| Abstract from DBPedia | Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water', and -λογία (-logía) 'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management. Hydrology subdivides into surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management, and water quality, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects within those fields. Hydrological research can inform environmental engineering, policy, and planning.水文学（すいもんがく、英語: hydrology）とは、地球上の水循環を主な対象とする地球科学の一分野であり、主として、陸地における水をその循環過程から、地域的な水のあり方・分布・移動・水収支等に主眼をおいて研究する科学である。水文科学（英語: hydrologic science）ともよぶ。 研究対象は、水の供給源としての降水の地域的・時間的分布特性、蒸発、浸透、陸水や地下水の移動等が中心となる。 (Source: http://dbpedia.org/resource/Hydrology) |
