As a tribute to the great Ukrainian writer Vasili Grossman, author of the novel “Everything flows”, whose reading strongly recommend the authors to all young Spaniards, a reflection is elaborated on the incredible errors contained in the “renovated” Valencian instrument of hydrological planning level, obligatorily binding, known as “PATRICOVA”. The fact is that, strange as it may seem, this plan has a great deal of technical errors, that AUG-ARQUITECTOS SLP pointed out to the competent Valencian administration in 2013. But this was ignored and the plan was adopted without correcting any of the errors. To correct these will consume in the future a great deal of public resources. The picture illustrating the article is a nod to another of the Soviet grandmasters, namely, filmmaker Mikhail Kalatozov, director of the beautiful film “The Cranes Are Flying” (1957).
