Protection of the diversity of river morphology character;2. Generally, the effect of Coriolis force on the river morphology in low latitude regions is not so much noticed as that in the high latitude regions.

对高纬地区河流地貌的塑造作用具明显效应，在低纬地区，由于这种力随纬度降低而减弱，加之其它力作用的干扰而表现不明显，但在桂林特定的岩溶水文动力学条件下，这种力对漓江岩溶区段河流地貌的塑造却有明显效应。

The change of grain size was mainly caused by the fluvial power, which was related with the climate change in Weihe River watersheds.

沉积物的粒度变化主要是由河流水动力条件的变化造成的，而河流水动力条件又与渭河流域区域内的气候变化有关。

Scoyenia ichnofacies widely occurs in flood plains and the transitional belts of rivers and lakes, Termitichnus ichnofacies owns features of continental environment, Rusophycus ichnofacies made its appearance in river channel and levee sub-environments of relative high energy, Arenicolites ichnofacies colonized on the surface of hummocky sandstones of storm deposits.

Scoyenia遗迹相广泛发育在洪泛平原、冲积平原以及河流与湖泊的过渡地带，Termitichnus遗迹相是陆地沉积环境的特征，Rusophycus遗迹相出现在河流沉积环境河道、堤岸等能量较高的亚环境。Arenicolites遗迹相在开阔湖风暴沉积的丘状砂岩层面上拓殖，主要由机会分子构成。

As in other places, rivers in Africa often make for more neighbourliness, not less; the more countries a river passes through, the greater the regional co-operation.

正如在其他地区那样，河流贯穿的非洲大陆往往是一荣俱荣的邻伴居多，争锋造次的敌国要少。一条河流贯穿的国家越多，地区性合作也就越大。

The Eyak, Tlingit, Haida and Tsimshian live in south central Alaska and the southeast Panhandle of the state. They depend upon the ocean and rivers for their food and means of travel. Although they have similar cultures, their languages are different.

Eya k、 Tlingi t、 Haida 及 Tsimshian 都住在阿拉斯加的中南部和阿拉斯加的潘汉德尔市东南部，他们都依赖海洋及河流维生，也通过海洋及河流四处迁徙；虽然他们都拥有相似的文化，但各自的语言却不相同。

He who sits still in a house all the time may be the greatest vagrant of all; but the saunterer, in the good sense, is no more vagrant than the meandering river, which is all the while sedulously seeking the shortest course to the sea.

一直待在家里不出来的人，可能是最伟大的漂流者。然而，从某种意义上说，漫步者比蜿蜒的河流更漂泊不定，因为河流始终坚定不移地寻找汇人海洋的最短路线。

In this paper a method for calculating risk of exceeding criterionin river was put forward on the basis of mathematical simulation analysis for toxicants'leaking behaviour.

在对有毒物质河流泄漏行为进行数学模拟分析的基础上，提出了一种计算河流断面超标风险的方法。为进一步确保饮用水水质的安全提供了可靠保证

Born in the icy headwaters of rivers on the east coast of North America, Britain, Iceland, Ireland, Poland, Portugal, Russia, Scandinavia and Spain, baby salmon, or parr, swim far out to sea to fatten up on herring and sprat.

鲑鱼繁衍于冰雪覆盖的河流源头，这些河流分布在北美东海岸，不列颠，冰岛，爱尔兰，波兰，葡萄牙，俄罗斯，斯堪地纳维亚半岛，以及西班牙。鲑鱼幼仔，或更大点的个体，就从远离大海的河源溯水而来，靠捕食鲱鱼以及鲱类小海鱼得以成长。

There were ,of course, numerous state and some federal laws intended to protect America's rivers and streams from excessive industrial pollution and to guard wildlife from the depredations of man .

当然也有，许多国家和旨在保护美国的联邦法律和一些河流从过剩的工业污染河流和看守人的劫掠从野生动物。

Forecast of river runoff has been one of the objectives that hydrologists persevere to pursue for decades. However, because of different sources of water vapor throughout the country and the features of different rivers, using a common set of forecasting options can not give an accurate and timely prediction for flood prevention and drought controlling capabilities.

多年来对河流径流量进行预报，一直是水文工作者追求的目标之一，但由于全国各地水汽来源不同，河流特性千差万别，因而用一套通用的预报方案不能够准确、及时地预报，以达到防洪抗旱的能力。
