eutrophication model relative error Boons Camp, Kentucky

Full-text · Article · Jan 2015 Alexey GudimovDong-Kyun KimJoelle D. Discrepancies between simulated and observed ammonium levels were mainly due to the explicitly modeled egestion of excess nitrogen during zooplankton feeding. The model reproduces the key epilimnetic and hypolimnetic temporal patterns of the system and results in a good fit between simulated and observed monthly values. There have been attempts to introduce more realistic complexity into lake models using stochastic [17] or neural network [18] methods, models that simultaneously simulate nutrient and plankton dynamics181920212223 , and some

This study suggests that properly simulating three-dimensional advection is important to properly predict the distribution of pollutants within some lakes and reservoirs and that this model may be directly applicable to Thomann, Richard P.

Our model also suggests that dreissenids filter a considerable amount of particulate P from the water column, but the effective clearance rate is significantly lower with a substantial amount of the The aim is to more tightly integrate the expert's knowledge and the evolutionary system through an iterated cycle of knowledge refinement and evolutionary search. We used parsimonious sub-models for the source/sink terms for temperature, dissolved oxygen, ammonia nitrogen, phosphorous, phytoplankton, and zooplankton concentrations and tested the model predictions against field measurements from the Chahnimeh Reservoir

Winfield, John J. In addition, we also assessed the model performance based on the relative error (RE), another error metric (Arhonditsis and Brett, 2005b). We found three seasonal components (modes of variability). The fate and distribution of these pollutants within lakes is difficult to predict.

The first component (January, May, November, December) is associated with the conditions that determine the abundance of the herbivorous cladocerans; the second component (June–September) coincides with the summer-stratified period, and the Results were notably poorer when the three-dimensionality of the model was removed. Levine, 1975. The model was forced by 1962 nutrient loadings, when the lake received large quantities of treated wastewater treatment effluent, and accurately predicted the phytoplankton community responses (phytoplankton biomass and cyanobacteria dominance)

This indicates that the relation between secondary production and nutrient recycling has significant effects on the fractionation of the major elements (C, N and P) and regulates their distribution between the Publisher conditions are provided by RoMEO.

We used Monte Carlo simulations to reproduce the meteorological forcing (air temperature, solar radiation, precipitation and subsequent river inflows) that in large part regulates phytoplankton interannual variability for the last 25 A.
