We would like to thank Referee #2 for their comments and suggestions. We hope this response will address their suggestions and lead to an improved manuscript. General Issue #1, testing of low and high flow events within 1-D hydraulic models has previously been completed. This paper aims to improve the accuracy and computational efficiency of the AutoRoute model in simulating low-, medium-, and highflow events. AutoRoute is somewhat unique as it has been applied at the regional-to continental-scale by the U.S. military, but has only been tested against high-flow events (Lines 50-54 and 79-82). We agree with the referee that 1-D hydraulic models often
