In the design and calculation of stormwater drainage systems, the design rainfall intensity plays a crucial role and is widely used in runoff calculations. Due to the influence of local climatic factors, the selection of probability distributions for rainfall frequency analysis and the methods used to determine parameters for empirical equations result in a variety of equations compared to traditional Rainfall Intensity-Duration-Frequency curves.

Photoelasticity images of pulsed laser ablation in water and in air were simulated by Finite Element Method. In the paper "Compare transient stress induced in in-air and in-water laser ablation using simulation method", the Von Mises stress distribution in the target is deduced from the simulated images and is compared between the two-ablation regimes. The result confirms that pulse laser ablation in the water can induced a stress about 100 times higher than that induced in ablation in the air.
