Need help with technical terminology? Our glossary provides clear definitions of key terms used in freshwater science and environmental research.
A structured scientific assessment of the physical, chemical, biological or economic factors affecting attainment of the uses of waterbodies. TALU assignments in the Ohio WQS have been derived using a UAA process.
An association of interacting populations of organisms in a given waterbody or habitat, e.g., the fish assemblage, benthic macroinvertebrate assemblage.
Streambed substrate refers to the type of substance on the bottom of the stream. The cQHEI and QHEI measure the size of the substrates (e.g., from fine sediment various sizes of gravels and cobbles, up to boulders). Both cQHEI include measure of smothering by sands and other fines and from siltation.
