“…Each individual model is applied as it would be typically for a small temperate lake, and thus the configuration of the conceptual ecosystem is allowed to vary between models, reflecting how each of the three models has typically been applied in previous studies. DYRESM-CAEDYM (DYCD) is a one-dimensional ecological model consisting of two main components: a onedimensional hydrodynamic model (DYRESM: Dynamic Reservoir Simulation Model), which resolves vertical mixing and the resulting distribution of temperature, salinity and density in a lake/reservoir, and an aquatic ecosystem model (CAEDYM: Computational Aquatic Ecosystem Dynamics Model), which simulates a range of biological and chemical variables, such as inorganic and organic forms of phosphorus and nitrogen, up to seven phytoplankton groups/species and up to five zooplankton groups/species (Trolle et al, 2008). If a lake is characterized by a complex bathymetry, and higher spatial resolution is required due to the importance of horizontal circulation and transport processes, CAEDYM can also be run in three dimensions, by coupling to the Estuary, Lake and Coastal Ocean model (ELCOM, a 3-D-structured grid hydrodynamic model).…”

“…A comparison of these data with preliminary estimates of DI-TP indicated reasonable agreement between the two approaches (see Jennings et al 2008). The daily output from GWLF is also being used as input to DYRESM CAEDYM (Trolle et al 2008), a dynamically coupled model of in-lake physical, chemical and biological processes, to hindcast the biological responses of phytoplankton groups to past environmental pressures. A data set spanning 34 years of measurements is available for chlorophyll a from Lough Leane, allowing validation of both the palaeolimnological data and the hindcast model output.…”

“…In the case of Lake Rotorua (Rutherford et al [6]) calculated a time for near-complete equilibrium of sediments of up to 195 years, but noted quite rapid and substantial reductions in sediment nutrient releases, because of reduced levels of both nutrient loading and deoxygenation in the water column, with associated improvements in water quality. The lack of feedback between the water column and the bottom sediment composition in the current version of CAEDYM has been described previously, but has not been adequately accounted for in past lake model simulation efforts (Trolle et al [8]; Özkundakci et al [9]). …”

“…Several applications have been made of DYRESM-CAEDYM to different lakes (e.g. Burger et al [7]; Trolle et al [8]; Gal et al [13]; Özkundakci et al [9]) and these publications have detailed descriptions of the model equations.…”
