About the Project


The overall objective of the WEIN project is the development of a monitoring- and information system to improve water use efficiency considering environmental, socio-economic and institutional factors adapted to the needs of water users and other stakeholders. To appropriately manage the scarce water resources during dry periods, the accessibility to high resolution time series on climate and runoff is indispensable.
The project combines up to date methods for quantifying and monitoring water availability with the implementation of a web based water resources information system for a more efficient irrigation management on basin and on irrigation scheme scale. The consortium pursues the following detailed objectives:


  • To elaborate a Limarí state of the basin report based on all available data (applicable to other catchments) considering the physical environment, socioeconomic and institutional aspects as a basis for public and private stakeholders and research institutions
  • To develop site-appropriate climate monitoring technologies and install pilot stations to provide knowledge on high elevation climate parameters
  • To develop site-appropriate discharge monitoring technologies and install pilot stations in irrigation scheme in order to detect losses and improve transparency
  • To improve the data storage and presentation of hydro-meteorological and geo data as well as other information in a web based River Basin Information System
  • To develop an information management system for an efficient water distribution for the irrigation management associations
  • To establish a wide ranging network of public and private water sector institutions interested in water resources and drought management
  • To elaborate site appropriate drought indices: Based on data analysis and hydrological modeling, drought indicators will be defined and aggregated to indices in order to be able to establish a drought monitoring and alert system
  • To understand the role of climate variability for the hydrology in semiarid mountainous Northern Central Chile
  • To establish whether significant changes in the hydrology of the Limarí basin are likely to result from climate change
  • To establish whether such changes will have implications for land use and hence socioeconomic development of the local human population.
