您要查找的是不是：
- The river level rose after the rain. 雨后河里的水面升高了。
- Because of the elevation of the lake's surface compared with the river level downstream, a major difference in potential energy exists across a dam. 因为湖水水面的海拔高度，比下游河水的水面还要高，因此在水坝的两边有较大的位能差异。
- Bypassing the oxbow allows Chatham to construct a storm surge barrier which protects their section of the River, which flows along their urban edge, to prevent changes in river level. 取直河道后，查市可以修建一个防波堤。本堤可以保护河岸，驯服河水，保证河流水位长期稳定。
- A 10% fall in rain over Johannesburg and Bloemfontein will lead to a 70% drop in river levels. 约翰尼斯堡与布隆方丹（Bloemfontein）的降雨如果少了10%25，就可能造成该二地区的河川流量下降70%25。
- Moorhead lies on the other side of the Red River from Fargo, North Dakota, where river levels have reached record heights and is still rising. 穆尔黑德位于红河沿岸，与之隔河相望的两个城市法戈和北达科他州目前的水位已经达到最高记录，并持续上涨。
- They used climate change models to calculate the expected changes in rainfall across the continent and the effect they would have on river levels. 他们利用环境变迁模型去估量整个非洲大陆的降雨量，以及这种降雨量对河川所可能造成的影响。
- The water rose until it was on a level with the river banks. 河水上涨至与堤岸相平。
- The entrances are constructed in deep cofferdams in the soft soils, directly located along rivers with potentially very high river levels. 入口直接沿着可能出现很高水位的河流而建,建造在松软性土壤的深围堰中。
- The river had worn a ravine between the hills. 那条河在两山之间已造成一个深谷。
- Can we dredge the river to make it deeper? 我们能不能把这条河疏浚得深一点？
- Navigation is difficult on this river because of the hidden rocks. 因为河上有暗礁，所以在这条河上航行很困难。
- The police dredged up the parcel from the muddy river. 警方从浑浊的河水中捞出包裹。
- The analysis found that glaciers in every continent have been shrinking, permafrost is melting, the peak of river levels in spring is shifting, and lake and river temperatures are rising. 该分析发现，所有的大陆冰川已经在缩减，永久冻结带正在融化，春季水平面高度在改变，湖泊河流温度也在上升。
- It solved the control problem by maximally using finite historical data to abstract the input and output and establish its model with the records of the river levels and rain falls. 该算法极大程度地利用有限的历史数据，对模型输入输出量进行抽象，根据对历史主干河道水位、降雨等记录值的学习并建模，解决了存在的调度问题。
- A pregnant lady rescued him from the Suzhou River. 一个孕妇把他从苏州河救了起来。
- The river opens out suddenly into a broad estuary. 江面忽然开阔起来，形成一个宽广的河。
- The river flows through the city from east to west. 这条河从东到西贯穿这座城市。
- The river has gone down to its usual level now that the floods are over. 洪水己经过去，所以河水又退到原来的高度。
- Power generation has fallen because mountain snows are not melting fast enough in winter and river levels are low, hampering an economy which has not recovered from a decade-long civil war. 发电量的下降，是因为冬天山区融雪速度不够快，河水高度低，因此使尼泊尔陷入困境；这个国家先前才经历了长达十年的内战，且尚未恢复过来。
- We ferried the river on a small boat. 我们用小船渡过那条河。
