Surface Water Quality

Provides data on surface water quality, flow, and levels across major rivers and reservoirs in India. The Water Resources Information System, popularly known as India-WRIS, was initiated through a Memorandum of Understanding signed on December 3rd, 2008, between the Central Water Commission (CWC), Ministry of Water Resources, River Development, and Ganga Rejuvenation (now the Ministry of Jal Shakti), and the Indian Space Research Organization (ISRO), Department of Space. The aim of India-WRIS is to serve as a repository of nationwide water resources data, providing a 'Single Window' source of updated information on water resources and allied themes. It offers valuable insights into surface water, groundwater, land resources, and more. Data on the flow and level of surface water are collected across 4824 river point stations spanning all states and Union Territories in India by the Central Water Commission (CWC). This information is accessible through the Water Resources Information Systems portal. The data is categorized at administrative entities (up to districts), basin and river levels, and is presented across daily, monthly, and annual time-series since 1959. This data is particularly valuable for studies involving floods and hydrological droughts.

本数据集收录印度境内主要河流与水库的地表水水质、流量及水位数据。水资源信息系统（Water Resources Information System，简称India-WRIS）由印度中央水委会（Central Water Commission, CWC，原隶属于水资源部、河流开发与恒河振兴部，现更名为贾尔沙克蒂部）与印度空间研究组织（Indian Space Research Organisation, ISRO，空间部）于2008年12月3日签署的谅解备忘录启动建设。India-WRIS的建设目标是打造全国性水资源数据仓储库，为水资源及相关主题的最新信息提供“单一窗口”获取渠道。该系统可提供地表水、地下水、土地资源等多领域的宝贵参考数据。印度中央水委会（CWC）在印度所有邦及中央直辖区内的4824个河道监测站点采集地表水流量与水位数据，相关信息可通过水资源信息系统门户网站查询获取。数据按行政单元（最低至区县级别）、流域及河道层级进行分类，并涵盖1959年以来的日、月、年时间序列数据集。该数据集对于洪水与水文干旱相关研究具有极高的应用价值。
