hi i am trying to model an instontaneous dam break problem using the st venant equations:(adsbygoogle = window.adsbygoogle || []).push({});

[h ; hu ] = [ hu ; hu^2 + 1/2gh^2] = [0; -ghbz] (where bz will equal zero)

i believe this is then the case

d(h)/dt + d(hu)/dx = 0

and

d(hu)/dt + d(hu^2 + 1/2gh^2)/dx = 0

however i have tried to program this, and unsuccesfully, using the lax wendroff two step scheme.

i have mad emyself completly confused over this and im hoping someone could just let me know any reference material or a few steps as to what i should be doing? thanks in advance Kyle

(ill post my code i have if needed)
