Abstract:

The Ohio Department of Transportation (ODOT) employs rock channel protection (RCP), also known as riprap, to manage energy dissipation and prevent scouring at culvert and storm drain outlets. The design for RCP at outlets follows guidelines outlined in Figure 1002-4 of ODOT's Location and Design Manual Volume 2, incorporating specifications from ODOT Construction and Material Specifications 601. RCP types (Type A, Type B, and Type C) are determined based on size, with specifics such as type, length, and depth guided by pipe diameter and outlet velocity as shown in Figure 1002-4. This design method, established by ODOT in July 1968, is still used to calculate RCP dimensions. However, the origins of this methodology and the basis for Figure 1002-4 are unclear, prompting a review of current procedures or adoption of a new methodology to ensure proper RCP sizing at conduit outlets due to ODOT's relatively less conservative approach. The research team conducted scaled hydraulic modeling and identified hydraulic conditions that impact RCP lengths, including factors not considered in previous studies.
