loss in the jump
  * Location of the jump on a natural or an engineered structure
  * Character of the jump: undular or abrupt
