CONCLUSIONS
-
A hydroecological design has been accomplished for the Arroyo Alamar.
The design used the U.S. Army Corps of Engineers' HEC-RAS model to determine design flow depths, mean velocities, Froude numbers, and freeboards
for a typical cross-section featuring a compound prismatic channel with left and right overbank side channels.
- Gabion systems are a compromise between riprap and concrete channels, and are applicable to the hydroecological rehabilitation of Arroyo Alamar.
- The ecology and flora of Arroyo Alamar has been described and documented.
- Vegetative and gabion-lined systems have been documented.
- Horizontal and vertical design alignments have been accomplished. The use of the streambed of Arroyo Alamar as
source of borrow materials (sand mining) has been examined.
-
The present conditions of Arroyo Alamar have been documented for use as baseline data on which to base future assessments of channel rehabilitation
and restoration.
- A website (http://proyectoalamar.org) has been developed to inform
interested persons and the public at-large about the project.
