• Abstract:
  The addition or removal of flow from a stream affects the water surface downstream and possibly upstream. The extent of such effects is generally determined by modeling the receiving stream. Guidance that concisely describes how far up/downstream a hydraulic model needs to extend to fully describe those effects was developed for rapid model construction to assess changes in anticipated discharge. The “rule of thumb” enables designers/modeler to predetermine the level of effort such a model would require. A spreadsheet-based tool named BoundaryDistanceRuleOfThumb-2015.xlsm was built to make the distance estimates based on four different methods based on literature review and a generic modeling study conducted as part of this research.
