WEBVTT 00:21.930 --> 00:24.250 Hey , my name is Madison Yawn . I am a 00:24.260 --> 00:26.482 research physical scientist here in the 00:26.482 --> 00:28.670 coastal and hydraulics lab . I'm also 00:28.680 --> 00:30.680 the project manager for the coastal 00:30.680 --> 00:32.791 hazard system and I'm going to give a 00:32.791 --> 00:36.360 brief overview of CHS today . In recent 00:36.369 --> 00:38.258 years , the need for reliable and 00:38.258 --> 00:40.147 readily available coastal hazards 00:40.147 --> 00:42.313 information has been highlighted by an 00:42.313 --> 00:44.439 overall increase in storminess and 00:44.450 --> 00:46.240 damage from recent storms like 00:46.250 --> 00:49.250 hurricane Katrina Harvey and Ian to 00:49.259 --> 00:51.330 support the mission areas of federal 00:51.340 --> 00:54.220 agencies including the U A developing 00:54.229 --> 00:56.118 accurate coastal hazard . Zeta is 00:56.118 --> 00:57.951 essential for supporting coastal 00:57.951 --> 01:00.299 resiliency and access to this type of 01:00.310 --> 01:02.366 information is made possible through 01:02.366 --> 01:04.638 the coastal hazard system . The coastal 01:04.649 --> 01:07.698 hazard system with the acronym CHS is a 01:07.708 --> 01:10.359 national scale multi-agency initiative 01:10.549 --> 01:12.549 that is intended for the accurate , 01:12.549 --> 01:14.771 efficient and consistent quantification 01:14.771 --> 01:16.768 of coastal hazards along our US 01:16.778 --> 01:18.518 coastlines and other strategic 01:18.528 --> 01:20.472 locations critical to our national 01:20.472 --> 01:23.910 security . CHS provides high resolution 01:23.919 --> 01:26.030 and high fidelity modeling of coastal 01:26.030 --> 01:28.470 storms and their associated hazards in 01:28.480 --> 01:30.980 a probabilistic context making this 01:30.989 --> 01:32.930 information highly beneficial for 01:32.940 --> 01:34.718 planning , engineering and risk 01:34.718 --> 01:37.300 assessment applications . The methods , 01:37.309 --> 01:39.199 data and tools that are contained 01:39.209 --> 01:41.265 within the coastal hazard system are 01:41.265 --> 01:43.449 provided consistently on a national 01:43.459 --> 01:45.730 scale and are extremely valuable as a 01:45.739 --> 01:47.961 resource for coastal engineering within 01:47.961 --> 01:51.779 the U A . With data sharing and 01:51.790 --> 01:54.089 accessibility in mind , CHS was 01:54.099 --> 01:55.877 initially developed to make the 01:55.877 --> 01:58.099 resulting data from large scale coastal 01:58.099 --> 02:00.510 hazard studies publicly available and 02:00.519 --> 02:03.440 easily accessible today . CHS is a 02:03.449 --> 02:05.616 multi component system that includes a 02:05.620 --> 02:08.005 data sharing platform , a state of the 02:08.014 --> 02:10.404 art probabilistic framework for hazard 02:10.414 --> 02:12.925 analysis and the storm sim suite of 02:12.934 --> 02:15.354 stochastic engineering tools . These 02:15.365 --> 02:17.755 components are included within CHS for 02:17.764 --> 02:20.104 the purpose of developing distributing 02:20.115 --> 02:22.393 and applying coastal storm hazard data . 02:22.820 --> 02:24.709 The coastal hazards data provided 02:24.709 --> 02:26.880 through CHS are regularly used to 02:26.889 --> 02:28.759 support a broad spectrum of 02:28.770 --> 02:31.020 applications which includes risk 02:31.029 --> 02:33.039 analysis , feasibility and coastal 02:33.050 --> 02:34.828 storm risk management studies , 02:34.839 --> 02:37.460 engineering design mapping and hazard 02:37.470 --> 02:39.919 predictions for decision making support 02:40.139 --> 02:42.600 for these applications . And more CHS 02:42.610 --> 02:45.110 allows for significant cost savings to 02:45.119 --> 02:47.720 the USA and other partners by making 02:47.729 --> 02:50.062 this data fully and publicly accessible . 02:51.160 --> 02:53.271 The primary source of data within the 02:53.271 --> 02:55.493 coastal hazard system is regional scale 02:55.493 --> 02:57.309 coastal hazard studies that are 02:57.320 --> 02:59.610 conducted by the USA and other federal 02:59.619 --> 03:02.339 agencies in these studies . Hundreds to 03:02.350 --> 03:04.520 thousands of synthetic and historical 03:04.529 --> 03:06.559 storm events are simulated under 03:06.570 --> 03:09.059 varying sea level conditions and these 03:09.070 --> 03:11.237 modeling results serve as is the input 03:11.237 --> 03:13.654 for the hazard analysis by making this 03:13.664 --> 03:16.554 data publicly accessible U A engineers 03:16.565 --> 03:18.343 can leverage these modeling and 03:18.343 --> 03:20.845 statistics results to define existing 03:20.854 --> 03:23.395 conditions for smaller project areas 03:23.535 --> 03:25.591 which reduces the amount of modeling 03:25.591 --> 03:27.479 and associated costs required for 03:27.479 --> 03:30.029 planning and feasibility studies . The 03:30.039 --> 03:32.570 CHS data has been leveraged in dozens 03:32.580 --> 03:34.802 of studies including coastal storm risk 03:34.802 --> 03:36.969 management and engineering with nature 03:36.969 --> 03:38.740 studies . Proving its value by 03:38.750 --> 03:40.806 supporting a variety of needs within 03:40.806 --> 03:44.199 the USA . The coastal hazard system 03:44.210 --> 03:46.266 website and web tool are the primary 03:46.266 --> 03:48.432 locations where the available modeling 03:48.432 --> 03:50.839 and statistics results can be accessed . 03:51.080 --> 03:53.559 The web tool is a map based interface 03:53.570 --> 03:55.440 which allows users to visualize 03:55.449 --> 03:57.710 thousands of point locations where data 03:57.720 --> 03:59.839 is available for a particular study 03:59.850 --> 04:02.389 region based on the user's location of 04:02.399 --> 04:04.440 interest . The data can be accessed 04:04.449 --> 04:06.560 from point locations shown on the map 04:06.809 --> 04:08.420 and users have the option of 04:08.420 --> 04:10.642 downloading the modeling and statistics 04:10.642 --> 04:14.029 data in an HDF five or CS V file format 04:14.559 --> 04:16.549 with data available for multiple 04:16.559 --> 04:18.839 coastal studies . The documentation of 04:18.850 --> 04:21.200 this information is a central part of 04:21.209 --> 04:23.940 CHS . The modeling and statistics 04:23.950 --> 04:27.059 results are natively stored as HDF five 04:27.070 --> 04:29.399 files which contain the associated 04:29.410 --> 04:31.410 metadata needed to make the files . 04:31.420 --> 04:34.480 Self describing this metadata is also 04:34.489 --> 04:36.850 included as separate read me files for 04:36.859 --> 04:39.081 any modeling or statistics results that 04:39.089 --> 04:41.489 are downloaded from the CHS web tool . 04:41.760 --> 04:44.290 Additionally , the CHS website offers a 04:44.299 --> 04:47.140 regularly updated user guide and quick 04:47.149 --> 04:49.440 start guide to help users navigate 04:49.450 --> 04:51.228 through the web tool and access 04:51.228 --> 04:52.209 available data . 04:56.760 --> 04:58.982 In addition , the coastal hazard system 04:58.982 --> 05:00.959 also includes a library where 05:00.970 --> 05:02.529 supplemental data files and 05:02.540 --> 05:05.079 publications associated with each study 05:05.089 --> 05:07.529 are stored for user access . This 05:07.540 --> 05:09.959 includes various KML files of storm 05:09.970 --> 05:12.100 tracks , storm parameter . Files 05:12.109 --> 05:14.529 uncertainty data and more . The coastal 05:14.540 --> 05:16.790 hazard system is a unique repository 05:16.799 --> 05:18.743 for coastal hazards data and is an 05:18.743 --> 05:20.688 extremely valuable resource to the 05:20.688 --> 05:21.688 coastal community 05:24.600 --> 05:27.980 dic discovering , developing and 05:27.989 --> 05:30.100 delivering new ways to make the world 05:30.100 --> 05:32.100 safer and better every day .
