Dynamics of a lake-eutrophication model with nontransient/transient impulsive dredging and pulse inputting

In this work, we present a lake-eutrophication model with nontransient/transient impulsive dredging and pulse inputting. We obtain globally asymptotically stable conditions for the phytoplankton-extinction periodic solution of system ( 2.1 ). Furthermore, we gain the permanent conditions for system ( 2.1 ). Finally, we employ computer simulations to illustrate the results. Our results indicate the effective controlling strategy for water resource management.
