Mangroves provide natural filtration, habitat, and prevent erosion into the surrounding marine environment.

The city's water has never been filtered artificially because of natural filtration in the watershed areas around the reservoirs.

Development would not only remove the natural filtration provided by Sterling Forest, but also contribute additionalcontamination to the water supply.

Any stochastic process X is an adapted process with respect to its natural filtration.

Instead, there are usually terms which come with a natural filtration .

A stochastic process is always adapted to its natural filtration.

This mechanically enhanced natural filtration produces clear, clean water.

Suppose that is a stochastic process on a probability space with natural filtration .

Let be the natural filtration of by the Brownian motion :

The water is clear due to the lack of pollution and the natural filtration of the water through many sand dunes.
