Input data can be from single beam, multibeam or multiple transducer surveys. The TIN MODEL program of HYPACK® can be used to compute several types of volume quantities. Additionally, the beach volumes supports beach replenishment projects. CROSS SECTION AND VOLUMES can read hundreds of sections, compute the volumes and send all of the sections to the printer/plotter in a matter of seconds. Over 20 methods are available to compute the area and volume of material for each profile segment (left slope, main channel, right slope), it can compute quantities for a single survey versus the design template, or for a pre-dredge versus an after-dredge comparison. The program is the de facto standard for volume computations by several national survey agencies. The CROSS SECTIONS AND VOLUMES program quickly computes volume quantities for cross sectional profile lines compared to the channel design template and channel overdepth template for each line. It can compute volume quantities either from sections across channels or from surface models (TIN MODEL). The HYPACK® ability to compute volume quantities is unsurpassed.
