摘要

A methodology that utilizes georeferenced imagery to analyze spatial fluid mud flux measurements pre-, during-, and post-dredging is described. The spatial analysis technique utilizes novel passive sonde sampling techniques and above surface imagery in ArcGIS to geometrically represent fluid mud flux over a specific area of the dredging project waterway. Transect data obtained from the Indian River Lagoon (IRL), south of Sebastian Inlet, Florida is used to mathematically calculate combined fluid mud and flocculation transport in the North, South, East, West, settling (depositional), and upwelling (resuspension) directions across the navigable marine channel at four transects. Satellite imagery is transferred into raster images using ten point image to image georeferencing technique and a 3rd order image transformation providing a root mean square error of < 0.1 m. A kriging technique coupled with contouring was utilized to give a spatial representation of the point sampling data between sampling stations. Digitization of the water area is essential in order to calculate the flux over the surface area of the nearby estuary. The advantages of these techniques are the estimation of fluid mud movement over an estuarine region given sonde data during the dredging of waterways in coastal areas. The techniques are transferrable to other water bodies.
