<br/><br/> Dam  is  a  very  essential  part  of  our  society.  It  provides  power  supply,  irrigation  water,  tourism,  navigation  and  many  other  benefits.  Dam  structure  is  very <br/>crucial and lack of strategy, maintenance, structure design can cause high level of flood devastation to the adjacent area. It affects at high level interms of loss <br/>e,  loss  of  economy,  environment  degradation  etc.  Dam  breach  process  may  be  instantaneous  or  gradual,  depend<br/>paper  hypothetical  breach  of  earthen  dam  has  been  analysed  by  using  HEC-RAS,  which  is  a  computer  program  and  used  for  dam  breach  modelling. <br/>Methodology adopted during modelling is summarised in this paper. Dam breach analysis is important, it provides detail knowle<br/>e  elevation  values  and  also  about  inundated  areas  by  using  inundation  maps.  These  maps  are  useful  for<br/>administration and other stakeholders at the time of emergency, so that local people can be saved by providing emergency warn<br/>show that overtopping failure causes  more  flood with  respect  to  piping  failure  in earthen dam, however  the  difference is  meag<br/>study based on limited data of Baur dam (Uttarakhand) analysed using HEC-RAS modelling breach guidelines. The results of HEC<br/>worst scenario is pool reservoir level with overtopping failure pattern of Baur dam.
