WEBVTT 00:00.200 --> 00:01.922 When floods threaten lives and 00:01.922 --> 00:04.210 infrastructure , decisions must be made 00:04.210 --> 00:06.050 quickly . The US Army Corps of 00:06.050 --> 00:08.640 Engineers Hydrologic Engineering Center , 00:08.930 --> 00:11.930 or provides the modeling tools , 00:12.170 --> 00:15.310 methods , and expertise used nationwide 00:15.449 --> 00:18.209 for hydrologic and hydraulic analysis . 00:18.409 --> 00:20.631 It's important to have the state of the 00:20.631 --> 00:22.853 art tool to be able to quickly do flood 00:22.853 --> 00:25.469 risk analysis to come up with . 00:26.139 --> 00:29.459 Solutions quickly and accurately . It 00:29.459 --> 00:31.959 saves lives . Central to that support 00:31.959 --> 00:35.459 is HEC RAS , a powerful hydraulic 00:35.459 --> 00:37.900 modeling software that helps teams 00:37.900 --> 00:40.011 understand where water will go , when 00:40.011 --> 00:42.067 it will get there , how deep it will 00:42.067 --> 00:44.400 get , and what measures can reduce risk . 00:44.540 --> 00:46.759 HEC RAS is the primary hydraulic 00:46.759 --> 00:48.981 engineering tool used by the Army Corps 00:48.981 --> 00:50.926 of Engineers . It supports . Civil 00:50.926 --> 00:53.959 works missions with flood risk 00:53.959 --> 00:57.080 management , emergency response , dam 00:57.080 --> 00:59.229 and levee safety studies , as well as 00:59.229 --> 01:01.396 navigation and environmental studies . 01:02.500 --> 01:04.400 RAS stands for the Hydrologic 01:04.400 --> 01:06.839 Engineering Center's River Analysis 01:06.839 --> 01:09.760 System . It's a powerful software model 01:09.760 --> 01:11.760 that simulates the physics of water 01:11.760 --> 01:13.927 flowing through river channels and the 01:13.927 --> 01:17.010 flood plain . We have federal partners 01:17.010 --> 01:19.410 and local partners that utilize RAS as 01:19.410 --> 01:21.577 well as consultants , and it's used in 01:21.577 --> 01:24.250 200 countries around the world . We 01:24.250 --> 01:28.150 have over 170,000 downloads each year . 01:28.769 --> 01:31.650 We've seen 5.5 million views of our 01:31.650 --> 01:34.169 documentation pages and over a million 01:34.169 --> 01:36.391 views on our YouTube training content . 01:36.535 --> 01:39.144 With HEC RAS , engineers can map and 01:39.144 --> 01:42.065 analyze floodplains to predict flooding , 01:42.375 --> 01:44.955 evaluate bridge and culvert impacts , 01:45.334 --> 01:47.205 model stormwater systems and its 01:47.205 --> 01:49.815 interaction with surface water , assess 01:49.815 --> 01:52.294 public risk if levees or dams designed 01:52.294 --> 01:55.455 to protect them over top , and analyze 01:55.455 --> 01:58.699 sediment and water quality . While HEC 01:58.699 --> 02:00.519 RAS remains the cornerstone of 02:00.519 --> 02:03.089 hydraulic engineering software , its 02:03.089 --> 02:05.290 foundational code was developed 30 02:05.290 --> 02:08.610 years ago . I'm one of the only ones 02:08.610 --> 02:11.130 who learned RAS in school , you know , 02:11.520 --> 02:13.576 some of the other guys on the team , 02:13.576 --> 02:15.687 they've , they've been developing RAS 02:15.687 --> 02:17.853 from the beginning , but I learned RAS 02:17.853 --> 02:20.020 at the University of Wisconsin as a 20 02:20.020 --> 02:22.187 year old and have used it ever since , 02:22.187 --> 02:24.520 uh , and it's a delightful program . Uh , 02:24.520 --> 02:27.000 but it feels like I learned it 25 years 02:27.000 --> 02:29.119 ago . To be able to continue to 02:29.119 --> 02:31.286 innovate , the team decided to rewrite 02:31.286 --> 02:33.220 the software so they can leverage 02:33.220 --> 02:35.779 modern software programming technology 02:35.779 --> 02:38.520 and architecture . So we used to talk 02:38.520 --> 02:41.789 about like how you visualized rivers in 02:41.789 --> 02:43.880 Raz as the stick figure . You can 02:43.880 --> 02:46.360 imagine it's a series of sticks tied 02:46.360 --> 02:48.582 together by a string . It's literally a 02:48.582 --> 02:50.471 stick figure of a river . You can 02:50.471 --> 02:53.136 actually kind of drape what we call a 02:53.136 --> 02:55.895 mesh , which is a realization of the 02:55.895 --> 02:58.656 world over the actual map , kind of 02:58.656 --> 03:00.735 like you would in a video game . You 03:00.735 --> 03:02.902 can see things that are flooding . You 03:02.902 --> 03:05.636 can understand where obstacles would be , 03:06.016 --> 03:08.238 and so it just looks much more like the 03:08.238 --> 03:10.405 real world . We're going to spend more 03:10.405 --> 03:12.516 time with the analysis because we are 03:12.516 --> 03:14.238 going to be spending less time 03:14.238 --> 03:16.376 acquiring data and ingesting it into 03:16.376 --> 03:19.552 the . RS 2025 , we do want to make drag 03:19.552 --> 03:21.663 and drop friendly , resize friendly . 03:21.663 --> 03:23.441 People are working on different 03:23.441 --> 03:25.608 monitors now . People are on laptops , 03:25.608 --> 03:27.830 on huge monitors , on tablets even . So 03:27.830 --> 03:29.941 since people have a variety of screen 03:29.941 --> 03:32.163 sizes and shapes , we want to make sure 03:32.163 --> 03:34.385 that the software kind of respects that 03:34.385 --> 03:36.608 and reacts to that . Providing industry 03:36.608 --> 03:38.719 standard software is only part of the 03:38.719 --> 03:40.830 RAS team's mission . They also ensure 03:40.830 --> 03:42.941 users have the knowledge and guidance 03:42.941 --> 03:45.108 to apply the . To correctly . So we're 03:45.108 --> 03:47.330 doing this road show . We're taking the 03:47.330 --> 03:49.552 software on the road to the 9 divisions 03:49.552 --> 03:51.608 in order to train the people who are 03:51.608 --> 03:53.830 going to use it and to be honest , when 03:53.830 --> 03:55.830 they come in , they're a little bit 03:55.830 --> 03:57.719 hesitant . They're coming in to a 03:57.719 --> 03:59.830 training where we're going to replace 03:59.830 --> 04:01.774 the piece of software they've used 04:01.774 --> 04:03.830 their whole career , sometimes every 04:03.830 --> 04:05.885 day . By the middle of the first day 04:05.885 --> 04:08.108 they're intrigued . They're like , OK , 04:08.108 --> 04:10.304 this is better . it's . Faster . I'm 04:10.304 --> 04:13.623 moving around better . Maybe by the 04:13.623 --> 04:15.790 middle of the 2nd day they're all in . 04:15.790 --> 04:17.956 They realize that it's not only a more 04:17.956 --> 04:20.123 efficient piece of software , but it's 04:20.123 --> 04:22.290 more powerful . It's not only going to 04:22.290 --> 04:24.401 make them faster , it's going to make 04:24.401 --> 04:26.567 them better at their job and uniformly 04:26.567 --> 04:28.664 across the districts by the time we 04:28.664 --> 04:30.664 leave , by the end of the 3rd day , 04:30.664 --> 04:32.775 there's excitement to implement . The 04:32.775 --> 04:35.743 tools AGC 2025 supplies are not just 04:35.743 --> 04:37.820 for the US . Army Corps of Engineers 04:38.279 --> 04:40.559 HEC makes its software publicly 04:40.559 --> 04:42.720 available , empowering a global 04:42.720 --> 04:45.399 community of engineers , planners , and 04:45.399 --> 04:47.589 researchers to protect communities , 04:47.720 --> 04:50.040 restore habitats , and manage water 04:50.040 --> 04:52.119 resources effectively . Some of our 04:52.119 --> 04:55.079 partners have referred to RAS 2025 as 04:55.079 --> 04:58.399 their wishbone because with one model 04:58.399 --> 05:01.119 you'll be able to model a large 05:01.119 --> 05:04.579 watershed scale model . But then also 05:04.579 --> 05:06.899 further refine it for a detailed 05:06.899 --> 05:10.179 localized study , so this will reduce a 05:10.179 --> 05:13.739 lot of rework and duplicate models with 05:13.739 --> 05:17.220 tools like HEC RS 2025 , we are better 05:17.220 --> 05:18.942 equipped than ever to meet the 05:18.942 --> 05:21.164 challenge of understanding our rivers . 05:21.220 --> 05:24.209 Working with a group of individuals , 05:24.220 --> 05:27.260 all with different skill sets really 05:27.260 --> 05:29.640 brings together the best in everybody . 05:30.250 --> 05:32.459 And I think that's really reflected in 05:32.459 --> 05:35.059 the HCRAS software . This piece of 05:35.059 --> 05:37.500 software is trusted throughout the 05:37.500 --> 05:40.790 world . Um , and has been used 05:41.230 --> 05:45.140 to design and implement . Thousands 05:45.140 --> 05:47.500 of projects .
