Teshekpuk Lake is the largest lake in the Alaskan Arctic and the third largest lake in the state. Given the importance of this region to an abundance of native wildlife and expected environmental changes associated with projected sea-level rise, coastline erosion and oil and gas development, the Teshekpuk Lake Observatory (TLO) was established as an effort to gain a ...

The results of tests with a sodium chloride tracer in a shallow maturation pond in Brazil are presented. The pond – a full-scale effluent treatment unit for around 250 p.e – was 0.80 m deep with a length/width ratio of 4.3:1, and had accumulated sludge for 12 years to about 40% of the total volume. The pond is subject to daily cycles of thermal stratification/destratification, as shown by ...

Treatment of sludge in sludge treatment reed bed systems includes dewatering and mineralization. The mineralization process, which is driven by microorganisms, produces different gas species as by-products. The pore space composition of the gas species provides useful information on the biological processes occurring in the sludge residue. In this study, we measured the change in composition ...

Numerical studies regarding the influence of entrapped air on the hydraulic performance of gullies are nonexistent. This is due to the lack of a model that simulates the air-entrainment phenomena and consequently the entrapped air. In this work, we used experimental data to validate an air-entrainment model that uses a Volume-of-Fluid based method to detect the interface and the Shear-stress ...

Virkisjökull is a rapidly retreating glacier in south-east Iceland. A proglacial lake has formed in the last ten years underlain by buried ice. In this study we estimate water velocities through the glacier, proglacial foreland and proglacial river using tracer tests and continuous meltwater flow measurements. Tracer testing from a glacial moulin to the glacier outlet in September 2013 ...

In summertime a temperature stratification occurs in deep lakes – the surface water is warm, but deep down the water is cold.  This has considerable influence on the nutrient balance and the biological habitat in these lakes. Due to generally higher air temperatures induced by the climate change, both change and have effects on the life conditions of the ecosystems in the lakes. ...

Catastrophic flood events worldwide have become increasingly more frequent and their dynamics mechanism has attracted much interest as how to predict them by numerical method. As the most common phenomenon occurs in the flowing process, entrainment and deposition can significantly influence flow mobility by increasing in mass and changing in flow character. In this paper, a two-dimension ...

When the capacity of the spillway of a dam is exceeded for a given flood, overtopping occurs; in such cases potentially dangerous hydrodynamic actions and scour downstream of the dam need to be foreseen. Detailed studies of jets impinging in plunge pools from overflow nappe flows are scarce. This work addresses plunge pool flows, and compares numerical results against our own experiments. The ...

High-throughput approaches for profiling the 5′ ends of RNA degradation intermediates on a genome-wide scale are frequently applied to analyze and validate cleavage sites guided by microRNAs (miRNAs). However, the complexity of the RNA degradome other than miRNA targets is currently largely uncharacterized, and this limits the application of RNA degradome studies. We conducted a global ...
