. DMS : Diagnostic Modeling System. Sedimentation and deposition; Channels (Hydraulic engineering). This power function describes the existing situation whereby the increasing sediment shoaling or dredging volume will require increased O&M cost with time. Figure 12 indicates how the segments after the intersection (sta 15+000 - 21+000) with the GIWW have cumulatively yielded larger amounts of material dredged. Figure 13 breaks down the cumulative volume dredged for maintenance from the GIWW into sections for the years in which most of the dredging has been performed. The years between 1986

Figure 13 breaks down the cumulative volume dredged for maintenance from the GIWW into sections for the years in which most of the dredging has been performed. The years between 1986 and 1995 experienced the most dredging activity. This observation is consistent with the increase in dredging frequency and cost noted by the Galveston District. +06.
