9 Horton’s Basin Laws N x+1 = hn N x stream numbers L x+1 = hl L x stream lengths S x+1 = hs S x stream slopes DA x+1 = ha DA x (Drain area;Schumm 1956) [ linearized forms ] ln N =  +  SO; where exp(  is hn ln L =  +  SO; where exp(  is hl ln S =  +  SO; where exp(  is hs ln DA =  +  SO; where exp(  is ha Network adjustment (Horton 1945)

10 Horton’s Basin Laws -related concepts- bifurcation ratio = 1 / hn constant of channel maintenace = intercept on log-log plot of L vs log A drainage density =  L/ Area ( units: l/l 2 ) =  (N i * L i ) / total area area Total length of channels intercept Network adjustment
