Sensor response to overtopping and failure
The next slide shows sensor responses to the rise in reservoir level, overtopping and dam failure. Sensor 19S is missing because the pressure sensor was moved to the 2N position. 27S shows the reservoir level rise, with 15S and 9S responding within the hour. The 27S level slowly drops as the headcut pushes the Bernoulli drop back towards the sensor. The reservoir level show the effects of breach at about 1345 hours. An extension of the breach washes out 9S at about 1400 hr, after which it is removed. At about 1425 hr, the channel supply to the reservoir is cut off and the remaining water begins to drop more quickly. At 1500 hrs, the experiment is terminated.
