Investigating Erosion under Perennial Ground Cover (PGC) Using a Rainfall Simulation Experiment

<p>What?</p> <p>A rainfall simulation dataset measured in the field under the Perennial Groundcover system compared to four other treatments contained 9 variables with 307 columns for the infiltration experiment, 8 variables with 15 columns for the runoff and sediment data, and 5 variables with 75 columns for the volumetric water content data.</p> <p><br>Why?<br>As part of the ecosystem service modeling effort on the RegenPGC project, we carried out rainfall simulation research to quantify runoff and erosion needed to calibrate the model. In addition, data on the steady-state infiltration rate for each of the five treatments and the volumetric water content before the start of the rainfall simulation experiment were collected.</p> <p><br>How?<br>The data were primarily collected in the field at the Sorenson Research Farm, Iowa State University, near Ames, Iowa (coordinates 42° N, 93°46' W). The runoff samples were further processed for sediment analysis in the Water Quality Research Lab, Agricultural and Biosystems Engineering Department.</p> <p>CRediT: conceptualization, OSO, ALK; methodology, OSO; data aggregation and curation, OSO; formal analysis, ALK; supervision, ALK; funding acquisition</p> <p><br>Acknowledgment: The data collection for the research was jointly funded by the RegenPGC project through the Agriculture and Food Research Initiative Competitive Grant no. 2021-68012-35923 from the USDA National Institute of Food and Agriculture and the ISU Water Security Initiative.</p> <p> </p>
