▼ In the past, the suspended sediment concentration (SSC) was mainly measured by the optical backscattering device (OBS) and water sample filtration. However, there has been a new development that user is based on the acoustics backscattering (ABS) to measure the SSC in the world. The acoustic instruments have some advantages that the optical ones do not have. For example, acoustic instruments are not effected by high turbidity, biofouling and high viscosity in the water. Acoustic instruments have high spatial and temporal resolutions. And they can immediately indicate the SSC changes than the water sample filtration method. Therefore, in this study we used the multi-frequency acoustics instrument (AQUAscat-1000) to investigate the relations of the suspended sediment size and concentration to the acoustic characteristics. The results are separated into two parts: (1) The calibration process in the flume. (2) The acoustic results in the field experiment. In the first part, we examined the range of preferred bin size with respect to the different frequencies as well as the condition in the flume, and determine that conclude the 20 mm is the best range for our case. In addition, the gain should be used when the maximum SSC is less than 100 mg/l and vice versa. Therefore, in the field case around the river mouth, the signal gain should be turned off due to high concentrations. According to the sensitivity of the backscatter intensity of different frequencies to the suspended particle sizes, multiple frequencies are needed to derive the SSC when the sediment size becomes smaller. The last point in this part is the comparison of the results between the acoustics and optical instruments. When the suspended particles in the water column are transparent, the optical measurement of the SSC is underestimated, but the acoustic method is not. The result of the field experiment in 2009 showed that the AQUAscat-1000 is a better instrument to quantify SSC than the optical instruments. The SSC increase caused by the bottom sediment re-suspension was due to the wave shear. In the 2011 experiment, although the acoustic results overestimated the SSC at some points but they still had higher relation and significance with water sample data than the optical measurements. The SSC increase caused by the bottom sediment re-suspension was due to the current shear. Advisors/Committee Members: Linus Y.S Chiu (chair), James T.

▼ Durant le IVe millénaire, la Mésopotamie et ses voisins ont été reliés via un vaste réseau commercial, établi par des Urukéens lors de leur expansion en Iran et dans le Nord mésopotamien. À la fin du IVe et au début du IIIe, la Mésopotamie et ses voisins ont connu une phase de crise dont les causes nous sont toujours obscures en raison de l’absence des documents écrits remontant à cette phase. A cette phase, le réseau commercial urukéen et la colonisation urukéenne en Iran et en Mésopotamie du Nord, s’étant effondrés, les sites urukéens ont été abandonnés, ainsi qu’un grand nombre de sites indigènes qui ont été abandonnés. Le contact entre le Nord et le Sud mésopotamien fut suspendu. Pourtant, d’autres sites furent fondés que ce soit en Iran ou en Mésopotamie. Bien que la culture céramique mésopotamienne ne se soit modifiée profondément à cette phase cruciale, des traditions peintres réapparaissent soudainement alors que les Mésopotamiens les avaient abandonnées depuis 9 siècles (au Post-Obeid). Trois aires à céramique peinte apparaissent en Mésopotamie : en Irak du centre, de l’Est, du Nord (horizon de Ninive 5) et l’Iran a employé massivement la peinture. Cependant, le Sumer a conservé les traditions urukéennes qui ne connaissent pas de peinture. A noter que la peinture en Iran a été employée avant et durant l’expansion urukéenne. De plus, il semble avoir existé un corridor de contact reliant le West iranien aux trois zones à peinture en Mésopotamie. Mais comment peut-on expliquer ce phénomène de la réapparition de la peinture en Mésopotamie centrale et du Nord : s’agit-il des déplacements des groupes iraniens en Mésopotamie, ou des simples influences ? On ne peut pas traiter de la question de la fin du IVe/début du IIIe millénaire sans confronter, d’une part au problème concernant le destin des Urukéens. Ces derniers ont vécu plus de 4 siècles dans la périphérie durant l’expansion. Et d’autre part on est confronté au problème de la fondation des sites urbain aux touts début du 3e millénaire (Mari, Terqa, Kharab Sayyar et Chuera).Pour répondre à ces questions, nous avons choisi des sites-clés en Iran et en Mésopotamie. Leur céramique (et d’autre matériel) est étudié tout d’abord dans leur position stratigraphique, site par site, puis selon leur répartition dans l’espace. Au même temps, cette étude strato-céramique a été combinée avec une étude portée sur les changements dans l’occupation dans l’espace (abandon et fondation) et sur les transformations culturelles, surtout en Iran du Nord-Ouest et de l’Ouest où le phénomène de l’expansion transcaucasienne s’étend jusqu’au Kermanshah et le Nord du Luristan dans le Zagros central).Basant sur des comparaisons céramiques et sur d’autres aspects archéologiques, nous avons tenté de corréler entre la stratigraphie des sites étudiés. Nous avons évité de faire d’un site ou d’une région le « centre du monde ». Nous avons plutôt regardé chaque site et région à partir de ses voisins. A la fin de chaque partie ou chapitre, nous avons relié entre les régions étudiées, du point de… Advisors/Committee Members: Rouault, Olivier (thesis director).
