Upstream basin circulation of rotating, hydraulically controlled flows
The overflows of dense water from the Nordic Seas into the North Atlantic are a key element of the global meridional overturning circulation. The deep southward limb of the overturning is fed primarily by the overflows, and the transport of the deep limb is closely linked to the transport in the warmer northward currents in the upper ocean of the North Atlantic. The threat of potentially signif...
متن کاملHydraulics of floods upstream of horseshoe canyons and waterfalls
Horseshoe waterfalls are ubiquitous in natural streams, bedrock canyons, and engineering structures. Nevertheless, water flow patterns upstream of horseshoe waterfalls are poorly known and likely differ from the better studied case of a one-dimensional linear step because of flow focusing into the horseshoe. This is a significant knowledge gap because the hydraulics at waterfalls controls sedim...
متن کاملUpper circulation patterns in the Ulleung Basin
Continuous acoustic travel-time measurements from a two-dimensional array of pressure-gauge-equipped inverted echo sounders spanning the entire Ulleung Basin of the southwestern Japan/East Sea between June 1999 and July 2001 are used to examine the upper temperature and current patterns. A new method, referred to as the Residual GEM Technique, interprets the travel-time data into a three-dimens...
متن کاملObserved deep circulation in the Ulleung Basin
Records from 16 current meters and 23 pressure gauges moored near the sea floor in the Ulleung Basin of the southwestern Japan/East Sea (JES) characterized the deep circulation between June 1999 and July 2001. Mean currents range from 1 to 4 cm/s and deep pressure anomalies range from 3 to 10mbar, with horizontal correlation scales of about 40 km, and with integral time scales that range from a...
متن کاملSediments, Hydraulics and Morphology
Data of flume experiments with bed forms are used to analyze and compare different roughness predictors. In this study, the hydraulic roughness consists of grain roughness and form roughness. We predict the grain roughness by means of the size of the sediment. The form roughness is predicted by three approaches: Van Rijn (1984), Vanoni & Hwang (1967) and Engelund (1966). The total roughness val...
