Flow History Effects on River Bifurcation Dynamics in a Himalayan River

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Dynamic gravel bed rivers experience frequent changes in channel position and flow distribution between branches, which can alter the location and extent of flooding. Changes in flow routing can significantly impact livelihoods, habitats and infrastructure in adjacent floodplains. Here, we test whether variations in seasonal discharge patterns

Unsteady aerodynamic calculations of flappping wing motion [PDF]

, 2007
Bu tez çırpan kanat hareketinin havada asılı kalma modunu inceleyerek gelecektekimikro hava araçları uygulamalarına ısık olmayı amaçlamıstır. Bu çalısmada, düsükReynolds sayısında kanat kesitinin sekli, kalınlığı, kambur dağılımı gibi geometricparametrelerin ve bunların yanında çırpan kanat hareketinin aerodinamik kuvvetkatsayılarının ve girdap olusum ...

Wind Forcing and Warm Water Upwelling in a Recurring Beaufort Shelf Polynya

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract The Beaufort Shelf has historically been reported to exhibit limited polynya activity in winter. Yet, recent satellite observations show episodic recurrence of a large polynya west of Mackenzie Canyon, a site of significant shelf‐basin exchange.

The Role of Basal Roughness and Assemblage Grain‐Size Distribution in Shaping Granular Rheology and Basal‐Force Signals

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract We present idealized 3‐D discrete element simulations exploring how varying boundary roughness and grain‐size distribution affect bulk granular‐rheology and basal‐force distributions. Boundary roughness has a direct control on the internal static friction coefficient.

Experimental Verification of a Two‐Dimensional Inverse Method for Turbidity Currents Using a Deep Neural Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Turbidites have been widely studied as indicators of the occurrences and magnitudes of paleo‐tsunamis and paleo‐earthquakes. Inversion to estimate flow conditions from turbidites offers valuable insights into the magnitudes of paleo‐seismic and tsunami events.
