Abstract

In the sense of “flowing water,” the term may also refer to the inflow of the tide. A flood is an overflow of water (or occasionally other fluids) that submerges dry land. The study of floods is part of the discipline of hydrology. Floods are a major issue in agriculture, civil engineering, and public health. Changes in waterway course or flood control measures like levees, as well as larger environmental issues like climate change and rising sea levels, all contribute to an increase in the intensity and frequency of flooding caused by human activity. Flooding can occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries, or it can occur as a result of an accumulation of rainwater on saturated ground in an area flood. Flooding can occur as a result of an overflow of water from water bodies, such as a river, lake, or ocean, in which the water although seasonal variations in precipitation and snow melt will affect the size of a lake or other body of water, these changes are unlikely to be significant unless they flood property or drown domestic animals.
