Definitely need to know algebra. You will need to study calculus and differential equations to get a degree in hydrology and to understand the fundamental equations governing hydrological process. But, in practice, most hydrologists rarely, if ever, solve differential equations themselves. read more
Math is very important for hydrology. Especially for surface water problems, you require understanding of differential equations while open-water hydraulics like backwater calculations are complex. If you need a great deal of detail, these problems cannot be solved analytical, only numerical. read more
Hydrology has evolved as a science in response to the need to understand the complex water system of the earth and help solve water problems. This hydrology primer gives you information about water on Earth and humans' involvement and use of water. read more
