Drainage area and river mileage of Nebraska streams part I

The value of stream discharge data for hydrologic studies is enhanced by the availability of accurate information on size of area drained, distance between selected sites along stream course, and hydraulic gradients. Information on the location of cultural and natural features that affect streamflow also is valuable for hydrologic studies, particularly those that involve engineering considerations. Although stream-discharge data have been collected for many years and at many points, relatively little accurate information on the physical features of the areas drained has been compiled. In the past, such information was compiled only when occasion demanded, and owing to a general lack of detailed topographic maps, many of the values obtained were not precise by present-day standards.
