Soil erosion--Iowa--Cedar Falls--Prevention; Best management practices (Pollution prevention)--Iowa--Dry Run Creek (Black Hawk County);
Dry Run Creek is a watershed located in Cedar Falls; Iowa and it is on a list of the state's impaired waterways. One reason it may be impaired is that there is excessive erosion in the stream. This study assessed the Bank Erosion Hazard Index of portions of the creek to determine erosion hotspots. The majority of the banks in all the branches had a Low score, meaning that the BEHI was less than 11.9. The minimum BEHI score is O and the maximum score is 40. The lower the score, the better the condition of the bank. Portions of the University, East, and West branches of Dry Run Creek were studied. All assessed stretches in the West Branch were found to have a Low BEHI rating, indicating that they are in good condition and are in little danger of erosion. The highest BEHI found in the West Branch was 10.3, putting all of the stretches in the Low category. Stretches of the stream with a Moderate or High BEHI rating were found in the University and East Branches. Most of these scores were well above 15. These areas could be considered areas with high erosion potential that should be monitored and treated with measures to prevent erosion.
