Nationwide GIS-based regular gridded hydrological water budget – BIGBANG: methodology and estimates. Report on the state of the renewable freshwater resources
In the framework of its activity on national operational hydrology, the Italian National Institute for Environmental Protection and Research has developed a distributed water budget model named BIGBANG – Bilancio Idrologico GIS Based a scala Nazionale su Griglia regolare, aimed at evaluating the hydrological water budget components at monthly scale.
The report presents data and methods used in the BIGBANG model, as well as hydrological evaluations, trends and statistics obtained for Italy with the BIGBANG in the period 1951–2019. The aim of the document is to define an homogeneous hydrological context at national level to improve the knowledge on the state of the renewable freshwater resources.
