Place Sediment in a cylinder Vt = A=πr^2 of sediment
Fill a cylinder with water and weigh = Wm Water mass
Add water slowly to sediment until saturated
Weigh remaining water = Wmr Water mass remaining
Subtract weight of Wm - Wmr =Vv (volume of water added to the sediment)
Divide Vv by Vt
Multiply by 100
Porosity as a %
