Environmental controls on observed spatial variability of soil pore water geochemistry in small headwater catchments underlain with permafrost

Autor: N. A. Conroy, J. M. Heikoop, E. Lathrop, D. Musa, B. D. Newman, C. Xu, R. E. McCaully, C. A. Arendt, V. G. Salmon, A. Breen, V. Romanovsky, K. E. Bennett, C. J. Wilson, S. D. Wullschleger

Publikováno v: The Cryosphere, Vol 17, Pp 3987-4006 (2023)

Soil pore water (SPW) chemistry can vary substantially across multiple scales in Arctic permafrost landscapes. The magnitude of these variations and their relationship to scale are critical considerations for understanding current controls on geochem

High‐Resolution Maps of Near‐Surface Permafrost for Three Watersheds on the Seward Peninsula, Alaska Derived From Machine Learning

Autor: E. A. Thaler, S. Uhleman, J. C. Rowland, J. Schwenk, C. Wang, B. Dafflon, K. E. Bennett

Publikováno v: Earth and Space Science, Vol 10, Iss 12, Pp n/a-n/a (2023)

Abstract Permafrost soils are a critical component of the global carbon cycle and are locally important because they regulate the hydrologic flux from uplands to rivers. Furthermore, degradation of permafrost soils causes land surface subsidence, dam

Spatial patterns of snow distribution in the sub-Arctic

Autor: K. E. Bennett, G. Miller, R. Busey, M. Chen, E. R. Lathrop, J. B. Dann, M. Nutt, R. Crumley, S. L. Dillard, B. Dafflon, J. Kumar, W. R. Bolton, C. J. Wilson, C. M. Iversen, S. D. Wullschleger

Publikováno v: The Cryosphere, Vol 16, Pp 3269-3293 (2022)

The spatial distribution of snow plays a vital role in sub-Arctic and Arctic climate, hydrology, and ecology due to its fundamental influence on the water balance, thermal regimes, vegetation, and carbon flux. However, the spatial distribution of sno

New insights into the drainage of inundated ice-wedge polygons using fundamental hydrologic principles

Autor: D. R. Harp, V. Zlotnik, C. J. Abolt, B. Busey, S. T. Avendaño, B. D. Newman, A. L. Atchley, E. Jafarov, C. J. Wilson, K. E. Bennett

Publikováno v: The Cryosphere, Vol 15, Pp 4005-4029 (2021)

The pathways and timing of drainage from the inundated centers of ice-wedge polygons in a warming climate have important implications for carbon flushing, advective heat transport, and transitions from methane to carbon dioxide dominated emissions. H

Using MODIS estimates of fractional snow cover area to improve streamflow forecasts in interior Alaska

Autor: K. E. Bennett, J. E. Cherry, B. Balk, S. Lindsey

Publikováno v: Hydrology and Earth System Sciences, Vol 23, Pp 2439-2459 (2019)

Remotely sensed snow cover observations provide an opportunity to improve operational snowmelt and streamflow forecasting in remote regions. This is particularly true in Alaska, where remote basins and a spatially and temporally sparse gaging network

Climate-driven disturbances in the San Juan River sub-basin of the Colorado River

Autor: K. E. Bennett, T. J. Bohn, K. Solander, N. G. McDowell, C. Xu, E. Vivoni, R. S. Middleton

Publikováno v: Hydrology and Earth System Sciences, Vol 22, Pp 709-725 (2018)

Accelerated climate change and associated forest disturbances in the southwestern USA are anticipated to have substantial impacts on regional water resources. Few studies have quantified the impact of both climate change and land cover disturbance

Hydroclimatic variability and predictability: a survey of recent research

Autor: R. D. Koster, A. K. Betts, P. A. Dirmeyer, M. Bierkens, K. E. Bennett, S. J. Déry, J. P. Evans, R. Fu, F. Hernandez, L. R. Leung, X. Liang, M. Masood, H. Savenije, G. Wang, X. Yuan

Publikováno v: Hydrology and Earth System Sciences, Vol 21, Pp 3777-3798 (2017)

Recent research in large-scale hydroclimatic variability is surveyed, focusing on five topics: (i) variability in general, (ii) droughts, (iii) floods, (iv) land–atmosphere coupling, and (v) hydroclimatic prediction. Each surveyed topic is suppl

The evolution of process-based hydrologic models: historical challenges and the collective quest for physical realism

Autor: M. P. Clark, M. F. P. Bierkens, L. Samaniego, R. A. Woods, R. Uijlenhoet, K. E. Bennett, V. R. N. Pauwels, X. Cai, A. W. Wood, C. D. Peters-Lidard

Publikováno v: Hydrology and Earth System Sciences, Vol 21, Pp 3427-3440 (2017)

The diversity in hydrologic models has historically led to great controversy on the correct approach to process-based hydrologic modeling, with debates centered on the adequacy of process parameterizations, data limitations and uncertainty, and co
