The State Water Cadastre (SWC) was initiated in the 2003 by the Armenian Water Resources Management Agency. The SWC was initiated according to Water Code demands for complete data of surface and ground waters, water users, water quality and water quantity. The State Water Cadastre (SWC) is a permanent operating system. It maintains a comprehensive record of the following data:
- Quantity and quality of water resources;
- Catchment areas;
- Materials extracted from water basins; Water intake;
- Composition and size of biological resources;
- Water users; Water use permits;
- Water system use permits.
The SWC is authorised and supported by the Water Code. The main functions of the SWC are to record documents and register assignments for planning, implementing and managing water resource monitoring. It also records water structures, such as dams, canals, reservoirs.
In the period of 2005-2006, the Government of Republic of Armenia, from the state budget and with the technical help of USAID, provided funding for development of the GIS component of the SWC and water balance applications.
The SWC provides preliminary data on the location, quantity and quality of water resources based on the type of water use. It offers to assess the type of water system used for water storage, transportation, distribution, treatment, and wastewater removal. The SWC also enables policy-makers to predict the sustainability of water resources, the security of water systems, and to warn of potential hazards and areas at risk.
