The numerical studies were carried out using a (nutrient-phytoplankton-zooplankton-detritus) biological model with a well-developed regeneration block. This paper presents the time-dependent vertical distributions of biological characteristics (concentrations nutrients, phytoplankton and zooplankton and benthic detritus pool) on the assumption that the horizontal distribution of these parameters is...
This paper presents a nutrient-phytoplankton-zooplankton-detritus biological model with a fully-developed regeneration mechanism with respect to the daily migration of zooplankton. The P-V-Z-D model consists of two partial differential equations of the diffusion type for the concentration of nutrients and phytoplankton, and two ordinary differential equations for the concentration of zooplankton and...
