How to make an estimation of the siliciclastic sediment supply, expressed in sq. m/ky?
A. The sediment volume used by PHIL E is the value that is required to fill the area plus material that is lost at the margins by gravity-flow processes. If you measure the decompacted thickness of a layer at discrete points and multiply that thickness by the distance between the each point you will end up with an area for the cross-section. These units will probably be square meters. Divide the value by the duration (in ky) over which the sediment was deposited to determine the influx rate. These units will be square meters/ky. The actual volume that PHIL E requires will be greater than this value if any gravity-flow sedimentation is occuring on the front of the clinoform. Therefore you will almost always need to increase this influx rate. It is always good try to adjust the position of the coastline through time by adjusting the sediment supply. If you are satisfied the thicknesses are correct (controlled by subsidence rates), increase the influx rate if the system did not prograde f
