Comment on “ Hillslope Topography From Unconstrained Photographs
A paper recently published in Mathematical Geology raises some concerns, which need to be expressed. The paper is entitled “Hillslope topography from unconstrained photographs” by Heimsath and Farid (2002) and presents a “simple methodology to extract the high resolution 3-dimensional topographic surface from photographs taken with a hand-held camera with no constraints imposed on the camera po...

متن کاملHillslope Topography From Unconstrained Photographs1
Quantifications of Earth surface topography are essential for modeling the connections between physical and chemical processes of erosion and the shape of the landscape. Enormous investments are made in developing and testing process-based landscape evolution models. These models may never be applied to real topography because of the difficulties in obtaining high-resolution (1–2 m) topographic...
متن کاملnumerical investigation of formation of bed topography in a u shape channel bend with lateral intake with ssiim2
the mechanism of flow and sediment transport in channel bend is much complex. because of secondary current, the sediment moves away from outer bank toward inner bank and therefore outer bank of the bend is one of best positions for lateral diversion. in this paper, the mechanism of sediment transport was simulated with ssiim software in the u shape channel with lateral intake. in order to verif...
متن کاملEffects of topography on gully formation in Ilam Province
Gully erosion is one of the important forms of soil degradation especially in semi-arid areas. Gullies are occupying 13 percent of Ilam Province area. This research focused on studying the, topographic threshold of gullies, dominant process of gully initiation and development as well, in agricultural and rangeland land uses. Ilam province with 2 million hac area is located in western Iran. Ilam...
