Convection in Small Basins

Water quality modelling for small river basins

Water quality modelling in small rivers is often considered unworthy from a practical and economic viewpoint. This paper shows instead that a simple model structure can be set up to describe the stationary water quality in small river basins in terms of carbon and nitrogen compounds, when the use of complex models is unfeasible. In short rivers point and nonpoint sources play a key role in shap...

A Review of Desilting Basins Used in Small Hydropower Plants

Small hydropower (SHP) is a renewable, efficient and eco friendly technology. Out of all the essential civil components, the desilting tank is one of the most vital part of SHP schemes, which ejects the sediment and foreign particles carried by water through the conductor system and protects the hydro mechanical equipments. With the passage of time, the desilting device has undergone modificati...

Denudation of Small Alpine Basins , Nanga Parbat Himalaya , Pakistan

Thirty-three debris fans and five small alpine basins on the south side of the rapidly uplifting Nanga Parbat Himalaya of northern Pakistan were assessed to determine how much alpine processes contribute to the overall denudation of the massif. A high-resolution digital elevation model was used to measure the volume of the small alpine fans and a few basins in the Rupal valley. These volumetric...

Salt-fingering convection in the small diffusivity ratio limit

Doubly diffusive processes play a fundamental role in many physical phenomena of substantial geophysical and astrophysical importance. Despite much research basic questions, e.g. how primary and secondary instabilities saturate and how mean fields are generated, remain unresolved. In the salt-finger regime, we use a systematic asymptotic procedure to reduce the primitive equations to a prognost...
