Harmful algae bloom in river or lake is an annual phenomenon in many countries. A simulation is a powerful tool that can provide spatiotemporal analysis of the algal bloom based on the comprehensive interpretation of complex water quality interactions. Meanwhile, deep learning-based water quality predictions show remarkable performance with dense sensor data, but they are only applicable to specific points where we can monitor at all times. In this paper, we propose a spatiotemporal algal bloom prediction model by taking advantage of both the water quality simulation and deep learning models. The EFDC(Environmental Fluid Dynamics Code) model generates water quality data for the study area by simulating the measured boundary data. Then, we utilize the generated water quality data for a CNN based learning algorithm to predict a Chl-a concentration. We prove that our approach provides reliable performance in terms of prediction accuracy of Chl-a concentration.
