Sketch a simple conceptual model of Pine River Pond Sketch a simple conceptual model of Pine River Pond showing thelake, primary inputs, tributaries and removal mechanisms or storage.Build the Lake Load Management Model for Phosphorus for PineRiver PondUse the land allocation from the DES file. You will need tomatch NLCD land use (Links to an external site.) to categories in themodel.Use the Mean value in the model for coefficients, waterfowl andseptic loadsBriefly describe how the model works, and answer the followingquestions:• List land uses, and any discrepancies between NLCD andLLRM categories. Why did you select the LLRM category?What would you do if your region had a land use that wasnot listed in the LLRM template?• How would it change your results is you use the median,rather than mean?• Do you think the defaults for septic and waterfowl arereasonable? How could you get more accurate values forthese inputs?• What are the predicted concentrations from the model?How do they compare to the measured concentrations(from homework 6.• Are there inputs or sources that are missing from themodel?
