4. FlowWest – Review of LSRWA
Purpose of Expert –
Review modeling analyses performed for the LSWRA.
Ensure that the appropriate input data and assumptions were used
Offer professional opinions on additional or revised modeling analyses that should have been performed.
Conclusions –
LSRWA depended on a “daisy chain” of models that passed outputs successively from one model to another.
Predicted sediment quantities were lower than the best available estimates or actual measured data suggested
Underrepresentation of potential sediment impacts (and in turn likely nutrient impacts) on the Chesapeake Bay.
