“…The design was based on the USDA-NRCS Code 412 Grassed Waterways (National Resources Conservation Service, 2014). Sizing the grassed waterway met the peak flow of a 10 year, 24 hour storm based on the National Oceanic and Atmospheric Administration Atlas 14 precipitation and a Soil Conservation Service (SCS) unit hydrograph (Rundhaug, 2018).…”

ACKNOWLEDGEMENTSMy thanks go out to Dr. Allen Bradley for his patience and tutelage. What I have learned from you has helped me be successful at Iowa and will continue to do so in the future. I would also like to thank Dr. Larry Weber for giving me the opportunity to come to Iowa and be a part of IIHR and Dr. Antonio Arenas Amado for working with and guiding me on a range of topics over the past two years.To my family, for helping me realize my aspiration of going to graduate school, your support is always appreciated and never taken for granted. To the friends I made while here, especially Chad Drake and Trevor Rundhaug for being close colleagues throughout the past two years, my time at Iowa would not have been the same without you. To everyone I met and worked with at IIHR, I cannot imagine a more welcoming place and have thoroughly enjoyed my time here.ii ABSTRACT Conservation practices are frequently used to try and restore the natural resilience of the landscape to retain water, decrease nutrient loads, and mitigate flooding. Quantifying the potential benefits of conservation practices can inform stakeholders and improve the effectiveness of watershed planning. To this end, an existing Hydrological Simulation Program -FORTRAN (HSPF) model of the English River was enhanced to enable detailed modeling of conservation practices. Using site-specific nutrient removal wetlands and water and sediment control basins (WAS-COBs) derived from the Agricultural Conservation Planning Framework (ACPF) two 12-digit hydrologic unit code (HUC-12) watersheds within the English River, Headwaters North English River and Gritter Creek, were selected for modeling. Wetlands drain much larger areas than ponds that currently exist in the two watersheds. Average flood peak reductions are over 50% near the wetland sites, and diminish moving downstream to a few percent or less at the watershed outlets. Many WASCOBs exist in the two watersheds, but WASCOB use is minimal in other areas of the state.WASCOBs provide slightly more flood storage than ACPF wetlands but the storage isy distributed throughout the watershed. As a result the simulations show that the peak reduction is greater than for wetlands at many locations.iii PUBLIC ABSTRACTConservation practices are frequently used to try and restore the natural resilience of the landscape to retain water, decrease nutrient loads, and mitigate flooding.
