There are many differences exists between waterfall model and spiral model. In waterfall model if any sudden change takes place in the project, then its very hard to fix the issue. Wherein spiral model we can change according to our requirement.

spiral model is iterative model hence its easy to implement it .
piral Model is called meta model because it is composed of several other models.For example a single loop spiral actually represent the Waterfall Model.The spiral model uses prototyping approach before embarking on the actual product development effort.Also the spiral model can be considered as supporting the evolutionary model-the iterations along the spiral can be considered as evolutionary levels through which the complete system is built.This enables the developer to understand and resolve the risks at each evolutionary level.The spiral model uses prototyping as a risk reduction mechanism and also retain the systematic step approach of waterfall model.(
Modified waterfall model verified and validate the user requirements for every phase. Meanwhile, waterfall did not, it only verify and validate user requirement at the end of the phase.
The RAD model, also known as the Rapid Application Development, is a linear software for creating prototypes. The Waterfall model is a sequential software.
