Yunca : Indian of a group of South American tribes of which the Chimus and the Chinchas are the most important. The Yunca civilisation developed a pre-Inca culture on the coast of Peru. 1 Introduction Water^ constitutes the primary constituent of the oceans, theriversand streams, and subterraneous fluids on the Earth. e. 25 per cent of the water volume being in the oceans (BERNER and BERNER 1987).

The lift force is proportional to the flow velocity times the rotation speed of the cylinder. g. SWANSON 1961). MANNING : Robert MANNING (1816-1897) was Chief Engineer of the Office of Public Works, Ireland. In 1889, he presented two formulae (MANNING 1890). One was to become the so-called 'Gauckler-Manning formula' but Robert MANNING did prefer to use the second formula that he gave in his paper. G. GAUCKLER (GAUCKLER 1867). MARIOTTE : Abbe Edme MARIOTTE (1620-1684) was a French physicist and plant physiologist.

For a spherical bubble of diameter d^^, the increase of internal pressure necessary to balance the tensile force caused by surface tension equals : AP = A'^ald^^ where a is the surface tension. g. detergent) that, when added to a liquid, reduces its surface tension thereby increasing its wetting property. e. abrupt increase or decrease in depth). An abrupt increase in flow depth is called a 'positive surge' while a sudden decrease in depth is termed a 'negative surge'. A positive surge is also called (improperly) a 'moving hydraulic jump' or a 'hydraulic bore'.
