This book was released on 1988 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landsat images were used to map ice distributions along a 72-mile section of the Allegheny River, and the 129-mile-long Monongahela River. River reaches with grey ice and white ice were mapped based on images tones using conventional photointerpretation techniques. Portions of a river that appeared black were mapped as ice free, although thin, transparent ice could also appear black. Grey tones were produced by ice that varied from patches of solid or fragmented ice with large open-water areas, to floes, pans, slush, or thin ice mixed with open areas. A white tone was produced by thick ice or snow-covered ice with very small or no open areas. Ice that produced grey tones was more frequent than ice that produced a white tone. Ice was observed on the Allegheny River during 10 of the 13 winters from 1972 to 1985, with the most severe ice conditions in 1976-77 when 100% of the river showed evidence of some ice cover, and 89% of the river was covered with white ice. The Monongahela River had ice during 7 winters. Grey ice and white ice were observed covering the entire Monongahela River during the 1983-84 winter. During 1976-77, grey and white ice covered 94%.

Book Synopsis Ice Conditions Along the Ohio River as Observed on Landsat Images, 1972-1985 by : Lawrence W. Gatto
Download or read book Ice Conditions Along the Ohio River as Observed on Landsat Images, 1972-1985 written by Lawrence W. Gatto and published by . This book was released on 1988 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lansat images were used to map ice distributions along the Ohio River. Ice conditions were inferred based on image grey tones interpreted using conventional photointerpretation techniques. Portions of the river that appeared black were considered ice-free. Grey tones were interpreted as ice that varied from patches of thin, snow-free solid or fragmented ice, sometimes with open areas, to floes, pans and slush. A white tone represented thick ice or snow-covered ice with few interspersed open areas. Ice that produced grey tones on the images occurred most frequently. Ice typically forms in late December or early January on the Ohio River and is gone by mid to late February. Ice was observed on the upstream section of the river from Pittsburgh to Greenup Dam during 7 of the 13 winters from 1972 to 1985, on the middle section from Greenup Dam to Cannelton Dam during 3 winters, and on the downstream section from Cannelton Dam to the Mississippi River during 4 winters. The most severe and long-lasting ice conditions occurred during the 1976-77 winter when ice covered 65% of the upstream section, 56% of the middle section, and 78% of the downstream section. Keywords: Aerial photography, Remote sensing; River ice, Winter navigation.
