Characterization and Evaluation of Elevation Data Uncertainty in Water Resources Modeling with GIS

Wu, Simon; Li, Jonathan; Huang, G. - In: Water Resources Management 22 (2008) 8, pp. 959-972

Grid based digital elevation models (DEM) are commonly used in water resources modeling. The quality of readily … available DEM, however, varies from source to source in terms of horizontal resolution and vertical accuracy which are the two … presenting DEM processing processes in distributed and semi-distributed hydrologic analyses. It is very difficult to examine the …

Estimation of Geomorphological Parameters of Lower Zab River-Basin by Using GIS-Based Remotely Sensed Image

Saeedrashed, Y.; Guven, A. - In: Water Resources Management 27 (2013) 1, pp. 209-219

The Lower Zab watershed is one of the most important catchment areas in the northern region of Iraq, as it includes large dam which is called Dukan Dam. Besides this, there are four other catchment areas, which are the Greater Zab (Upper Zab), Diyala, Khabur, and Uzem. During the last few...

Wind speed spatial estimation for energy planning in Sicily: A neural kriging application

Cellura, M.; Cirrincione, G.; Marvuglia, A.; Miraoui, A. - In: Renewable Energy 33 (2008) 6, pp. 1251-1266

One of the first steps for the exploitation of any energy source is necessarily represented by its estimation and mapping at the aim of identifying the most suitable areas in terms of energy potential. In the field of renewable energies this is often a very difficult task, because the energy...

DEM simulation of small particles clogging in the packing of large beads

Remond, S. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 21, pp. 4485-4496

The percolation of small particles through a periodic random loose packing of large beads is studied numerically with the Distinct Element Method. The representativity of periodic mono-sized sphere packing of varying system size was first studied by comparing their pore size distributions and...
