Development and update of water level and discharge rating curves for the Mekong mainstream

This technical note is an update of analysis of the rating curves for mainstream and tributaries of the Mekong River for 2009-2012, published in 2013, discussing the approach and methodology of rating curve establishment. The current publication underscores the Mekong River Commission Secretariat’s (MRCS) commitment to advancing integrated data management. The MRCS adopts the Time Series Management Software, AQUARIUS, to migrate rating curve development. This shift aims to establish a centralised, easily maintainable system, ensuring a reliable source of accurate water data. The transition of rating curve development to AQUARIUS is anticipated to enhance the efficiency, accuracy, and defensibility of water data management processes.
