Financial support for water conservancy construction is an important approach to promote the development of water conservancy economy. In order to deal with numerical solution for stock option in water conservancy finance, a hybrid optimization algorithm is proposed. By virtue of the relation between Black-Scholes model and heat equation, a class of heat equations with initial-boundary values is established based on Schwarz waveform relaxation algorithm, meanwhile particle swarm optimization algorithm is applied to estimate parameters in option pricing model. In numerical experiments, the hybrid optimization algorithm is used to seek the approximate value of call option based on water concept stock, and it obtains better estimation results than existed methods.
