The design of stormwater control measures is often performed using the total impervious area (TIA) in a watershed. Recent studies have shown that a better parameter for these designs is the āeffectiveā impervious area (EIA), or the portion of total impervious area that is hydraulically connected to the storm sewer system. Methods to improve estimates of EIA are not highly researched, and need further investigation. The overall goal of this project is to develop a method to estimate EIA in urban watersheds with data that is readily available. First, the existing rainfall-runoff method was improved by reducing the uncertainty associated with EIA estimates and applying it to 40 gauged urban watersheds with different sizes and hydrologic conditions, mostly in the Twin Cities metro area of MN and Austin, TX. The results are then utilized to develop a new method based on the integration of GIS and Curve Number (CN). The GIS-CN method is applicable to un-gauged watersheds and is able to estimate EIA fraction based on TIA and hydrologic soil group (HSG). The results are used to evaluate the potential and the limitations of the GIS-CN method. The outcome and applications of this study improves the rainfall-runoff modelling in urban watersheds and will eventually lead to the design of a more sustainable urban stormwater infrastructure.Item ERTS-1 Applications to Minnesota Land Use Mapping. Report No. 3.(Center for Urban and Regional Affairs, University of Minnesota and Minnesota State Planning Agency., 1973) Brown, Dwight et al.Item Geographic Information Systems: A Feasibility Study for the City of Duluth Police Department.(1993) Tobin, Graham A; Fleischman, William A; Kroll, KarenA Geographic Information System (GIS) does not currently exist in the Duluth Police Department. The objective of this project is to determine the feasibility of employing a GIS to unprove the Duluth Police Department's ability to identify patterns of criminal activity, to represent those patterns graphically, and to use the information to facilitate the management of departmental resources. As a result of this study, we recommend the implementation of a Geographic Information System. This recommendation is based on our findings which reveal that: (1) the Duluth Police Department's data capturing and analysis systems utilize outdated hardware and software that will soon be obsolete, (2) the current records management system is reasonably compatible with a geographically based management system, (3) the emergency management systems are structured in such a way so as to make the transition to a GIS oriented process manageable, and (4) GIS based procedures are being used by other agencies as efficient and effective means for managing crime prevention and crime resolution and for managing agency fiscal, material, and personnel resources. The present systems can be modified to a GIS, since they have the basic elements already in place. Both those systems associated with the Duluth Police Department and those connected with the 911 System can be used for developing a GIS that will provide for the needs of DPD and will provide a basis for use by other agencies dispensing emergency related services in the area.Item GIS Based Wetland Assessment Methodology for Urban Watershed Planning(1997) Snyder, Douglas J.Item GIS in Dakota County.
