projects > flow velocity
and water level transects
The data collection effort will use the newest state-of-the-art acoustic
velocity and global positioning systems to obtain the location, velocity, and
direction of flow of water moving through the National Park. Extremely low
velocities (1 mm/s) can be measured with this equipment.
The primary product of this effort will be data to be used by other parts of
the overall study. Databases of the processed data will be created for
inclusion in the ongoing modeling efforts, as well as possible use in future
projects. The technology and procedure with sample results will be published
in a fact sheet format near the end of the project.
The data collection effort will be accomplished in three phases, low, medium, and high water conditions. The exact
timing will be determined by water levels and the needs of the two primary modeling projects. Continuous collection points will
be established in Taylor Slough where depth and velocity observances will be recorded on a set time interval during each of the
intensive data collection periods. Additional mobile measurement will be made at several locations along Transects for
comparisons with the fixed points in Taylor Slough and serve as input points for the models. The low water data collection
period will be in April, the medium water in August and the high water in July of each year. Data from each run will be available
in the data base two months after collection. The data will be stored in the data base in the format of:
