Humphreys and Lieutenant H.L. Abbot of the U.S. Army Corps of Topographical Engineers. Drawn by Charles Mahon, the map depicts the Mississippi River from Cape Girardeau to the delta, documenting the extensive alluvial region with scientific precision including soundings shown in fathoms. Created to accompany Humphreys and Abbot's groundbreaking report on the physics and hydraulics of the Mississippi River, this cartographic achievement represented the culmination of the Mississippi Delta Survey authorized by Congress in 1850 with a $50,000 appropriation. The map served as an essential component of what would become known as the most influential hydraulic engineering study of the nineteenth century, fundamentally shaping American understanding of river systems and flood control strategies.\u003cbr\u003e\u003cbr\u003eThe Humphreys-Abbot report emerged during a transformative period when southern communities desperately sought federal assistance against catastrophic flooding that periodically devastated New Orleans and lower Mississippi settlements. Their comprehensive survey revolutionized hydraulic engineering theory, establishing the \"levees only\" doctrine that would dominate American river management for sixty years. Published as the Civil War commenced, this scientific document transcended regional conflicts, earning international respect from engineers worldwide while profoundly influencing the Corps of Engineers' evolution and America's approach to water resource development through World War II and beyond.\u003cbr\u003e\u003cbr\u003eThis exceptional map serves as a window into America's pioneering efforts to understand and control its greatest river system. The detailed documentation of the Mississippi's alluvial region represents a testament to antebellum scientific achievement, making it an extraordinary addition to any collection celebrating this unique piece of American engineering history.\u003c\/p\u003e","brand":"Historic Prints","offers":[{"title":"18x24 Inch","offer_id":46320326443197,"sku":"ENMAP0751_1824H","price":59.99,"currency_code":"USD","in_stock":true},{"title":"24x36 Inch","offer_id":46320326475965,"sku":"ENMAP0751_2436H","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0504\/5459\/3725\/files\/82622e61-bfc7-5dee-9547-3508d75d699f.jpg?v=1768785633","url":"https:\/\/historicprints.com\/products\/1861-mississippi-river-delta-alluvial-region-map","provider":"Historic Prints","version":"1.0","type":"link"}
