It indicats that the fluvial sedimentary sequence of the flood plain of weihe river in this region is rather complete and continuous . the grain - size analysis carried out in laboratory has revealed the characteristics of the changes of weihe river during last 1300 years . based on multi - disciplinary analyses , including landform characteristics , grain - size and documents datum , the paper has attained the following important conclusions 分析了渭河三個河流沉積物剖面的粒度組成特征,剖面各層粒度分布特征,剖面粒度參數md 、 mz 、 、 sk 、 kg的變化,剖面粒度特征值- 5 、 16 、 25 、 50 、 75 、 84 、 95的跳動,并將三個剖面的粒度特征作了對比。

The depositional character of zhuxiang formation in the basin reads as follows : a series of nne alluvial fan were formed along the fault . the half - deep lake to deep lake faces appeared by west side of the fault , towards the west the saucer lake faces , shore deposit and flood plain face appeared in proper order . the depositional center of lower cretaceous was formed in eastern part of the basin , and the depositional depth was pinch - out and thinning out from the east to the west 盆地內下白堊統朱巷組沉積特征表現為:沿郯廬斷裂帶呈北北東向廣泛發育了沖積扇體系,從近斷裂帶西側出現的半深湖-深湖相,向西依次為濱淺湖相到泛濫平原相的規律性分布,沉積厚度由東向西尖滅、超覆,構成了明顯的東斷西超的盆地構造格局,表明下白堊統的沉積中心依然位于盆地東部。

The sediments of the incised valleys show an upward - fining succession , and can be grouped into four sedimentary fades : gravel lag - deposit of in - channel to partly over bank sediments of a meandering river , flood plain - estuary , estuary - shallow marine , and estuary sand bar , based on lithology , paleontology , and sedimentary textures and structures 根據巖石學、沉積結構和沉積構造特征,本區下切河谷充填沉積物具有向上變細的沉積層序,可以劃分為4個沉積相類型:河床滯留沉積物到部分曲流河沉積體系的邊灘沉積、河漫灘河口灣沉積、河口灣淺海沉積和河口灣砂壩沉積。

Qualitative analysis on the effect of flood control and engineering safety - , seizing lots of water conservancy effective adjust storage . then making water level risen and reservoir backwater enlarged in the same flow level ? effect on beach and the buildings across river , soil salinization caused by flow from a lower to a higher place and unsmooth groundwater drainage destroy of travel resource caused by disorder enclose tideland for cultivation in reservoir silt up flood plain are given , then presents enclose tideland for cultivation dyke is important cause which water level rise in reservoir 本文從青銅峽水庫泥沙淤積入手,分析水庫泥沙淤積特性和庫區圍墾堤開發利用淤積灘地的現狀,對防洪安全及工程安全的影響、侵占大量的有效調蓄庫容、造成同級流量下水庫水位抬升水庫回水上延、對沿岸及過河建筑構成影響、因水位抬升致使庫區周邊灌區地下水排水不暢乃至倒灌而造成土地鹽堿化、對水庫庫區大量淤積灘地無序圍墾造成旅游資源破壞等五方面影響的定性分析,提出庫區圍墾堤是水庫水位抬升的重要原因。

Because during the sedimentation of the flood plain - estuary fades , the conditions of sea level rising , tidal regime , sediment supply and accommodation space were suitable for the development of a tidal ridge system , the sand lenses associated with this facies may represent tidal ridge formation in the incised valley 在河漫灘河口灣相沉積期問,由于海平面上升、潮流體系、沉積物供給和可容空間條件適合一個潮流沙脊體系的發育,其中的砂質透鏡體可能代表了下切河谷內發育的潮流沙脊。

In this paper , some characteristics of flow movement and sediment transport are analyzed by using the flume experiment data . the cross section of compound channel can be divided into four regions : the undisturbed region in main channel , the interactive region between channel and plain , the undisturbed region in flood plain and the boundary region . in the undisturbed regions , the distribution of longitudinal velocity along the depth has the feature of lograithmic . whereas , in the interactive region , the longitudinal velocity does not obey the logarithmic distribution law , but it can expressed as a revised logarithmic function by using a wake function . on the basis of the kinematic equation the velocity distribution of transverse velocity is obtained . in the boundary region , the longitudinal velocity obeys the law of parabolic distribution . furthermore , according to the simplified diffusion equation , the transverse distribution of sediment concentration in the interactive region is deduced . the analysis is in good agreement with the measured data 本文根據漫灘水流的運動特點,將漫灘水流的復式斷面分為主槽平衡區、灘槽交互區、灘地平衡區及邊壁區等4個區,并給出了各區寬度的經驗公式.根據灘槽交互區垂線流速分布的變化特點,提出了附加尾流函數的對數流速分布公式.在簡化水流運動方程和泥沙擴散方程的基礎上,對灘槽交互區內垂線平均流速及含沙量沿橫向分布進行了理論分析,提出了反映灘槽水流動量交換強度的橫向渦量粘性系數及橫向擴散系數的表達式,得到了漫灘水流垂線平均流速及含沙量沿橫向分布的解析解,并與實測資料吻合較好

The comparison of the component particles of baijiaziu profile and mafangtan profile with that of modern flood plain substance of weihe river indicates that the river impetus of weihe river has gradually been getting weaker , which reveals that it has gradually been getting dryer since the last 1300 years 西安高陵白家嘴河流沉積物粒度隨深度的變化及其與渭河現代河漫灘沉積物粒度特征的對比表明,渭河近1 3ha來有流量減少,流速減慢,水深變淺的發展趨勢。

Yellow river replenish to shallow layer ground water system from side . this system is regional shallow layer ground water of hydrological cycle and this system is one of subsystem which belong to groundwater system of north china yellow river flood plain 黃河水側滲補給淺層地下水系統,是水文循環中一個局部性的淺層地下水系統,是屬華北黃河沖積平原地下水系統的一個子系統,包括黃河水系統和由它演化形成的地下水系統兩個部分。

Homeowners living in a flood plain have no hesitation appealing to the government to rebuild ( and rebuild again ) when a flood ( architecture ) wipes away their property ( law ) 居住在容易泛濫大水的平原家戶,一旦被某次洪水(基構層面)沖走了其財產(法律層面) ,他們可以毫無顧慮地要求政府為其修繕家園(或多次重修) 。

Vertically , the remaining oil in the s1 is more concentrated than other reservoir . horizontally , the remaining oil in the flood plain deposit and in the area controlled by fault is more concentrated than other area 平面上,垂直于主河道砂體的邊部及溢岸、漫灘微相的砂體被斷層夾持區域剩余油相對富集。

With forests of palms , grasslands , islands , flood plains and lagoons to be seen , tourists seeking the pleasure of adventure are sure to have one of the best experiences of their life 棕櫚樹林、草地、島嶼、沖積平原、環礁湖,讓人目不暇接,追求冒險樂趣的游人肯定會感受一次絕好的人生體驗。

And the fluvial genetic unit includes point bar , the bottom of channel , bursted fan , bursted channel , natural bank , over - bank deposits , small lake of flooding plain and swamp and so on 成因相包括點壩、河道底部沉積、決口扇及決口河道、天然堤及越岸沉積、泛濫平原小型湖及沼澤等。

A drier , rocky highland which i already described , and a rising flood plain which breaks this region into a series of small islands set amongst a shallow watery swamp area 其中一個部分是我之前描述過的巖石高地,另外的一部分則是逐漸升起的被陰暗沼澤與河流分支包圍的眾多島嶼。

Harvest from the flood plain depends on the magnitude of the river ' s runoff during the flood period . roughly once in ten years the entire flood plain would be submerged 在洪水爆發期間,泛濫平原的莊稼收成是依賴被洪水沖走量的多少,粗略估計,每十年泛濫平原就會被淹沒一次。

The various coastal features , waterfalls , potholes , bays and beaches , tombolos , flood plains , gullies , foldings , etc . are the masterpieces of natural forces 海蝕地貌、瀑布、 ?穴、海灣與沙灘、連島沙洲、泛濫平原、 ?溝、褶皺巖層等都是大自然精雕細啄的杰作。

For example , vision is obviously more useful to species inhabiting clear open waters than to those living in turbid rivers and flooded plains 舉例說明,視覺更明顯有用對于那些生活在清澈的水里的種群和那些生活早臟河和洪水泛濫的平原上的種群來講。

The banks of the yongning river in taizhou were renaturalized in connection with the design of the river park , creating additional flood plains ( page 75 ) 與永寧公園的設計相結合,本來渠化的永寧江恢復了自然形態,增加了河流的行洪灘地。

Some of the major rivers run through flood plains and there is a history of flooding problems in the area , especially in the summer rainy season 區內部分河溪流經的平原以往經常發生泛濫問題,到了夏天雨季情況尤其嚴峻。
