Linear Parameters 

 
Bifurcation Ratio (R_{b})  Rb = N_{u}/N_{u} + 1, where  [37]  
 N_{u} + 1 = no. of segments of the next higher order

 L_{u} + total stream length of all orders (km)  
 A = area of the watershed (km^{2})  
Stream Frequency(F_{u}) (no./km^{2})  F_{u} = N_{u}/A, where  [36]  
 N_{u} = total no. of steams of all orders  
 A = area of the basin(km^{2})  
Texture Ratio (T) (no./km^{2})  T = N_{u}/P, where  [36]  
 N_{u} = total no. of streams of all orders  
 P = perimeter (km)  
Length of Overland Flow (km) L_{o}  L_{o} = ½ Dd, where  [36]  
 D_{d} = drainage density
