Mitigation of Sedimentation in Multi-Barrel Culverts
The “Iowa DOT Culverts” geo-portal provides a way of informing users on the potential for inception and development of sedimentation at culverts. The portal enables users to establish the degree of sedimentation at any existing or planned culvert location. The site also aids designers and operation personnel to store, retrieve, analyze and visualize a wide range of information about culverts.
