Transport time scales are often offered by scientists, and accepted by ecologists, as qualitative indicators of the susceptibility of ecological
components within an embayment. However, rigorous quantitative methods were never presented to confirm this intuition. Transport time scales
in water bodies are classically based on their physical and chemical aspects rather than their ecological and biological character. The direct
connection between a physical time scale and an ecological effect has to be investigated in order to quantitatively relate a transport time scale
to ecology. This concept is presented here with some general guidelines and clarifying examples. To be able to relate physical time scales to
biological processes, a simple tidal prism model is developed that calculates temporal changes in concentration and the related exposure.
This approach provides a quick method to calculate the characteristic time for transport in a large number of embayments, which can also
help in classification endeavors.
