- Integrate the results of FLO-2D model (a
two-dimensional river flow and floodplain inundation model)
into GIS-based mapping product.
- Presentation of inundated area, depth of
water, etc. as smooth contour line in GIS layer.
FLO-2D,
a two-dimensional flow model utilized in the Middle Rio Grande
for river restoration design and floodplain delineation, will
be used to distinguish the 5,400 cubic feet per second (cfs),
7,000 cfs, 8,700 cfs, and 10,000 cfs on the reach of the Rio
Grande from San Acacia Diversion Dam to headwaters of Elephant
Butte Reservoir. Floodplain delineation maps showing model
results including inundated areas and depth of water will
be produced. This project will allow management of the output
data to display the necessary information in a much clearer
fashion. Geographic Information System (GIS) software will
be used with FLO-2D model output to produce the final maps,
making the output information accessible to multiple users.
Maps produced using FLO-2D model results will
be reviewed by private landowners interested in determining
where active floodplains would be in relation to their lands
in Socorro County. This information may be used to identify
properties eligible for conservation easements. This is an
important aspect of the information gathering stage of floodplain
management in the area. Additionally, this information will
be used in relation to restoration of native habitats along
the Rio Grande in the Socorro Reach, on both public and private
lands.
GIS software
will be used with digital output produced by the FLO-2D model
to produce user-friendly maps that will be presented to landowners
and others interested in river restoration and floodplain
delineation. The final product will be maps showing inundated
areas and depth of water resulting from model runs simulating
a 5,400 cubic feet per second (cfs), 7,000 cfs, 8,700 cfs,
and 10,000 cfs on the reach of the Rio Grande from San Acacia
to San Marcial.
This
project will serve as a tool to present data in a user-friendly
format for review by private landowners and others interested
in river restoration and floodplain delineation. Data management
techniques for final map presentation will be available for
others working on the Rio Grande with FLO-2D.
