This page links to a physically unremarkable Soviet slide rule used for calculating things like the volumetric flow rate in irrigation canals used in Uzbek SSR for growing cotton, their primary cash crop [1].

Unfortunately, there are no scales on it for "evaporation" and "shitty construction", or the Aral Sea[2] might still be there.
