• The nutrients are also added to the rivers and the lakes, They improve the health of fishes that can be consumed, There may be the relocation of fishes and the organisms living in the water bodies, The flooding may improve the ecosystem, New predators and prey are introduced to the areas, balancing the aquatic population.
• The floodplains are relatively flat lands adjacent to the body of water such as the river or the stream which become flooded (inundated with the water) when the channel capacity is exceeded, and the floodplain surrounding the river is used as agricultural land.
• The floodplains are dynamic natural systems, natural processes of periodic flooding, accompanied by the erosion and the deposition, They bring changes to the topography, the soils, the vegetation, and the physical features within these areas over time.
• The floodplains provide a wide range of benefits to the ecosystem and community that includes, The flood storage and erosion control provide a broad area with streams and rivers to spread out and accommodate temporary storage of the flood water, reducing the flood peaks and the erosion potential.

The flood offers groundwater recharge, It provides the habitat with a variety of fish and the wildlife including rare and endangered species, It offers biological productivity, They provide fertile soils with a high rate of plant growth and diversity, richer agricultural harvests, and healthier forests.
