Research on Hull Form Design and Numerical Simulation of Sinkage and Trim for a New Shallow-Water Seismic Survey Vessel

Journal of Marine Science and Engineering
When a ship sails in shallow water, it will show different hydrodynamic performance from that in deep water due to the limitations of water depth. The shallow water effect may lead to hull sinkage and trim, increasing the risk of bottoming or collision ...

Balance, gravity waves and jets in turbulent shallow water flows

, 2009
This thesis contains a thorough investigation of the properties of freely decaying turbulence in a rotating shallow water layer on a sphere. A large number of simulations, covering an extensive range of Froude and Rossby numbers, have been carried out ...

Temporary expansion to shelf depths rather than an onshore-offshore trend: the shallow-water rise and demise of the modern deep-sea brittle star family Ophiacanthidae (Echinodermata: Ophiuroidea)

, 2013
Hypotheses on the age and possible antiquity of the modern deep-sea fauna put forward to date almost all agree on the assumption that the deep-sea fauna is largely the result of colonisation from shallow-water environments. Here, the fossil record of the

Simulation and Sensitivity Analysis of Remote Sensing Reflectance for Optically Shallow Water Bathymetry

Remote Sensing
Optically shallow waters (OSW) enable water depth retrieval through passive optical remote sensing, benefiting from the relatively low attenuation of the water column.

CNOIDAL WAVES IN SHALLOW WATER

Coastal Engineering Proceedings, 1964
The propagation of long waves of finite amplitude in water with depth to wavelength ratios less than about one-tenth and greater than about one-fiftieth can be described by cnoidal wave theory. To date little use has been made of the theory because of the difficulties involved in practical application.

Pollutant movement to shallow ground water tables from swine waste lagoons

, 1977
Th is research investigated the effect of three anaerobic swine-waste lagoons on the quality of nearby ground water. The lagoons, in the Coastal Plain region of Virginia, were located on soils with high water tables and with varying drainage ...

Aeration at overflow dams with curved surfaces by different flashboard spillways

Journal of Environmental Engineering and Landscape Management, 2014
Aeration using overflow dams is an eco-friendly and economical method of improving dissolved oxygen levels in polluted urban streams. Laboratory investigations of aeration performance in smooth spillways, as well as in parallel flashboard and interlaced ...

Modelling water temperature in TOXSWA

, 2010
A reasonably accurate estimate of the water temperature is necessary for a good description of the degradation of plant protection products in water which is used in the surface water model TOXSWA.

Estimation of phytoplankton concentration from downwelling irradiance measurements in water

, 2012
The downwelling irradiance spectrum is so far not used directly for the determination of water constituents, mainly due to the large and unpredictable fluctuations of the underwater light field induced by the water surface.

Benthic-pelagic nutrient cycling in shallow lakes : investigating the functional role of benthic microalgae

, 2007
Microbes, living on the boundary between the sediment and the water-column in lakes, can play a pivotal role in governing the magnitude and frequency of nutrient cycling.
