Performance of automated geoprocessing methods for culvert detection in remote Forest environments Can. Water Resour. J. (IF 1.7) Pub Date : 2023-01-23 Francis Lessard, Sylvain Jutras, Naïm Perreault, Éric Guilbert
Abstract Greater availability of digital elevation models (DEMs) derived from airborne light detection and ranging (LiDAR) has made it possible to map precisely hydrographic features such as streams over large watersheds. Road embankments are precisely detected, given that DEMs are especially accurate over open areas, while culverts are not. Consequently, mapped stream positions are often erroneous

Abstract The Elbow River is an eastern slope river with headwaters in the Rocky Mountains in Alberta whose major end-use is a critical source of municipal water for Calgary. Overwinter precipitation in its watershed falls primarily as snow and accumulates as snowpack until spring melt. Precipitation falls mainly as rain from May until October. The river is unregulated above Calgary’s water supply reservoir
