WETLAND MANAGEMENT AND MUNICIPAL PLANNING - Resource Inventory, Information Management and Water Quality Benefits
Direct and indirect impacts on existing wetlands potentially threaten this resource. There is a need for more information about the nature and extent of wetland resources and potential impacts of human activities on wetland systems. This information can then be incorporated into integrated water- and land-use planning efforts at the municipal level. This paper presents several techniques for examining historical wetland losses, performing wetland inventories and identifying watershed influence areas. Database management was facilitated with a geographic information system (GIS). The GIS was used to produce maps and handle inventory information. Preliminary wetland soil and water quality data were collected and found to be highly variable. Results of the water quality analyses, however, indicated that substantial pollutant removal occurred in some wetlands. Case study results are presented for Vadsbäcken, a riverine wetland in Norrköping’s kommun.
