The value of water evaporation is a key data in establishing the water balance of lakes and reservoir dams. In general, the evaporation of water bodies is assessed either from observation data from evaporation pan (Colorado pan and class A pan), or by ana... see more
In a circular conduit of diameter D and of a given slope S0, two critical states of the flow may occur for two different discharges. The first one is observed at shallow depths while the second one settles down at greater depths. This statement is the res... see more
