Some environmental effects of flooding in the Niger Delta region of Nigeria was reviewed to provide the
desired knowledge needed for the effective management of flooding. Floods are caused by many factors: Heavy
rainfall, highly accelerated snowmelt, severe winds over water, unusual high tide, tsunamis, or failure of dams,
levees, retention ponds, or other structures that retained the water. Flooding can be exacerbated by increased
amounts of impervious surface or by other natural hazards such as wildfires, which reduce the supply of vegetation
that can absorb rainfall. The effects of flooding from the sources outlined above are felt by various 'receptors'. These
include, people, buildings, infrastructure, agriculture, open recreational space and the natural world. Flood warning
is the provision of advance warning of conditions that are likely to cause flooding to property and a potential risk to
life. The main purpose of flood warning is to save life by allowing people, support and emergency services time to
prepare for flooding. The secondary purpose is to reduce the effects and damage of flooding. Floods renew wetland
areas which in turn host a wide range of flora and fauna. Preventing flood waters from entering such wetland areas
will create imbalance to the natural state of things resulting to destruction of natural habitats and even extinction of
various species of animals and plants. Floods play an important part in various ecosystems. Humans, therefore,
should be careful when they try to prevent or control floods. Oftentimes, human intervention causes more harm than
good. The study discuses the meaning of flooding, basic background of the Niger Delta causes of flooding, types of
flooding, factors determining the effect of flooding, the effects o flooding, benefits of flooding and control of
flooding with emphasis on some countries to provide the desired knowledge needed for the effective management of
flooding in the Niger Delta region of Nigeria.
Key words: Affecting factors , causes, economic benefits and control, flooding , types, ,
