ABSTRACT
The analysis and understanding of hydrological regimes occupies an important place in the hydrological cycle. Although the hydrological regime is not explicitly part of the water cycle process, it plays an integrating role in the sense that on the one hand, discharge is an integrating measurement of the conditions that generate surface runoff, and on the other hand the analysis of hydrological regimes is based on large data sets and requires a number of statistical tools. Thus, the hydrological regime can be viewed as a linking element between hydrological space and time, and supplies invaluable information for anyone interested in the behavior of a river or a region, whether it is for hydrological, geographical or climatic purposes. In this chapter we will cover some of the essential concepts, followed by some classification options and a description of specific regimes in our latitudes.
