Water Accounting Plus

Welcome to Water Accounting at IHE Delft

NEW! MOOC now available:"Python for Geospatial analyses using WaPOR data". More information here or go directly to the course.

More News! On 5 July 2024, we concluded our short course on 'Remote sensing for Agricultural Water Management'. Read more about it here. Interested in learning how to create your own high resolution data on water consumption (evapotranspiration) and biomass production using pyWaPOR? Join us next year! More information here.

Independent estimates of water flows, fluxes, stocks, consumption and services

A systematic study of current status and trends in water availability and consumption in specified domains. Water accounting is defined as the systematic acquisition, analysis and communication of information relating to stocks, flows, and fluxes of water (from source to sinks) in natural, disturbed or heavily engineered environments (FAO, 2016)


A framework for communicating the state of water resources

The current website provides the framework and results of a new Water Accounting methodology (WA+) that is based on global-scale public-domain datasets. Its objective is to strive to achieve equitable and transparent water governance for all users and a sustainable water balance.

Essential information for the water sector 

WA+ provides independent estimates of water flows, fluxes, stocks, consumption and services, that in the near-future becomes certified. It is a multi-institutional effort from international knowledge centers (IHE Delft, IWMI, FAO, and WWAP) that are neither politically nor geographically connected to a given river basin.

Projects of international relevance

The use of the WA+ framework has been implemented in several basins across the world. The WA+ framework allows stakeholders to make informed decisions and support local water management practices.
