Geography of artificial levees in the United States, The
Connectivity between different parts of the landscape is an important theme for river ecosystem functions. Recent advances in conceptual models of river ecosystems, computing power, and data availability, resolution, and ... -
Post-glacial alluvial valley dynamics of the South Fork Cache la Poudre River Valley at the Colorado State University Mountain Campus
Wide valley bottoms are physically important sediment storage sites where alluvial records of past landscape dynamics may be preserved. Following deglaciation after the Last Glacial Maximum (LGM), unconfined valleys in the ... -
Facies architecture and depositional processes influencing carbonate facies belt development along a low-inclined shelf, Huk Formation, Norway, and Komstad Formation, Sweden
Heterozoan, or temperate to cool water, carbonate successions can provide unique obstacles to establishing a typical depositional model that can be universally applied. Unlike their tropical realm counterparts, these ... -
Variation in clinopyroxene texture, composition, and crystallization depth of Late Cretaceous to Early Eocene lamprophyric rocks from alkaline calc-alkaline magmatic complexes of Montana, USA
Lamprophyres are spatially and temporally associated with many types of hydrothermal ore deposits and have been argued to be a marker in mineral exploration. A reconnaissance study of lamprophyric rocks in central Montana, ... -
Channel initiation in the semiarid Colorado Front Range
The channel head, defined as the upstream boundary of concentrated water flow and sediment transport between definable banks, represents the transition from hillslope processes to fluvial processes. The ability to delineate ... -
Timing, kinematics, and tectonic significance of strike-slip fault systems in the Atacama Desert of northern Chile and the Lower Colorado River corridor, U.S.A.

Evaluating the impact of deep-water channel architecture on the probability of correct facies classification using 3D synthetic seismic data
Modeling studies of bed-to geobody-scale architecture in deep-water channel deposits reveal that channel element stacking patterns and internal architecture strongly control connectivity. This architecture is critical to ... -
Structural analysis along the Ouray fault, southwestern Colorado: implications for the kinematic development of the late Paleozoic Ancestral Rocky Mountains
The Ouray fault in southwest Colorado provides insight into the geometry and kinematics of deformation during the formation of the late Paleozoic Ancestral Rocky Mountains (ARM). The Ouray fault strikes WNW-ESE and dips ... -
Sedimentology of an Upper Ordovician (late Katian-Hirnantian) deep shelf mudstone exposure preceding massive sea level drop - Mount Ålleberg, Västergötland, Sweden
The deposition of siliciclastic mudstones in a passive margin deep shelf environment has not been explored well in literature. The upper Ordovician succession at Mt. Ålleberg, Västergötland (southern Sweden) is such a ... -
Streamflow synthesis and water allocation by water right priorities
A computerized streamflow model was developed that allocates water by the doctrine of prior appropriations. The function of the model is to simulate the impacts of physical or legal changes in a stream system managed on ... -
Low-cost data loggers for use with the conductivity mass balance method to estimate baseflow at snowmelt-dominated headwater streams in northwestern Colorado
Groundwater contribution to streamflow (baseflow) in snowmelt-dominated headwater streams, particularly following the snowmelt peak, is crucial for sustaining late season flow necessary for maintaining instream functions ... -
Characterization and prediction of long-term arsenic mobility, dissolution, and kinetic behavior in arsenic contaminated floodplain deposits of Whitewood Creek and the Belle Fourche River, South Dakota
From 1877 to 1977, the Homestake Mine discharged over 100 million tons of arsenic-rich mine-wastes from Lead, South Dakota into Whitewood Creek (WWC), which joins the Belle Fourche River (BFR). Arsenopyrite and other ... -
Rift to drift transition in the southwest Australian deepwater Mentelle Basin
The Mentelle Basin is a deepwater polyphase basin located off of the southwest margin of Australia that formed during Late Jurassic and Early Cretaceous breakup of Gondwana. It is underlain by highly extended continental ... -
Distributed seasonal and annual mass balance measurements of Wolverine Glacier, Alaska, using geodetic surveys and emergence velocities
Glaciers are key components of human-environmental systems worldwide. They are a source of fresh water for human consumption, crop irrigation, and hydroelectric power even during times of drought. Glaciers promote environmental ... -
Wood-induced stream channel complexity as a driver of transient storage
Rivers are naturally diverse, heterogeneous systems. This spatial heterogeneity is driven by inputs into a river corridor including water, sediment, large wood, coarse particulate organic material (CPOM), and dissolved ... -
Quantifying scale relationships in snow distributions
Spatial distributions of snow in mountain environments represent the time integration of accumulation and ablation processes, and are strongly and dynamically linked to mountain hydrologic, ecologic, and climatic systems. ... -
Uncertainty in hydrological estimation
Detailed hydrometeorologic analyses and uncertainty assessments are needed to aid water resources decision-making, to account for upstream-downstream linkages and dominant process scale for integrated land and water resources ... -
Evaluating the impact of hierarchical deep-water slope channel architecture on fluid flow behavior, Cretaceous Tres Pasos Formation, Chile
Channelized deep-water reservoirs inherently contain sub-seismic scale heterogeneity, resulting in uncertainty when evaluating reservoir connectivity and flow patterns. Stratigraphic architectural features, including stacked ... -
Evidence for a rotation in asthenospheric flow in northwest Canada: insights from shear wave splitting
The Mackenzie Mountains (MM) of northwest Canada are an actively uplifting, seismogenic salient of the northern Canadian Cordillera that lie 750 km NE of the nearest plate boundary. We present new shear wave splitting ... -
Hydrogeophysical investigation of unconfined aquifer drainage behavior using temporal microgravity and water level data
Unconfined aquifers are commonly characterized by an analysis of water level changes in response to groundwater pumping during an aquifer test. Traditional analytical models predict the rate and extent of water level changes ...
