Description 211-222
Kabani river is
a 7th order stream with a basin area of 1647 km2. There
are 4 sixth order and11 fifth order sub-basins. This analysis is mainly
confined to 11 fifth order sub basins. Morphometric indices like stream
ordering, bifurcation ratio, stream length, drainage density, stream frequency,
form factor, elongation ratio, circularity ratio, constant of channel
maintenance, asymmetry factor, sinuosity index, length of overland flow,
drainage texture, relief ratio and relative relief have been worked out for all
these 11 fifth order sub basins. Factors considered for watershed
prioritisation are: bifurcation ratio, drainage density, stream frequency,
drainage texture, form factor, circularity ratio, elongation ratio and relative
relief. Sub watershed like Ws1, Ws3, Ws4, Ws10
and Ws11 showing low compound parameter are suggested for
conservation treatment.
