Physical modeling and numerical modeling are two efficient analysis approaches in hydraulic engineering. The interactive application of both methods is obviously the more effective response to most of the flow problems analysis. Indeed, it enables combining the inherent advantages of both approaches, which are complementary, while being beneficial to the delays as well as the quality of the analyses. This paper presents the results of a successful application of such a combined numerical – physical study carried out by the Hydraulics engineering Laboratory of the University of Liège on behalf of Coyne et Bellier. It concerned, at the stage of detailed draft, the hydraulic study of the Taoussa Project on the Niger River in Mali. The studies, performed in less than 6 months, focused on the flow characteristics at the scale of the reservoir and the river, using the numerical approach, as well as on hydrodynamic details in the spillway using a large scale factor physical model.

The Late-Glacial - Holocene transition, around 13,000 to 8,000 years ago, is the world theatre of an ample climatic upsetting associated to a deep change of the landscapes. Around the rock-shelter of Rochedane, an archaeological site from the French Jura, the climate shifts from peri-glacial to temperate, open environment becomes progressively closed and the faunal assemblages are consequently strongly modified. In order to understand the evolutionary mechanisms implied and their different aspects, a multidisciplinary survey has been led on bones from Red Deer, Cervus elaphus, found in the shelter associated with remains of lithic industry and prehistoric art let by the hunters-gatherers during this unstable time. Isotopic geochemistry has already showed that during this period, the habitat and the diet of deers changed. Moreover, morphological studies is demonstrating that, in the same way, the size of deers seems to decrease. To complete both studies, a palaeogenetic approach was then developed to test two different alternative: do the deers found come from a single population that adapts to new ecological conditions or instead do they correspond to a succession of different populations depending on environmental conditions? The results obtained up to now do not allow to conclude between both hypotheses. However, it was demonstrated that it was possible to access authentic mitochondrial DNA sequences (control region, cytochrome b) from these prehistoric bones and to discriminate the deers of Rochedane to the individual level. Thus, this approach is promising in order to decipher in the future the possible ties between environmental, morphological and genetic changes. [less ▲]

The liquid sheet characteristics as a function of the adjuvant were measured using digital images. The droplet size distribution was measured using a Malvern particle size analyser. It appears that the dynamical surface tension plays a critical role in the spray formation. Spray formulation containing Li-700, Silwet L-77, Flofix and Actirob are characterised by a lower dynamical surface tension than those containing Tensiofix D03, Trend 90, Frigate and Break-thru S240. For the three agricultural spray nozzles tested and in comparaison with pure water, the first group shortened the length of the liquid sheet before a perforation break-up mode when the second group lengthened it slightly before a wave disintegration break-up mode. The lengthening of the liquid sheet, is followed by a diminution of the VMD. [less ▲]

Following a brief review of HELMHOLTZ's principle and of the analogy relating KIRCHHOFF's plate bending theory and a STOKES flow, such a flow is analyzed in a channel presenting periodically crenelated cavities. The results show clearly that for sufficiently deep cavities vortices are generated even at very low REYNOLDS numbers. [less ▲]

The kingfisher is generally considered as strongly territorial. However, different pairs are sometimes nesting at very close quarters. Two male kingfishers nesting along the river Meuse (Belgium) at a distance of less than 500 m were radiotagged. Their respective home range (5.2 and 7.2 km) were largely overlapping, some fishing grounds being used simultaneously by both birds. Some kind of territorial defence (a bird chasing its neighbour) has been observed in a very limitid area around the nesting places. [less ▲]
