Flood Modeling in the Coastal Plains and Mountains: Analysis of Terrain Resolution
The number of flood disasters has increased worldwide in recent decades. Identifying the optimal resolution or scale at which to represent digital terrain models DTMs is critical in order to improve our ability to accurately and efficiently model floods. Few studies have attempted to compare flood modeling results using different resolutions of DTMs in divergent environments. In this study floo...
متن کاملCreating a Terrain Model for Floodplain Mapping
A geographic information system ~GIS! based approach is presented for the development of a terrain model based on stream channel representation of the U. S. Army Corps of Engineers Hydrologic Engineering Center’s River Analysis System ~HEC-RAS! hydraulic model. As input, the approach requires a completed HEC-RAS simulation, a digital elevation model ~DEM!, and a GIS representation of the stream...
متن کاملHigh-Resolution Coarse-Grained Modeling Using Oriented Coarse-Grained Sites.
We introduce a method to bring nearly atomistic resolution to coarse-grained models, and we apply the method to proteins. Using a small number of coarse-grained sites (about one per eight atoms) but assigning an independent three-dimensional orientation to each site, we preferentially integrate out stiff degrees of freedom (bond lengths and angles, as well as dihedral angles in rings) that are ...
متن کاملOut-of-core Multi-resolution Terrain Modeling
In this chapter we discuss issues about Level Of Detail (LOD) representations for digital terrain models and, especially, we describe how to deal with very large terrain datasets through out-of-core techniques that explicitly manage I/O operations between levels of memory. LOD modeling in the related context of geographical maps is discussed in Chapters 3 and 4. A dataset describing a terrain c...
متن کاملError Analysis of Satellite Precipitation-Driven Modeling of Flood Events in Complex Alpine Terrain
The error in satellite precipitation-driven complex terrain flood simulations is characterized in this study for eight different global satellite products and 128 flood events over the Eastern Italian Alps. The flood events are grouped according to two flood types: rain floods and flash floods. The satellite precipitation products and runoff simulations are evaluated based on systematic and ran...
