Sometimes the river overflows its banks causing flood in the neighboring areas. They are fragile habitats vulnerable to time, tide, erosion, pollution and other effects from the land around them. They usually form in areas that are well sheltered, such as creeks, inlets and estuaries where fine sediments can be deposited. An estuary is defined as a partly enclosed body of water along the coast where one or more streams or rivers enter and mix freshwater with seawater. A quake is caused by the movement of the earths plates. The term estuary is derived from the Latin words aestus ("the tide") and aestuo ("boil"), indicating the effect generated when tidal flow and river flow meet. Salt marshes are exposed at low tide and at least partially flooded at high tide, so only salt . Erosion removes any interlocking spurs creating a wide flat area on either side of the river. Therefore both fresh water and salt water are found in the same vicinity. A stream with a steep gradient will tend to downcut faster than it causes lateral erosion resulting in a deep narrow channel with little or no floodplain at all.
