Hydrometry. Slope-area method has-digital BS 6440:2011 provides guidance andWhat is ISO 1070 Slope area method about? ISO 1070 is an international standard that discusses the attributes of hydrometry. ISO 1070 specifies a method of determining discharge in open channels from observations of the surface slope and cross sectional area of the channel. ISO 1070 is applicable to use under special conditions when direct measurement of discharge by typically more accurate methods, such as the velocity area method, is not possible.
