● Tile Lines: Lines (Fig.4) were identified using Google Earth and the knowledge of the farmers, Jeb Barzen gave us use of his map of the tile lines.. ● Soil Types: The USDA Web Soil Survey(Fig. 6) was used to identify the soil types across the Engeseth - Rinde property. ● Digital Elevation Model: LiDar data for Rice county was taken from the Minnesota GIS database. Using Google Earth we created a polygon of Engeseth - Rinde(Fig. 1) and then added it over the LiDar data. ● Flow Direction: To create a flow direction map(Fig.3), we used our DEM and a hydrology package on ArcMap to run a flow direction analysis. ● Flow Accumulation: To create a flow accumulation map (Fig. 2), we utilized the flow direction map and then ran a flow accumulation analysis in ArcMap. ● Sink - The sink map (Fig. 5) was made using the hydrology package on ArcMap using the flow accumulation and direction maps. ● Buffer Strips: We researched the effects of buffer strips on agricultural lands and the positive benefits vegetated areas have with regards to quelling erosion We would like to acknowledge the assistance of several people in the development of our analysis and conclusions, including the guidance of Professor Kathleen Shea, Don Nelson and the DNR for their resources and expertise, and the assistance of the Schrader family whose knowledge of the land and openness to visits and questions allowed for us to develop more consise conclusions. Acknowledgements Methods Hydrology & Buffer Strips Analysis at the Engeseth Rinde Restoration Site Tom Knee, Toby Martin, Gabriel Coleman, and David Mayhall, ES 399, Spring 2017, St. Olaf College, Northfield, MN Hydrological processes are incredibly important to consider while restoring a given area. The way in which water interacts with land heavily influences both abiotic and biotic factors. Our study focuses on four main factors that tie in to hydrology: tile lines, vegetated buffer strips, soil types, and GIS analyses of the plot. Tile lines alter the way in which water flows on the land as do vegetated buffers. The GIS analysis will allow us to make recommendations that would otherwise be unobtainable through remote sensing data manipulation. Finally, soil types are known to vary and this variation can be drastic across a plot of this size. The objectives of our project are as follows: ● Create hydrology maps for DNR use as they continue the restoration project ● Study literature to make recommendations with regards to the tiling in the field, the potential for buffer strips, and the differentiation of soil across the property Bibliography 1.
