不同洪水重现期下橡胶坝调控对洪水风险的影响

现有针对河湖水系连通伴生风险分析的方法或不具备物理过程模拟,或缺乏对风险随机性的探讨。以沂沭河水系连通工程为例,在水力学模型的基础上,考虑连通河网不同河流洪峰相关性,创建随机水情条件下河湖水系连通伴生风险分析模型。通过1 200组水情条件,对沂沭河水系上游进行洪水过程模拟,针对橡胶坝可能造成的洪峰叠加问题,提出不同洪水重现期下橡胶坝运行调度风险管控建议。结果表明:① 50年一遇与100年一遇洪水重现期条件下,均呈现出橡胶坝坝址处水位风险极高（概率P>0.8）,流速风险较低（P < 0.3）的规律,且每当橡胶坝高度升高25%的设计坝高时,沂河与沭河坝前水位风险皆提高约70%,沭河坝址处流速风险降低约50%。②若在汛前塌坝下泄蓄水,人为洪峰的叠加会使沭河中下游河段产生极高风险。③通过划分水位、流速综合洪水风险安全域,洪水重现期50年一遇时,建议沂沭河橡胶坝在汛前调节至低于50%设计坝高,且控制沭河水深和流速分别在12 m和2.23 m/s以内,可以降低水位和流速风险至低风险（P < 0.4）;洪水重现期100年一遇时,需将橡胶坝调至25%设计坝高以下,或者汛前尽早缓慢塌坝下泄蓄水,才能有效降低沂沭河水系防洪压力。

淮河流域沂沭泗河1730年洪水

1730年(清雍正八年)在我国淮河流域沂、沭、泗河地区发生了一次特大洪水,暴雨洪水范围广,洪峰高,洪量大,灾情重,实为该地区数百年来所罕见。1949年以后,因工作需要,几个单位先后在沂、沭河上进行了洪水调查,共有13个调查河段、推算洪峰流量河段9个,并查阅了地方志和故宫文献档案,做了

沂沭河1974年8月暴雨洪水简介

1974年8月,第12号台风在我国的福建省登陆后,进入内陆变为台风低压并继续北上,台风倒槽与西风槽相接造成苏、鲁、皖连续3～5天的特大暴雨,使沂沭河及运河均出现特大洪水,其中沭河出现近二百五十年以来的最大洪水,经过还原计算的洪峰流量相当于百年一遇;沂河及运河就其一天及三天的洪量来说亦是解放以来最大的。两河洪水在骆马湖汇     

山东中部1974年8月暴雨洪水简介

1974年12号台风导致华东地区8月11～13日发生一次大面积暴雨,这次暴雨波及山东、江苏、安徽、河南四省。雨区南自大别山区,北至山东渤海边,东西宽约150公里,南北长约850公里,超过100毫米以上的面积达15万公里~2。此次暴雨在淮河干流并未造成很大洪水,但在山东潍、沭河却造成了近百年来的特大洪水,潍、沂、沭河沿河两岸造成了很大灾害。现将1974年8月发生的暴雨洪水简介如下,供参考。

山东金刚石

很久以前就有过关于山东出产金刚石的记载,但是对山东金刚石产地正式进行调查工作,却只是在解放以后才开始的。经过几年的工作,在沂沭河下游已经证实了一些具有工业意义的金刚石砂矿床。本文是根据在普查时所获得的一批近二百颗金刚石的资料整理出来的。由于在野外,不可能用精密的仪器来进一步观察金刚石晶体上的各种地质现象,因而说,这仅是初步提供的资料。下面就山东金刚石的矿物分作几方面来叙述:

The terrestrial fauna of the Late Triassic Pant-y-ffynnon Quarry fissures,South Wales,UK and a new species of Clevosaurus (Lepidosauria: Rhynchocephalia)

Pant-y-ffynnon Quarry in South Wales yielded a rich cache of fossils in the early 1950s, including articulated specimens of new species (the small sauropodomorph dinosaur Pantydraco caducus and the crocodylomorph Terrestrisuchus gracilis), but no substantial study of the wider fauna of the Pant-y-ffynnon fissure systems has been published. Here, our overview of existing specimens, a few described but mostly undescribed, as well as freshly processed material, provides a comprehensive picture of the Pant-y-ffynnon palaeo-island of the Late Triassic. This was an island with a relatively impoverished fauna dominated by small clevosaurs (rhynchocephalians), including a new species, Clevosaurus cambrica, described here from a partially articulated specimen and isolated bones. The new species has a dental morphology that is intermediate between the Late Triassic Clevosaurus hudsoni, from Cromhall Quarry to the east, and the younger C. convallis from Pant Quarry to the west, suggesting adaptive radiation of clevosaurs in the palaeo-archipelago. The larger reptiles on the palaeo-island do not exceed 1.5?m in length, including a small carnivorous crocodylomorph, Terrestrisuchus, and a possible example of insular dwarfism in the basal dinosaur Pantydraco.     

Définition d'une limite multicritère ; stratigraphie du passage Campanien–Maastrichtien du site géologique de Tercis (Landes,SW France)Definition of a multi-criteria boundary; stratigraphy of the Campanian–Maastrichtian interval of the geological site at Tercis (Landes,SW France)

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

The effect of water on accessory phase solubility in subaluminous and peralkaline granitic melts

The solubilities of columbite, tantalite, wolframite, rutile, zircon and hafnon were determined as a function of the water contents in peralkaline and subaluminous granite melts. All experiments were conducted at 1035 °C and 2 kbar and the water contents of the melts ranged from nominally dry to approximately 6 wt.% H₂O. Accessory phase solubilities are not affected by the water content of the peralkaline melt. By contrast, solubilities are affected by the water content of the subaluminous melt, where the solubilities of all the accessory phases examined increase with the water content of the melt, up to 2 wt.% H₂O. At higher water contents, solubilities are nearly constant. It can be concluded that water is not an important control of accessory phase solubility, although the water content will affect diffusivities of components in the melt, thus whether or not accessory phases will be present as restite material. The solubility behaviour in the subaluminous and peralkaline melts supports previous spectroscopic studies, which have observed differences in the coordination of high field strength elements in dry vs. wet subaluminous granitic glasses, but not for peralkaline granitic glasses. Lastly, the fact that wolframite solubility increases with increasing water content in the subaluminous melt suggests that tungsten dissolved as a hexavalent species.     

Late Wuchiapingian (Late Dzhulfian,early Late Permian) limestone olistolites within the Tertiary flysch of Glypia Unit (Mount Parnon,central–eastern Peloponnesus,Greece)

Some olistolites reworked in a Tertiary flysch of Mount Parnon (Peloponnesus, Greece) exhibit a Late Permian assemblage, dominated by Paradunbarula (Shindella) shindensis, Hemigordiopsis cf. luquensis and Colaniella aff. minima. This association corresponds to the Late Wuchiapingian (=Late Dzhulfian), a substage whose algae and foraminifera are generally little known. Contemporaneous limestones crop out in the middle part of the Episkopi Formation in Hydra, but they are rather commonly reworked in Mesozoic and Cainozoic sequences. The palaeobiogeographical affinities shared by the foraminiferal markers of Greece, southeastern Pamir, and southern China, are very strong (up to the specific level), and are congruent with the Pangea B reconstructions.
