This study develops a whole new aspect of contingent-claim model for hedging the catastrophe risk. We describe the framework of the new hedging strategy - catastrophe swap - as detail as possible and compute the exchange amount of CAT swap contract by Monte Carlo Simulation. Last but not least, this article reveals the most powerful back-up, net cash flow and utility comparison between different strategies, to prove the practicability and favorableness of our catastrophe swap model.

By the analysis of dive and horizontal plane nonlinear model, the catastrophe model on de dive plane is deduced, and catastrophe stability is analysized. In the horizontal plane, simplified equation is gained by center manifold theory, then draws the conclusion that the stability of limit circle arises from critical point is relate to small difference of move point and critical point.

Firstly, based on the force acting on a single-particle, establish a discriminant formula of the sand threshold, and prove that the sand threshold belongs to the cusp catastrophe. Then establish the basic equation of the cusp catastrophe using coordinate transformation and catastrophe theory. Finally, while particle Reynold number and equivalend diameter are the state variables and Shields parameter is the control variables, we can obtain the model of cusp catastrophe of sand threshold, putting those variables into the basic equations of the cusp catastrophe. The model is derived from the mathematics, which has a certain mathematical theory foundation.
