WEBVTT 00:00.280 --> 00:02.169 My name is Megan Munrove . I'm an 00:02.169 --> 00:04.169 associate professor at Oregon State 00:04.169 --> 00:06.391 University in coastal engineering , and 00:06.391 --> 00:08.224 out here we're looking at , uh , 00:08.224 --> 00:10.447 engineered composite beaches or dynamic 00:10.447 --> 00:12.613 revetments . So a composite beach is a 00:12.613 --> 00:14.720 natural beach where there's a sandy 00:14.720 --> 00:17.280 foreshore and a cobble backshore . They 00:17.280 --> 00:20.329 occur a lot in northern latitudes , but 00:20.600 --> 00:22.767 a lot in the Pacific Northwest , which 00:22.767 --> 00:24.878 is where we're from , so we're trying 00:25.040 --> 00:27.739 to test some natural nature based 00:27.739 --> 00:30.631 features , uh , and . Their design here 00:30.631 --> 00:32.881 in the the lab so that we can provide 00:32.881 --> 00:35.441 guidance for engineers to construct 00:35.441 --> 00:37.552 these features and design them in the 00:37.552 --> 00:39.701 fields . We hope the outcome is to 00:39.701 --> 00:42.390 provide more resources to engineers out 00:42.390 --> 00:44.680 there who are trying to design nature 00:44.680 --> 00:47.030 based solutions for coastal protection . 00:47.280 --> 00:49.881 There's really not much literature . 00:49.960 --> 00:52.160 There's some reports and some folks 00:52.160 --> 00:54.800 that have taken tools from other areas 00:54.800 --> 00:57.561 and try to implement them , so we are . 00:57.762 --> 01:00.922 Hoping to provide design guidance to 01:00.922 --> 01:03.652 engineers for designing dynamic reins 01:03.652 --> 01:05.763 in the field . The only other testing 01:05.763 --> 01:07.596 that's been done for seeing what 01:07.596 --> 01:09.708 volumes might work , that testing was 01:09.708 --> 01:11.930 done without sand , and what we've seen 01:11.930 --> 01:14.041 so far is that sand had kind of a big 01:14.041 --> 01:16.263 impact . So hopefully this testing is a 01:16.263 --> 01:18.152 little bit more realistic for the 01:18.152 --> 01:20.263 conditions that we usually see on the 01:20.263 --> 01:22.263 open coast and can give engineers a 01:22.263 --> 01:24.096 better ballpark of what kinds of 01:24.096 --> 01:26.096 volumes they should be using . It's 01:26.096 --> 01:28.263 really cool it it . We've been in here 01:28.263 --> 01:30.430 for a long time . I'm pretty tired and 01:30.430 --> 01:32.596 it's really nice to feel like the work 01:32.596 --> 01:34.485 that we're doing has a meaningful 01:34.485 --> 01:36.541 impact . At the same time , I'm also 01:36.541 --> 01:36.163 not surprised . Like we've known that 01:36.163 --> 01:39.002 this is a big kind of hole in our 01:39.002 --> 01:41.169 understanding for a long time . People 01:41.169 --> 01:43.335 have been building dynamic remnants on 01:43.335 --> 01:45.613 the Oregon coast since the early 2000s , 01:45.613 --> 01:47.669 and we just keep learning off of the 01:47.669 --> 01:49.613 previous projects . And because of 01:49.613 --> 01:51.722 limitations on hard structures and 01:51.722 --> 01:53.389 places that are continuing to 01:53.389 --> 01:55.555 experience coastal erosion , there's a 01:55.555 --> 01:57.389 Ton of demand for these kinds of 01:57.389 --> 01:59.333 structures . And so it's been very 01:59.333 --> 02:01.963 clear to us for a while that like more 02:01.963 --> 02:03.907 information is absolutely needed . 02:03.907 --> 02:05.907 We're looking at a lot of different 02:05.907 --> 02:07.963 questions . This flume in particular 02:07.963 --> 02:10.130 has been a good size because it allows 02:10.130 --> 02:12.185 us to work through lots of different 02:12.185 --> 02:12.044 permutations , lots of different 02:12.044 --> 02:14.444 configurations of our experiment , so 02:14.444 --> 02:16.555 we can answer , hopefully answer lots 02:16.555 --> 02:18.722 of different questions . I'm trying to 02:18.722 --> 02:21.000 find out one small part of that puzzle , 02:21.000 --> 02:23.203 whether the the cross shore sorting is 02:23.203 --> 02:24.814 easy to predict . To give in 02:24.814 --> 02:27.255 hydrodynamics and profile geometry . 02:27.365 --> 02:29.421 I'm hopeful because you can see it , 02:29.421 --> 02:31.587 you know , we've sat out here watching 02:31.587 --> 02:33.532 waves for hours and you can see it 02:33.532 --> 02:33.404 happening in front of your eyes . It's 02:33.404 --> 02:35.460 really interesting , especially when 02:35.460 --> 02:37.571 there's a really large wave that hits 02:37.571 --> 02:39.682 the front and the face of the berm as 02:39.682 --> 02:41.904 the wave pulls back the back rush , you 02:41.904 --> 02:44.126 can see this exfiltration of rocks come 02:44.126 --> 02:46.348 down the berm , be transported offshore 02:46.348 --> 02:48.682 only to be pushed back by the next wave , 02:48.682 --> 02:48.205 but you see these , these mechanisms in 02:48.205 --> 02:50.149 play , and it's , it's been really 02:50.149 --> 02:52.316 interesting . This is a really awesome 02:52.316 --> 02:54.372 lab . everybody's been . Super super 02:54.372 --> 02:56.594 nice , super welcoming super helpful we 02:56.594 --> 02:58.594 definitely could not have done this 02:58.594 --> 03:00.816 experiment without any of them and it's 03:00.816 --> 03:02.927 been really cool to get to meet other 03:02.927 --> 03:05.038 people from Erdic as well to see what 03:05.038 --> 03:06.945 it's like to be at an engineering 03:06.945 --> 03:09.005 research facility because I've never 03:09.005 --> 03:11.172 really gotten to see that before . And 03:11.172 --> 03:13.445 so talking to people about their jobs 03:13.445 --> 03:15.556 and the projects that they're working 03:15.556 --> 03:17.778 on and their friends' projects and what 03:17.778 --> 03:19.834 they're working on , uh , gives me a 03:19.834 --> 03:21.889 better picture of what's going on at 03:21.889 --> 03:24.056 the whole of Edict and . That's really 03:24.056 --> 03:26.001 cool . Having partners like Oregon 03:26.001 --> 03:28.223 State University is a real , you know , 03:28.223 --> 03:30.334 I'm something I'm really grateful for 03:30.334 --> 03:32.445 and a great opportunity for Erdic and 03:32.445 --> 03:34.389 so to partner with them is only uh 03:34.389 --> 03:36.112 aiding Erdic and expanding our 03:36.112 --> 03:38.389 capabilities and so as we move forward , 03:38.389 --> 03:40.056 you know , we look forward to 03:40.056 --> 03:42.223 continuing this collaboration but also 03:42.223 --> 03:44.389 what comes out of this research , what 03:44.389 --> 03:46.556 comes out of this effort , what we can 03:46.556 --> 03:48.778 learn and hopefully you know transition 03:48.778 --> 03:48.246 to the field transition to the 03:48.246 --> 03:51.100 districts so they can you know . Design 03:51.100 --> 03:53.539 better designed faster , and , and 03:53.539 --> 03:55.261 improve uh the function of our 03:55.261 --> 03:57.428 coastlines for , you know , everyone , 03:57.428 --> 03:59.539 you know , Artic , you know , we have 03:59.539 --> 04:01.539 one of probably probably one of the 04:01.539 --> 04:01.339 largest groups of coastal engineers , 04:01.460 --> 04:03.820 coastal scientists in the world , but 04:03.820 --> 04:05.709 at the same time there's a lot of 04:05.709 --> 04:07.899 expertise out there , uh , that's 04:07.899 --> 04:09.843 always growing . The science , the 04:09.843 --> 04:12.066 field is always growing and so you know 04:12.066 --> 04:14.177 you don't wanna operate in a vacuum , 04:14.177 --> 04:16.010 you don't wanna . uh in a closed 04:16.010 --> 04:18.232 environment so it's always important to 04:18.232 --> 04:20.455 always have your hands out there uh and 04:20.455 --> 04:22.510 interacting , learning from others , 04:22.510 --> 04:24.732 they're learning from you and that just 04:24.732 --> 04:26.899 advances everyone much quicker so that 04:26.899 --> 04:29.066 collaboration is really what grows and 04:29.066 --> 04:28.929 it's a huge part of what we call the 04:28.929 --> 04:29.570 power of learning .
