NOTICE TO USER'S OF LUMPED (20th October, 2005)
A bug in LUMPED code, that doubles the output concentration only in models with bypass flow discovered and fixed as of 20th October 2005.
All models were tested again for mass balance by using following approaches:
1. A single tracer impulse with a concentration (mass) magnitude of 10 was used as input. All models recover the injected tracer mass.
2. A continous tracer impulse series with a concentration (mass) magnitude of 10 used as input. All Models recover the injected tracer mass.
Executable form of fixed version (LUMPED 01.10.02) can be downloaded from the link below.
