File:Flooding in Southern Spain.gif

English: Both these images use a combination of infra-red and visible light to increase the contrast between water and land. Vegetation appears bright green. Clouds appear skyblue. Water ranges in colour from electric blue to navy. Bare ground appears tan. Much of the flooding in the province of Seville occurred along the Guadalquivir River, which flows past the city of Sevilla en route to the Golfo de Cádiz. Before emptying into the gulf, the river feeds wetlands along the coast, and the most conspicuous difference between the images is the soggier appearance of these wetlands. Whereas patches of bright green cluster around discrete water bodies in the old image, electric blue—suggestive of standing water—surrounds the deeper water bodies afterwards. Away from the wetlands, in the direction of Costa del Sol, several water bodies appear swollen. Overall, the landscape appears greener in the later image, indicating that greater precipitation spurred plant growth in the normally arid region.
