Streams do work: Measuring the work of low-order streams on the landscape using point clouds Streams do work: Measuring the work of low-order streams on the landscape using point clouds

The mutable nature of low-order streams makes regular updating of surface water maps necessary for accurate representation. Low-order streams make up roughly half the streams in the conterminous United States by length, and small inaccuracies in stream head location can result in significant error in stream reach, order, and density. Reliable maps of stream features are vital for...

Multi-scale geophysical mapping of deep permafrost change after disturbance in interior Alaska, USA Multi-scale geophysical mapping of deep permafrost change after disturbance in interior Alaska, USA

Disturbance related to fire or hydrologic processes can cause degradation of deep (greater than 1 m) permafrost. These changes in deep permafrost have the potential to impact landscapes and infrastructure, alter the routing and distribution of surface water or groundwater, and may contribute to the flux of carbon to terrestrial and aquatic ecosystems. However, characterization of deep...

Quantifying the effect of beating inferred from recorded responses of tall buildings Quantifying the effect of beating inferred from recorded responses of tall buildings

The beating phenomenon observed in recorded earthquake responses of a tall building in Japan and of two others buildings in the U.S. are examined in this paper. The objective of the paper is to discuss the significance of beating and to estimate what percentage of total shaking energy impacting a building is contributed by beating when it occurs. Beating is prominent in the prolonged...

Airborne electromagnetic imaging of permafrost for hydrologic and infrastructure studies Airborne electromagnetic imaging of permafrost for hydrologic and infrastructure studies

Permafrost is found throughout northern latitudes, and hasfar reaching implications for natural and man-made environments including hydrologic processes, landscape dynamics, ecosystems, and infrastructure. While maps of near-surface permafrost characteristics are available, relatively little is known about permafrost distributions at depth over large areas. Here, we summarize several...
