Culvert inlets and outlets
To improve the process of defining culvert inlet and culvert outlet losses for an InfoWorks network, a new field - Culvert code - has been added to their properties. This code is based on the culvert shape and material, and inlet and edge types, as defined in the Hydraulic Design of Highway Culverts, Third Edition, published by FHWA. When a code is selected, the values for K, M, c, Y, and Inlet headloss coefficient (Ki) fields are automatically populated if the #D flag is set on those fields. Previously, you could only manually enter these values. Note that for a culvert outlet, the Culvert code field is only displayed when its Reverse flow model is set to INLET.
