Wetland Bathymetry and Mapping
Bathymetry is the measurement of underwater topography. In wetlands, development of bathymetric maps can have many applications, including determining water storage capacity and hydroperiod (depth and timing of flooding) of a wetland, assisting with wetland design and restoration and land use planning, and facilitating legal boundary determination. This chapter provides practical steps for mapping and modeling wadeable wetland bathymetry. By characterizing the bathymetry of wetlands, investigators can better understand key hydrologic, geomorphologic, and ecological processes of wetlands. Using standard survey equipment, investigators can plan and implement a relatively simple survey of wetlands. These data can be used to model and quantitatively analyze the surface area, volume, and bottom topography (bathymetry) of wetlands using standard geographic information system software.
