Features include two dimensional (2-D) overland flow, 1-D stream flow, 1-D infiltration, 2-D groundwater, and full coupling between the groundwater, shallow soils, streams, and overland flow. Sediment and constituent fate and transport are simulated in the shallow soils, overland flow plane, and in streams and channels. GSSHA can be used as an episodic or continuous model where soil surface moisture, groundwater levels, stream interactions, and constituent fate are continuously simulated. The fully coupled groundwater to surface-water interaction allows GSSHA to model basins in both arid and humid environments.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"has-text-align-center has-white-background-color has-background has-medium-font-size\">GSSHA Tutorial and Training Videos are now on <a href=\"https:\/\/www.youtube.com\/@GSSHATutorials\/videos\" target=\"_blank\" rel=\"noreferrer noopener\">YouTube<\/a><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.youtube.com\/@GSSHATutorials\/videos\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"900\" height=\"459\" src=\"https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/08\/gssha-tutorial-screenshot.jpg\" alt=\"\" class=\"wp-image-19803\" srcset=\"https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/08\/gssha-tutorial-screenshot.jpg 900w, https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/08\/gssha-tutorial-screenshot-300x153.jpg 300w, https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/08\/gssha-tutorial-screenshot-768x392.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/a><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"featured_media":18014,"template":"","tags":[],"class_list":["post-18021","tools","type-tools","status-publish","has-post-thumbnail","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model - Engineering With Nature<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/ewn.erdc.dren.mil\/tools\/gridded-surface-subsurface-hydrologic-analysis-gssha-model\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model - Engineering With Nature\" \/>\n<meta property=\"og:description\" content=\"Gridded Surface Subsurface Hydrologic Analysis (GSSHA) is a physics-based, distributed, hydrologic, sediment and constituent fate and transport model.
