Winds in Complex Terrain

2012
More and more onshore wind turbines are built away from flat regions near the coasts in complex (i.e. hilly or mountainous) terrain. The most favourite sites in complex terrain are at elevated positions such as hilltops. But sites in complex terrain also bear risks. In Japan, e.g.

The Complexity of Bisectors and Voronoi Diagrams on Realistic Terrains

2008
We prove tight bounds on the complexity of bisectors and Voronoi diagrams on so-called realistic terrains, under the geodesic distance. In particular, if n denotes the number of triangles in the terrain, we show the following two results. (i) If the triangles of the terrain have bounded slope and the projection of the set of triangles onto the xy-plane

Soil sampling in complex terrain

Journal of Radioanalytical and Nuclear Chemistry Articles, 1995
A procedure is described for recovering a representative soil sample from complex terrain for the purpose of determining the integrated radionuclide inventory deposited in the area. The precision of the inventory estimates is shown to be ±10% or less for137Cs and239+240Pu, and there is no statistically significant bias in the inventory estimates for ...

Modelling Terrain Complexity

2008
Terrain complexity is an important terrain feature in digital terrain analysis; however, unlike aspect or slope, terrain complexity is an ambiguous terrain feature that until now has had no optimal index to quantify it. The traditional terrain complexity definitions can be classified as statistical, geometrical, and semantic indices.

Impact Study in Complex Terrain

1981
Tracer experiments, using sulphur hexafluorid, SF6, were carried out to study the transport and diffusion of gases released from an aluminium hall in a complex valley-fjord area of western Norway. Data from these experiments were applied to study : 1) wake effects behind the aluminium hall; 2) transport and dispersion on scale of a few kilometers and 3)

Turbulent Diffusion in Complex Terrain

1982
Methods for the assessment of environmental impacts of air contaminants released and dispersed in regions of mountainous and/or hilly terrain have been a subject of increasing debate and interest over the past several years. Among the motivating concerns and issues are the following: · For a variety of economic and practical geographic reasons ...
