The Contour Interval of the above map us 20 Units. 750m. Gradient: Stream gradient can also be determined from a topographic As a contour approaches a stream, canyon, or drainage area, the contour lines turn upstream. Stream channels radiate outwards like wheel spokes from a high point. For small contour interval, the money required will also more as the field and office work will be more.
