Hydrology literally means the study of water. This involves measuring and observing everything from rainfall to the chemical makeup of rivers. Hydrology can then provide information on floods, droughts, drinking water, erosion, and weather modelling.

Water cycles have evolved over long periods of time to deal with environmental pressures. They are not, however, adapted to deal with new threats such as climate change, population growth, pollution and land-use change. It is difficult to tell just how these pressures will affect complex water systems and the biodiversity that relies on them.
