Question: Main Line of Public Works and Sacramento Deep Water Ship Channel, are in the United States?

<P0-S0> The Main Line of Public Works was a package of legislation supporting a vision passed in 1826 — a collection of various long proposed canal and road projects that became a canal system (1824 proposals and studies) and later added railroads (amendments in 1828) designed to cross the breadth of Pennsylvania (mainly, southern) with the visionary goal of providing the best commercial means of transportation between Philadelphia and Pittsburgh. <P0-S1>  Built between 1826 and 1834 by the Commonwealth of Pennsylvania, it established the Pennsylvania Canal System, the Allegheny Portage Railroad, and the Pennsylvania Canal System administrated under a new Commission. <SEP> <P1-S0> The Susquehanna Canal of the Pennsylvania Canal System was funded and authorized as part of the 1826 Main Line of Public Works enabling act, and would later become the Susquehanna Division of the Pennsylvania Canal under the Pennsylvania Canal Commission. <P1-S1>  Constructed early on in America's brief canal age, it formed an integral segment of the water focused transportation system which cut Philadelphia-Pittsburgh (pre-railroad) travel time from nearly a month to just four days. <P1-S2>  One of the system's navigations, the Susquehanna Canal/division created a mule-towed navigable channel 41 mi along the west bank of the main stem of the Susquehanna River between a lock terminus near the mouth of the Juniata Tributary River and the canal basin at Northumberland. <P1-S3>  Meeting the West Branch Canal and the North Branch Canal at Northumberland, it formed a link between the public and private canals upriver and the main east–west Pennsylvania Canal route known as the Main Line of Public Works which was devised to connect Philadelphia to Pittsburgh, southern New York, northern Pennsylvania and Lake Erie using most of the far reaches of the Susquehanna's tributaries. <SEP> <P2-S0>  It was completed by the United States Army Corps of Engineers in 1963. <P2-S1>  The channel is about 30 feet (9 m) deep, 200 feet (61 m) wide and 43 miles (69 km) long. <P2-S2> The Sacramento Deep Water Ship Channel (also known as Sacramento River Deep Water Ship Channel or SRDWSC) is a canal from the Port of Sacramento in West Sacramento, California to the Sacramento River, which flows into San Francisco Bay. <SEP> <P3-S0> The AN/SQQ-32 Minehunting Sonar Set (MSS) is a variable-depth mine-hunting sonar system originally developed by Raytheon and Thales Underwater Systems (formerly Thomson Marconi Sonar) for the United States Navy. <P3-S1>  It includes two separate active sonar systems to detect and classify mine-like objects on the surface, in the volume, or on the bottom of the sea. <P3-S2>  The sonar systems are packaged in a single towed body tethered to the ship through a cable providing power and data transmission, with the cable length variable via an electric winch. <P3-S3>  A hole in the ship extending from the Sonar Maintenance Room (SMR) to the hull allows movement of the towed body in different configurations for maintenance, stowage at sea, and minehunting operations. <P3-S4>  The towed body can be configured for minehunting by either locking to the bottom of the ship’s hull for shallow water operations, or by extending and retracting the tow cable to allow for variable depth sonar (VDS) operations. <P3-S5>  VDS operations are necessary in deep water due to refraction of the sonar from the various temperature layers present in the ocean; with the sonar positioned in the same thermal layer as the suspected mines the error induced by refraction is minimized. <P3-S6>  The detect and classify sonar subsystems are independently monitored and controlled by two operators at independent panels working together to find and characterize underwater objects as mine or non-mine like objects.
