Resum
Water is as scarce as it is necessary. Water availability in semiarid regions is often constrained by droughts. The study of droughts pertains to several scientific disciplines, including meteorology and hydrology. This paper presents a step-by-step description of the cumulative rainfall curve, a common technique for drought analysis. Students download historical rainfall data for the town where they live. Thereafter, they carry out a spreadsheet-based analysis to characterize drought from a historical perspective. Finally, a series of additional interpretation exercises are proposed. This exercise is appropriate for a wide range of age groups and courses.
