Cummins Falls State Park is host to thousands of visitors hiking down to the stream bottom and up the gorge to the falls. Dangerous flash flooding caused by heavy rains are of concern. Since October 2019 a state installed rain and stream gauge system monitors the watershed for rainfall accumulations and stream rises. The purpose of our study is to analyze the data captured by the monitoring system compared with a hydrologic model developed in HEC-RAS. We seek to determine rainfall amounts posing a problem for the park and how long for heavy rains to move through the watershed. The data of stream stage and rainfall was processed to observe trends between rainfall and stage. A HEC-RAS model was built of the lower West Blackburn Fork and lower East Blackburn Fork merging into the Blackburn Fork continuing to the area below the falls. This model is in refinement for accuracy, but will run some simulations. No predictions are assessed from HEC-RAS yet, but with refinement and the addition of rainfall HEC-HMS models, we plan to run varying storm situations to predict rises and travel times in the future. Since November, updates to the monitoring system enabled us to observe one rapid rainfall event and graph the results. From these results, we can conclude that once final calibrations are performed, the rainfall and stream gauge system will give the park time to lead visitors from the areas below the falls before flooding occurs, thereby increasing the enjoyment of Cummins Falls.
