[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 Alameda Bridge, upstream Paseo Del Norte, Central Bridge, Isleta were attached at the [Data and References].
