Abstract:
Artificial  Neural  Network  (ANN)  is  a  very  useful  data  modeling  tool  that  is  able  to capture  and  represent  complex  input  and  output  relationships.  The  advantage  of  ANN lies  in  its  ability  to  represent  both  linear  and  non-linear  relationships  and  in  its  ability to  learn  these  relationships  directly  from   the  data  being  modeled.  Modeling  of  rainfall runoff  relationship  is  important  in  view  of  the  many  uses  of  water  resources  such  as hydropower  generation,  irrigation,  water  supply  and  flood  control. 
This  study  is  to  purposefully  develop  a  rainfall  runoff  model  for  rainfall-runoff modeling  in  Sutlej  river  basin,  India  using  soft  computing  techniques  such  as Artificial  Neural  Network   (ANN),  Radial  Basis  Function (RBF)  and  Fuzzy  Logic. Training  and  simulation  was  done  using  Matlab 6.5.1   software  with  varying parameters  to  obtain  the  optimum  result.
