BOOK OF ABSTRACTS Tuesday, Monday, October 27 23 Poster Session 4:45–5:45 Water: Recycle, Reuse, Protect the Environment, and Save Money Michael Jungbauer, Landform, mjungbauer@landform.net In an age of diminishing fresh water supplies, battles over water allocations, and increasing regulations on every aspect of water, practitioners need real tools and real information on available solutions. Business as usual will continue to drive us to the brink of impending water disasters as we’ve seen in other parts of the country. This presentation is focused on providing the tools necessary to start planning for the future, based on technological solutions that are proven and available today. A variety of solutions that are available for use in residential and commercial applications that can be applied to stormwater, wastewater, and lake restoration projects will be covered. The bio-chemistry associated with water problems is also discussed. Detailed topics include utilizing the existing hydrology and geology of a site in an effort to place treated water into rapid recharge areas to facilitate recharging the aquifers, as well as cities using intentional zoning to locate businesses such as car washes, laundromats, and greenhouses that can reuse recycled water. Technology is available today that is economical and is already being used on sites around the country. The goal of this presentation is to provide long term solutions that are available now and can be used to recycle, reuse, protect the environment, and save money. Development of Riverbank Stabilization Guidance for the Mississippi River Dan Kalmon, Mississippi Watershed Management Organization, dkalmon@mwmo.org; Jeremy Grush, LimnoTech; Hans Holmberg, LimnoTech; Todd Redder, LimnoTech; Todd Rexine, Great River Greening The Mississippi Watershed Management Organization (MWMO) is developing a riverbank classification system for the Mississippi River upstream of Ford Dam. Physical characteristics of the riverbank, along with predicted shear stresses across a full range of flows, will be used to classify and recommend bio-engineering applications to restore and protect the riverbanks. This presentation will describe the field survey and data collection, modeling, and data synthesis efforts being conducted to support this project. Field surveys are being conducted to collect information on bank profiles and slope, vegetative cover, soil type, and existing structures or protection measures. Two-dimensional hydrodynamic modeling of the Mississippi River from the Hwy 694 bridge to Ford Dam has been conducted to assess shear stress and critical bank elevations. A data management and visualization tool is also being developed to allow property owners to select locations, review physical data and modeling results, and choose from applicable bio-engineering applications for their site. 43 Minnesota Water Resources Conference, October 27–28, 2008
Poster Session 4:45–5:45 BOOK OF ABSTRACTS Tuesday, Monday, October 27 23 Regionalization of Ground Water Systems in Support of Water Resources Sustainability Atlases in Minnesota Roman Kanivetsky, University of Minnesota, kaniv001@umn.edu; John Nieber, University of Minnesota; Boris Shmagin, South Dakota State University; David Mulla, University of Minnesota; Heidi Peterson, University of Minnesota; Francisco Lahoud, University of Minnesota Organizing knowledge for water resources sustainability requires a new approach in regionalization of terrestrial hydrologic system. We propose an approach based on a definition of the hydrological unit as the land area that integrates all components of the terrestrial hydrologic system. Such nomenclature provides not only a much fuller characterization of the hydrologic system than using just the component parts such as aquifers or confining beds, but it is also a prerequisite to study water resources sustainability. The hydrologic response of such hydrologic units, once established based on measurements at an appropriate scale, can be directly related to the hydrologic response of geometrically similar hydrogeologic units elsewhere. This similarity allows the scaling (up or down) of hydrologic response based on the absolute size of the unit. Soil Seed Bank Analysis of a Drained Peatland in East-central Minnesot Pre- and Post-Grading: a Case Study for Wetland Restoration Allyz Kramer, SEH Inc., akramer@sehinc.com This study evaluated native seed bank viability in a peatland subjected to prolonged drainage for sod production in Ham Lake, Minnesota. The study area was within a proposed wetland restoration and mitigation site, and included assaying the soil seed bank prior to, and immediately after, site grading. The goals of the study related to wetland restoration and future management activities were to quantify viable plant species present in surface and subsurface seed banks; evaluate native origins of viable germinants; and, determine relative densities of viable hydrophytes in the seed bank. Both assays included a high density of weedy species associated with moist, disturbed sites and waste places, which provide a strong argument for scraping and removing extant vegetation prior to attempting native vegetation reestablishment. Spreading surface soils around the site during grading activities should be avoided because of relative densities of undesirable weedy species contained in surface soils.
