Evaluation of the morphometric parameters requires preparation of drainage map, contour map, ordering of the various streams and measurements of catchment area, perimeter, relative relief, relief ratio, length of drainage channels, drainage density, drainage frequency, bifurcation ratio, texture ratio, circulatory ratio and constant channel maintenance, which help to understand the nature of the d

Net primary production (NPP) in the Yellow River Basin, China, during 1982-1999 was estimated with the CASA model using satellite data. The yearly NPP (NPPt) tended to increase during 1982-1999 throughout the Yellow River Basin. A large mean annual NPP for each grid cell was indicated in both the upper and lower reaches, and a low value was indicated in the middle reaches.
