This course is based on Chapter 50 of the National Engineering Handbook, published by the Natural Resources Conservation Service (NRCS). This publication provides guidance on the design of earth spillways. Earth spillways are typically constructed of soil and/or rock materials and are used to safely convey excess water from a dam or other water control structure. The publication covers topics such as spillway selection, hydraulic design, erosion protection, and construction considerations. It emphasizes the importance of spillway integrity, which is the measure of a spillway's resistance to breaching failure, and provides detailed guidance on how to ensure spillway stability and integrity. The publication also includes helpful design examples and case studies. Overall, Chapter 50 provides valuable information for engineers, designers, and others involved in the design and construction of earth spillways.
