| 355 | Water level on the screen : 63.4cm. The desired flux rqte was 80L/min, we used the 16mm diaphragm and measured a rate of 94.7L/min. |
| 356 | |
| 357 | Observations : The flow took 20s to reach the first corner, nothing crosses the shelf, a circulation is created on the shelf by water turning on the 1st or 2nd corner. |
| 358 | |
| 359 | After a while some part of the current started following the slope after the 2nd corner. |
| 360 | |
| 361 | |
| 362 | === Experiment EXP15 === |
| 363 | We wait for the water level to decrease (for about 2 hours) and reach 62.7cm on screen. |
| 364 | |
| 365 | The desired flow rate is 50L/min and with the diaphragm of 12.6mm we measured a flow rate of 52.2L/min. |
| 366 | |
| 367 | Observations : The flow reaches the first corner very quickly, then turned to the left and circulated on the shelf quite fast. Then a second branch started circulating inside the depression following the bathymetry. |
| 368 | |
| 369 | After that a third smaller branch started to follow the slope. |
| 370 | |
| 371 | Note : After this experiment, inertial oscillations appeard and the water started to move so we had to wait until further experiments. |
| 372 | |
| 373 | |
| 374 | === Experiment EXP16 === |
| 375 | When we started this experiment the inertial oscillations were reduced but not suppressed. |
| 376 | |
| 377 | The desired flow was 35L/min, with the diaphragm of 10mm we measured 36L/min. |
| 378 | |
| 379 | Observations : At the first corner a larg part of the flow turned left and went on the shelf, circulating in a larger vein than the previous experiment. |
| 380 | |
| 381 | Some water reaches the 2nd corner spliting in a major part entering the depression and a smaller and slower part flowing along the slope. |
| 382 | |
| 383 | There was no recirculation inside the depression, all the flow was evactued at the end of the depression bypassing the "land". |
| 384 | |
| 385 | |
| 386 | === Experiment EXP17 === |
| 387 | |
| 388 | At the beginning of the experiment there were almost no oscillations left. |
| 389 | |
| 390 | The desired flow was 20L/min, with a diaphragm of 8.2mm we measured 21.6 L/min. |
| 391 | |
| 392 | Observations : At the 1st corner the flow continued straight ahead. At the 2nd corner the flow splited in 2 branches of equal size, one following the slope and on entering the depression. |
| 393 | |
| 394 | There was a very clear a very clear and narrow jet following the bathymetry inside the depression, with a lot of meanders on its sides. |
| 395 | |
| 396 | After a while a branch detached from the slope current at the western corner of the depressionm entered the depression and recirculated joining the eastern side of the depression (drawing on the experiment paper). |
| 397 | |
| 398 | We wanted to keep the same setup and to inscrease the flow rate to 80L/min in order to have consistency but unfortunately we were running out of time. |
