etween thegage height and the cross sectional area of the stream. Prom these curveit is seen that the discharge ,mean velocity and the sectional area isa function of the gage heights. Since the discharge is the product ofthe tv;o factors area and velocity,and since a change in either vrillproduce a corresponding change in the discharge,the curves are plottedin order to study each independently of the other. The area curve is found by taking soundings at the section inthe river,that is being studied,and these should extend as far as thehigh water mark. The form of the velocity curve depends on such things as the slopeof the river and the roughness of the bed. It may be either concave orconvex to the axis,and in some cases is a straight line. It is also poss-ible to have a combination of the thr-^e conditions. The slope of theriver as given out by the goverment and other data that is necessary inthe calculation for the discharge is as follov--s; niope 1 : 8*^000 H3-drauIic radius 12..30
