What’s Missing?
• Data to assign G1, G2, G3 splits to loads.• Right now, splits are assigned to keep the amounts of reactive material
similar to previous (2010) calibration.• Laboratory studies are underway to examine reactivity of material in
Conowingo sediments. Available sometime in 2016.• Model studies are proposed to improve predictions of reactivity of loads
at Conowingo spillway. Available March 2016?• Laboratory studies are proposed to examine reactivity of eroding wetlands
material. Available December 2016?• We may have to individually calibrate G2, G3 properties (e.g. settling
rates) to adjust model to new loads, other factors. • Revisions to PIP calibration and parameterization may be warranted.

Chesapeake Bay Tidal Wetlands
• Extent from National Wetlands Inventory.
• Determined largely from vegetation perceived via aerial photography.
• 190,000 hectares of estuarine (green) and tidal fresh (red) wetlands.
• Shape files provided by Quentin Stubbs and Peter Claggett, EPA Chesapeake Bay Program.

Assign Wetlands Areas to Model Cells
1. Wetlands polygon.2. Divide polygon into
“fishnet.”3. Overlay 10-digit
HUC boundaries.4. Assign wetlands
areas to model cells based on proximity and local watershed boundaries.
5. Thank you, Scott Bourne, ERDC.

Wetlands Module
• We don’t want to develop a complete wetlands biogeochemical model.
• We do want to develop a simplified module that includes:– Particle burial (organic and inorganic)
– Respiration
– Denitrification
– Primary production?
– Others?

This applies to all particles, organic and inorganic.

Where Are We Now?
• Particle settling at one tenth the rate through water column.
• Respiration of 1 gm / sq m / d with temperature correction.
• Compared to:
– No wetlands particle burial
– Respiration of 3 g /sq m / d, temperature corrected but areas provided for TMDL model.

What’s Missing?
• Present oyster biomass and distribution.
• Information on aquaculture (location, methods, harvest).
• Incorporation into present model.
• The 2005 oyster model is operational in the present model.
• We could make projections similar to the effects of a ten-fold biomass increase, using previous biomass estimates.
• Time to obtain more recent information is open-ended.

WQSTM Shallow-Water Simulation
• We received the shallow-water database from CBP circa autumn 2012.
• These are grab samples and measures collected when continuous stations are serviced and coincident with Dataflow cruises.
• More than 750,000 records.
• Roughly 84,000 useful observations.

We’re in reasonable agreement with physical quantities such as temperature, salinity, dissolved oxygen.

Overall, we tend to be low on chlorophyll, TSS, high on dissolved oxygen.
