| 冰河，冰川 | glacier Slow moving masses of ice which have accumulated either on mountains or in polar regions. They are found where warm, moist air or warm water meets cold air or water. They move, influenced by the force of gravity and the pressure of the ice, above the underlying slush layers and slide downhill, eventually melting at lower levels to form rivers or reaching sea-level, where they form ice shelves or fall into the water as icebergs (积聚在高山或者极地地区的缓慢移动的冰块。可以发现它们存在于有温暖潮湿的大气处或者热水流与冷水流相遇的地方。它们的移动受地心引力作用和冰的压力的影响，高于基本烂泥层和下滑坡，最终会融化到低层形成河流或到达海平面形成冰架或以冰山形式掉进海里。) |
| 冰河学 | glaciology 1. The study of all aspects of snow and ice; the science that treats quantitatively the whole range of processes associated with all forms of solid existing water. 2. The study of existing glaciers and ice sheets, and of their physical properties (1. 冰雪所有方面的研究；定量地对与各种形式的固态现存水及相关全部范围内的过程进行探讨的科学。) |
| 河产资源 | fluvial resource Any source of supply derived from a river, particularly its water, which is collected, stored and treated, then distributed for domestic, industrial, farm and other uses (所有从河流来的资源，特别是水源，被搜集，储存，处理，然后发放用于家庭，工业，农业及其他用途使用。) |
| 河口 | estuary Area at the mouth of a river where it broadens into the sea, and where fresh and sea water intermingle to produce brackish water. The estuarine environment is very rich in wildlife, particularly aquatic, but it is very vulnerable to damage as a result of the actions of humans (河口区域，此处向海洋开口，淡水和海水混合产生咸淡水。河口环境有丰富的野生生物，特别是水生的。但是由于人类活动很容易受到破坏。) |
| 河口保护区 | estuarine conservation area Estuarine area which has been reserved by legislation to protect part or all of the enclosed environment for conservation, scientific, educational and/or recreational purposes (为自然保护、科学、教育或者娱乐目的而依法保护部分或全部的封闭环境的河口区域。) |
| 河口污染 | estuary pollution Contamination of the generally broad portion of a stream near its outlet which is influenced by the tide of the water body into which it flows. Many estuaries have become badly contaminated by wastes that have been generated from heavily populated areas (在河流出口处附近的大范围的水流污染。此处污染受到水体流入海洋潮汐的影响。许多河口被人口重镇产生的污染物严重污染。) |
| 河口海洋学 | estuarine oceanography The study of the physical, chemical, biological and geological characteristics of a semi-enclosed coastal body of water which has a free connection with the open sea and within which sea water is measurably diluted with fresh water (对在半封闭海岸水体的物理，化学，生物和地理特性的研究。该水体可以自由连通到海洋，此处的海水被淡水显著稀释。) |
| 河口生态系统 | estuarine ecosystem |
| 河口生物学 | estuarine biology The scientific study or the characteristic life processes of living organisms found in a semi-enclosed coastal body of water which has a free connection with the open sea and within which sea water is measurably diluted with freshwater (对在半封闭海岸水体的科学研究或生命特征过程研究。该水体可以自由连通到海洋，此处的海水被淡水显著稀释。) |
| 河堤侵蚀 | riverbank erosion |
| 河岸土地, 土地上与河流相邻的任意倾斜面。 | bank The sloping side of any hollow in the ground, especially when bordering a river; land |
| 河岸保护 | bank protection Engineering work which aims at the protection of banks of a river, or slopes of embankments along it, from erosion by the current of flow, from floods, etc. (保护河岸或其边坡不受河水或洪水等侵蚀的工程。) |
| 河川流量状况 | discharge regime The rate of flow of a river at a particular moment in time, related to its volume and its velocity (河流在特定时间的流量，与它的水量及流速有关。) |
| 河床 | river bed The channel containing or formerly containing the water of a river (包含或原来包含河水的河道。) |
| 河水 | river water Water which flows in a channel from high ground to low ground and ultimately to a lake or the sea, except in a desert area where it may dwindle away to nothing (水流，在河道里从高处流向低处的河或海，但在沙漠中会逐渐减少到没有。) |
| 河流处理 | river disposal Discharge of solid, liquid or gaseous waste into a river (排除河里的固体、液体和气体废物。) |
| 河流污染 | river pollution The direct or indirect human alteration of the biological, physical, chemical or radiological integrity of river water, or a river ecosystem (人们直接或间接的改变河水或者河的生态系统的生物、物理、化学或放射性的完整性。) |
| 河流测量 | stream measurement The quantitative determination of the rate and amount of flow or discharge from a natural body of running water, such as a small river or brook (定量测定纯天然流水，如河流或小溪的费率，流动或排放量。) |
| 河流管理 | river management The administration or handling of a waterway or a stream of flowing water (管理或处理水道或流水的河。) |
| 河流运河 | river channelling The alteration of a natural stream by excavation, realignment, lining or other means to accelerate the flow of water (天然河的代替品，通过挖掘、重组、拉直或其它手段，以加快水的流动。) |
| 河流运输 | river transport Transportation of goods or persons by means of ships travelling on rivers (通过河里的船只来运输物品或人。) |
| 河滨地带 | riparian zone 1. Terrestrial areas where the vegetation complex and microclimate are products of the combined pressure and influence of perennial and/or intermittent water... and soils that exhibit some wetness characteristics. 2. Zone situated on the bank of a water course such as a river or stream (1. 在多种自然力、连续或间接的水域影响下，形成的植被状态，具有复杂和微气候特点的陆地区域，该区域往往具有土壤湿润的特点。2.水域(如河流、小溪)旁的区域。) |
