WEBVTT 00:21.459 --> 00:24.069 Hi , I'm Pierce Chen . I'm the Chief of 00:24.079 --> 00:26.579 the Hydrologic Systems Branch in the 00:26.590 --> 00:29.139 coastal and hydraulics Laboratory of 00:29.149 --> 00:31.850 the US Army Engineer Research and 00:31.860 --> 00:33.990 Development Center today . My 00:34.000 --> 00:37.509 presentation is on G MS Groundwater 00:37.520 --> 00:41.369 modeling System . What 00:41.380 --> 00:44.880 is a good description of G MS G MS is 00:44.889 --> 00:46.778 the most advanced software system 00:46.778 --> 00:48.833 available for performing groundwater 00:48.833 --> 00:50.778 simulations in a three dimensional 00:50.778 --> 00:53.799 environment . With G MS . One can 00:53.810 --> 00:56.229 create 3D models with a speed and 00:56.240 --> 00:58.360 simplicity for groundwater and 00:58.369 --> 01:01.659 subsurface simulations . G MS supports 01:01.669 --> 01:03.939 multiple computational models that 01:03.950 --> 01:06.980 include the mud flow , mud flow us G 01:06.989 --> 01:10.930 mud flow NWT mud flow LGR mud 01:10.989 --> 01:14.580 path MT 3D MSP HT three 01:14.589 --> 01:17.970 DC W A RT 3d SI 01:18.029 --> 01:21.019 3d mud A E MC , two 01:21.029 --> 01:24.830 DF water fe flow and top 01:24.839 --> 01:27.669 two G MS also supports multiple 01:27.680 --> 01:29.989 computational utilities that include 01:30.000 --> 01:33.430 past zone budget , sync 01:33.440 --> 01:37.440 solver and T PRO G MS can interact 01:37.449 --> 01:41.120 with the models into 3d optimize open 01:41.129 --> 01:43.360 geographics for improved hardware 01:43.370 --> 01:46.379 rendering , create photorealistic 01:46.389 --> 01:49.589 renderings , generate animations for 01:49.599 --> 01:53.480 powerpoint or web presentations , drap 01:53.489 --> 01:55.980 images over the model and control the 01:55.989 --> 01:59.160 opacity and at the north arrows , 02:00.099 --> 02:03.650 scale bars , reference images , company 02:03.660 --> 02:07.190 logos , etc where and when should G MS 02:07.199 --> 02:10.850 be applied G MS can be applied 02:10.860 --> 02:13.139 to any groundwater systems that are 02:13.149 --> 02:15.360 modeled with the computational models 02:15.369 --> 02:18.899 that G MS supports G MS creates a 02:18.910 --> 02:21.429 realistic model of a groundwater system 02:21.479 --> 02:24.380 within active or abandoned mine areas 02:24.389 --> 02:26.929 and simulates mining and post mining 02:26.940 --> 02:30.199 effects such as dewatering and draw 02:30.250 --> 02:33.440 down aquifer recovery and mine poor 02:33.449 --> 02:36.350 development . The program supports 02:36.360 --> 02:39.029 automatic models calibration and has 02:39.039 --> 02:41.910 robust capability for the graphical 02:41.919 --> 02:44.869 output of a post processing result . 02:45.679 --> 02:49.470 G MS incorporates tins solids boho data 02:49.479 --> 02:52.479 two D and 3D GEOS statistics and both 02:52.490 --> 02:54.710 finite element and finite difference 02:54.720 --> 02:57.669 models in two D and 3D . In your mind 02:57.679 --> 03:00.710 analysis , G MS analyze 03:00.880 --> 03:04.779 flow through earth names and levies . G 03:04.789 --> 03:07.690 MS simulates the flow in confined or 03:07.699 --> 03:10.610 unconfined profile models or for 03:10.619 --> 03:14.270 confined aerial models . For unconfined 03:14.279 --> 03:16.929 models . Flow can be modeled in both 03:16.940 --> 03:19.970 the saturated and unsaturated zones . 03:20.000 --> 03:22.580 Solutions can be displayed using plots 03:22.589 --> 03:25.529 of flow vectors and head contours . 03:26.679 --> 03:29.419 G MS generates a complete flow net with 03:29.429 --> 03:31.910 equal potential lines and flow lines to 03:31.919 --> 03:34.369 analyze groundwater flow impacts . Due 03:34.380 --> 03:37.979 to my activity G MS models , the 03:37.990 --> 03:41.449 movement of contaminant plumes G MS 03:41.460 --> 03:43.889 generates animations to analyze and 03:43.899 --> 03:46.350 predict the fate of a contamination 03:46.360 --> 03:48.929 plume or my discharge over time 03:51.149 --> 03:53.639 where and when has G MS already been 03:53.649 --> 03:57.039 applied since G MS version 1.0 was 03:57.050 --> 04:00.809 released in December 1994 . G 04:00.820 --> 04:02.960 MS has been utilized to develop a 04:02.970 --> 04:05.559 groundwater models by engineers and 04:05.570 --> 04:08.210 researchers from government agencies , 04:08.220 --> 04:10.889 private sectors and academia for 04:10.899 --> 04:13.550 various purposes including water 04:13.559 --> 04:16.269 management , environmental remediation , 04:16.279 --> 04:19.239 et cetera . The latest G MS version is 04:19.250 --> 04:22.220 version 10.7 which was released in 04:22.230 --> 04:25.910 November 2022 . The information for G 04:25.920 --> 04:29.630 MS version 10.7 can be found in the G 04:29.640 --> 04:33.529 MS wiki . What is the broad spectrum 04:33.540 --> 04:36.829 impact of G MS ? Groundwater is of 04:36.839 --> 04:38.730 fundamental importance in water 04:38.739 --> 04:41.510 resource planning . Ground water models 04:41.519 --> 04:44.119 can be used to estimate the flow and 04:44.160 --> 04:46.390 aquiver characteristics for which 04:46.399 --> 04:48.621 direct measurements are not available . 04:49.260 --> 04:51.119 They can be used to simulate the 04:51.130 --> 04:53.309 response of the aquifer under 04:53.320 --> 04:55.890 hypothetical conditions . They can be 04:55.899 --> 04:58.339 used to identify sensitive regions 04:58.690 --> 05:01.059 where additional hydrologic information 05:01.070 --> 05:03.670 could improve understanding . They can 05:03.679 --> 05:06.799 be used to forecast expected artificial 05:06.809 --> 05:09.760 or natural changes in the system . Some 05:09.769 --> 05:12.200 models also carry a high degree of 05:12.209 --> 05:15.470 certainty . Groundwater models can be 05:15.480 --> 05:18.000 used to analyze the various assumptions 05:18.010 --> 05:20.440 with groundwater . They can be used to 05:20.450 --> 05:22.061 understand the ideology of a 05:22.061 --> 05:24.350 groundwater flow related to several 05:24.359 --> 05:27.839 general or specific problems . They can 05:27.850 --> 05:29.850 be used to regulate the groundwater 05:29.850 --> 05:32.239 balance in terms of water quantity . 05:32.679 --> 05:34.846 They can be used to help to know about 05:34.850 --> 05:37.140 the quantitative features of the 05:37.149 --> 05:40.709 unsaturated zone . Groundwater model 05:40.720 --> 05:43.109 can be used to simulate water flow and 05:43.119 --> 05:45.250 chemical migration in the situated 05:45.260 --> 05:47.510 regions including river groundwater 05:47.519 --> 05:50.750 relations . They can be used to assess 05:50.910 --> 05:53.630 the impact of the change in groundwater 05:53.640 --> 05:56.440 management on the environment . They 05:56.450 --> 05:58.450 can be used to set up monitoring 05:58.459 --> 06:01.730 networks and they can be used to set up 06:01.739 --> 06:05.040 groundwater protection zones . How can 06:05.049 --> 06:07.829 users get G MS ? Is it access 06:07.839 --> 06:10.779 restricted ? The US . Army Engineer 06:10.790 --> 06:13.059 Research and Development Center had the 06:13.070 --> 06:16.640 30 Flex licenses for G MS version 10.5 06:16.649 --> 06:20.440 or newer for us to use to maximize the 06:20.450 --> 06:23.299 availability of this G MS flex license 06:23.519 --> 06:26.959 to us users . 25 of them are available 06:26.970 --> 06:29.709 for checkout for 30 day time periods . 06:30.440 --> 06:32.440 If a user still needs the license . 06:32.440 --> 06:35.019 Beyond that time , the checkout can be 06:35.029 --> 06:38.609 renewed repeatedly . If there are more 06:38.619 --> 06:40.670 users , then there are available 06:40.679 --> 06:43.640 licenses , then priority use will have 06:43.649 --> 06:47.109 to be determined to request a GM SS 06:47.119 --> 06:49.950 Flex license .
