Abstract

The present STIC effort takes advantage of new innovative solutions developed through extensive research at IIHR-Hydro-science and Engineering, at the University of Iowa. Implementation of the one of the developed self-cleaning designs at one of the existing culvert sites (through retrofitting) has demonstrated its operational capabilities as well as robustness and efficiency in mitigating sedimentation over a range of flows occurring over extended time periods. The major activities of the STIC incentive funded project entail a series of workshops organized by Iowa's Local Technical Assistance Program (LTAP) to disseminate the innovative designs. Four workshops were delivered at strategically chosen locations in Iowa with the participation of the State, County, City and other public stakeholders.
