Application of Remotely Sensed Image Data and Remote Sensing Technology to Map Suspended Sediment Information

By Pat Chavez

Pre-Proposal

Issue/Problem

Detecting and mapping suspended sediment concentrations and patterns are important to many different aspects of both coastal and in-land water environments. Currently, there is not an easy to use and inexpensive operational procedure to detect and map suspended sediment information on both a local and regional scale. Current operational suspended sediment mapping tools and procedures can be costly and time intensive. Existing automated suspended sediment measurement equipment often require extensive field maintenance due to the fact that the instrument package is in the water for prolong periods of time. For many applications and environments both remotely sensed images and spectral field radiometer data can be used to help with the mapping of surface suspended sediment concentrations and patterns.

Objective

To develop and refine procedures that are useful for detecting and mapping suspended sediment using both remotely sensed image and field spectral radiometer data. A procedure and equipment used for operational detection and mapping of suspended sediment must not only be easy to use, but portable and usable in different environments (e.g., both coastal and river waters). This project will investigate the use of both remotely sensed image and field spectral radiometer data for operational detection and mapping of suspended sediments in various environments, including coastal and in-land waters.

Approach

The large areal coverage of remotely sensed satellite and airborne images makes them useful for mapping and monitoring both relatively local and regional areas. The portability and compactness of field spectral radiometer instruments developed for the remote sensing community make them good candidates for in-situ use to get very local and high temporal resolution suspended sediment information without touching the water. A study is needed to take what has been done in a research mode mapping suspended sediment information using remote sensing and further develop and fine tune the procedures for more operational and wide spread use. Conditions and environments in which this type of a procedure would be useful, as well as limitations of these data, need to be identified.
