<P> A valley formed by flowing water , or river valley , is usually V - shaped . The exact shape will depend on the characteristics of the stream flowing through it . Rivers with steep gradients , as in mountain ranges , produce steep walls and a bottom . Shallower slopes may produce broader and gentler valleys . However , in the lowest stretch of a river , where it approaches its base level , it begins to deposit sediment and the valley bottom becomes a floodplain . </P>
