Document Summary
Is a type of geological feature that results when a river periodically overflows its banks due to rainfall, snow melt ot other factors. In a temperate system, the overflow into a floodplain is relatively random or unpredictable in time: floodplains help filter water, help clean water and limit dead zones. In this tropical system, the rainfall is predictable seasonally. Stong wet monsoon period followed by a lengthy dry period (about 6 months each: many tropical floodplain lakes serves as major fisheries on the globe, often in developing countries, ex. Meandering streams/rivers and floodplains: floodplains are formed at the lower slopes, where meandering, or lateral movement occurs, in a river. Through time the meandering moves laterally creating a fertile plain. Floodplain extent defined under infrequent high flows events that drive erosion and form boundary. Note oxbow lakes: a remnant of a past configuration that was (cid:498)cut off(cid:499) from river. Floodplains sometimes have areas that have floodplain lakes (e. g. the great.
