SNSIM is a computer program which can be used to formulate a steady-state, one dimensional, simulation model of a stream network. It is designed to evaluate and/or predict the dissolved oxygen, and the carbonaceous and nitrogenous BOD profiles in a river or stream where the effects of dispersion can be assumed to insignificant. The stream network consists of a river and its tributaries which are segmented into sections of constant hydrologic, physical, chemical and biological parameters.
