The current lecture notes hide a primary path in th~ most typical kinds of stratified flows encountered in Environ psychological Hydraulics. lots of the flows are buoyancy flows, i.e. currents within which gravity acts on small density alterations. half I offers the fundamental ideas of stagnant, densit- stratified water, and of flowing non-miscible stratified fluids. The similarity to the (presumed) recognized open channel move, topic to a discounted gravity, is illustrated. half II treats the miscible density stratified flows. In outlining the governing equations, the robust coupling among the turbulence (the blending) and the suggest circulation is emphasised. The presentation and discussions of the fundamental governing equa tions are by means of illustrative examples. Separate chapters are dedicated to Dense backside Currents, unfastened Penetrative Convec tion, Wind-driven Stratified circulate, Horizontal Buoyancy movement and Vertical jet/plumes. half III provides a few examples of sensible difficulties solved at the foundation of data given within the current lecture notes. it's the author's event that the subjects handled in bankruptcy eight and within the next chapters are specially good suited to self-tuition, through a study-circle. ACKNOWLEDGEMENT the writer has benefited through the precious support of his col legues on the Institute of Hydrodynamics and Hydraulic Engin eering, the Technical college of Denmark, specially our librarian Mrs. Kirsten Dj¢rup, our secretary Mrs. Marianne Lewis and our technical draftsman Mrs. Liselotte Norup.

Geoscience after IT: a view of the present and future impact of information technology on geoscience
So much geoscientists are conscious of contemporary IT advancements, yet can't spend time on vague technicalities. Few have thought of their implications for the technological know-how as an entire. but the knowledge is relocating speedy: digital supply of hyperlinked multimedia; criteria to help interdisciplinary and geographic integration; new types to symbolize and visualize our ideas, and keep an eye on and deal with our actions; plummeting bills that strength the speed.

5) 0 PR(1+6) ,has been introduced. The depth integrated continuity equations are illustrated by examples in the following. We consider a fjord (Fig. 2) with a fresh water runoff R from a river located at the upstream end. On its way out of the fjord, the fresh water is continuously diluted by sea-water from below, for instance due to wind generated entrainment. Fig. 2 A fjord with entrainment (higly distorted scale) . 7) Q (where B is the interfacial width of the fjord). 9) (where is the fresh water mass deficit).

11 ) Although terrifying to look at, the energy equation for the mean motion simply states that the change in kinetic energy is due to the work done by the internal and external forces. The first two terms are the local and the convective rate of change of kinetic energy, respectively. The third term is the work done per unit time by the Reynolds' stresses v vj). 11) - shallow flows). 4. The physical interpretation of Eq. 13) is: The energy transferred from the mean flow (last term) is partly used for production of turbulent kinetic energy (PROD) and partly transferred to the ambient fluid (first term on the right hand side).
