A PHASED CREATION OF DIGITAL ELEVATION MODEL FOR HYDRODYNAMIC MODELING IN FLAT ZONES
Facta Universitatis. Series: Architecture and Civil Engineering, 2022 Hydrodynamic modeling of rivers with flood simulation requires an accurate description of the riverbed and inundation morphology. Depending on a geodetic survey method and data collected, the digital elevation models with different accuracy can be ...

MORPHOLOGICAL FILLING OF DIGITAL ELEVATION MODELS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Abstract. In this paper a new approach for a more detailed post processing and filling of digital elevation models (DEMs) in urban areas is presented. To reach the required specifications in a first step the errors in digital surface models (DSMs) generated by dense stereo algorithms are analyzed and methods for detection and classification of the ...

Geographic Information Systems (GIS)-based spatially distributed model for runoff routing [PDF]
, 1999 A method is proposed for routing spatially distributed excess precipitation over a watershed to produce runoff at its outlet. The land surface is represented by a (raster) digital elevation model from which the stream network is derived.
