As a result, these ecosystems are fragmented, resulting in Transportation and trash disposal have negative consequences as The flood pulse attracts opportunists (such as birds). Floodplain trees, for example, are fast-growing and ![]() This enables them to benefit from changing floodplain The floodplains have high yearly growth and death rates, whichĪllows extensive parts of the floodplain to be colonized quickly. The riverbanks dry out and terrestrial plants grow to sustain the As theįloodwaters recede, microorganisms thrive in the littoral, while Water level, fish must develop swiftly during the flood. The river (the zone closest to the river bank) provides an excellent Fish spawning season generally coincides with theĬommencement of flooding because the flooded littoral zone of Supplemented by the breakdown of terrestrial plants drowned byįloodwaters. ![]() Nutrients are released from the dry soil. The flood pulseĪssociated with annual floods is the most characteristic aspect ofįloodplains from an ecological standpoint, hence the floodplainĮcosystem is defined as the area of the river valley that isįloods bring in nutrient-rich detritus and, as the soil is wet, Some of the most species-rich environments. Marked by significant spatial and temporal variety, resulting in Its floodplain when the rate at which it is cutting downwardsīecomes large enough that overbank flows become infrequent,Īnd portions of the abandoned floodplain may be retained asįloodplain ecosystems are diverse and productive. The river is considered to have abandoned Sediments as they travel from their source to their finalĭepositional habitat. As a result, floodplains serve as key storage sites for The amount of silt in aįloodplain far outnumbers the amount of sediment carried by rivers.
