This interesting report tabulates the results of flow $53.25: Dfl. 125 measurements and analysis of the River Rhine water, starting at Rekingen (Switzerland) and ending at Kampen, The main objective of this book is to explain the general Vresswijk and Gorinchem (Netherlands). About 1000 km principles underlying the environmental problems and the of main river are covered.
