1. INTRODUCTION The computation of the normal depth in a roadside ditch is not very straigthforward. The computation requires the iterative use of the Manning equation (Ponce, 2014). A source of possible complexity is that the typical triangular cross-section of the roadsize ditch has different side slopes (Fig. 1). In this article, we expedite the solution by providing an online calculator specifically developed for sizing a roadside ditch.
2. EXAMPLE We use the calculator ONLINE_SIDE_DITCH to run the following typical example:
