Non-linear Topographic Effects in Two-Layer Flows [PDF]
Frontiers in Earth Science, 2016 We consider the nature of non-linear flow of a two-layer fluid with a rigid lid over a long obstacle, such that the flow may be assumed to be hydrostatic. Such flows can generate hydraulic jumps upstream, and the model uses a new model of internal hydraulic jumps, which results in corrections to flows that have been computed using earlier models of ...

The Interaction Between Vegetation Change and Land–Atmosphere Heat Exchange on the Tibetan Plateau
Remote SensingVegetation–heat flux feedbacks have a great influence on ecosystems, but the interaction between them is still unclear. This is particularly critical in ecologically fragile areas, where plant growth is especially sensitive to land–atmosphere ...

The Transient Electromagnetic Response of UXO in Complex Three-Dimensional Terrain
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingIn practical exploration, the complex and diverse topographic effects are important for the processing and interpretation of EM exploration data. The interpretation of the electromagnetic data results in large errors when the influence of topographical ...
