Abstract
Time Series Analysis of Wetland Mitigation Sites Using ArcGIS Spatial Analyst
Track: Water Resources
Author(s): Kevin McMaster
Land development often necessitates draining and filling natural wetlands. However, negative environmental impacts are mitigated by construction of new wetlands elsewhere in the same watershed. This paper presents the integrated use of fieldwork, GIS, and time series analysis in determining which areas were successfully converted into wetlands for a case study project. Using an array of 49 monitoring wells, 86 sampling dates, and 1,200 spot height measurements, all areas that successfully met wetland criteria were identified. A subsequent interactive computer animation helped researchers identify the links between precipitation, temperature, and variable wetland boundaries.
