[Task 3] Piano-Like Gate Opening Configuration March
9
Task 3, piano-like gate
opening configuration was tested from March 6-7. The configuration procedure result of time
series gate openings observed by Quitin Cox was attached at the [Data and References] section.
Gate #24 was not included in
the configuration because of the west bank erosion. Figures 1 and 2 show the erosion induced by gate
#23 opening on 6-Mar.
Gate #1, 2, and 19 were
opened on 9-Mar (figures 3 and 4). Fish
passage surface velocity was measured 2.7 ft/s.
By the way, the USGS water
surface level during the piano-like configuration shows interesting changes
maybe because of the gate operation backwater. Five hydrographs: Below Cochiti Dam, San Felipe,
upstream
