With recent advances in computer technology, long term (one year) simulation of complicated estuaries with large-scale multi-dimensional (3D) numerical models has become possible. However, these numerical solutions still require the use of substantial (up to several weeks) supercomputer central processing unit time. An alternative method capable of analyzing changes at individual points in an estuary, as opposed to the global solutions generated by the numerical models, is desirable. This alternative method must also have the characteristics of being run in a short period of time. A system response approach which uses the input/output relationships from the numerical model to describe the dynamic behavior of tidal hydrodynamic phenomena can be used to play this role. The system response functions from a numerical model verified for a particular location can be used to simulate the resulting output function, such as change in salinity, when input forcing functions, such as tidal variation and freshwater inflow, change.
