|| Filters are essential in the design of embankments/dams, drains and wells for water and oil supplies. As
a result of these functions, filter use is increasing. In order to use the required filter, various empirical relations
have been given based on mathematical and field experience. However, these guidelines have not
worked to perfection considering the fact that clogging within the filter face is a serious challenge. A
short review on filter design criteria is given in this script coupled with a numerical formulation to propose
the design limits.
