Today: water level's gone down! this measuring stick refers to NAP, Normaal Amsterdams Peil, which is the referenceheight to which heightmeasurements are related in the Netherlands. Simply said NAP more or less equals average sealevel. However I can't make out how this measuring stick compares to the NAP, because there is no '-' or '+' sign above the numbers in the blue here; does it mean the waterlevel's 90 cm above NAP or what, will investigate further - have not yet found an answer on internet; I'm hoping the guy who works for the pumping-station will visit one of these days, he'll probably know more. |
