The Chicago Area Waterway System (CAWS) is a complex of natural and artificial waterways extending through much of the Chicago metropolitan area, covering approximately 87 miles altogether. It straddles the Chicago Portage and is the sole navigable inland link between the Great Lakes and the Mississippi River and makes up the northern end of ...
A piper diagram and two ternary diagrams on the composition of intrusive volcanic rocks; see QAPF diagram. A Piper diagram is a graphic procedure proposed by Arthur M. Piper in 1944 for presenting water chemistry data to help in understanding the sources of the dissolved constituent salts in water. This procedure is based on the premise that ...
The Illinois Waterway system consists of 336 miles (541 km) of navigable water from the mouth of the Calumet River at Chicago to the mouth of the Illinois River at Grafton, Illinois. Based primarily on the Illinois River , it is a system of rivers, lakes, and canals that provide a commercial shipping connection from the Great Lakes to the Gulf ...
The Chicago Harbor Lock, also known as the Chicago River & Harbor Controlling Works, is a stop lock and dam located within the Chicago Harbor in Chicago, Illinois at the mouth of the Chicago River. It is a component of the Chicago Area Waterway System , and is used to control water diversion from Lake Michigan into the river and for navigation.
Stiff diagrams can be used: 1) to help visualize ionically related waters from which a flow path can be determined, or; 2) if the flow path is known, to show how the ionic composition of a water body changes over space and/or time. Example of a Stiff diagram. A typical Stiff diagram is shown in the figure (right).
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...
Diagram depicting construction of the lake tunnel to connect the Two-Mile Crib to onshore water works. The Two-Mile Crib was constructed as part of a scheme by Ellis S. Chesbrough in 1865, to help with the purification of the water because of damage caused by the city dumping sewage into the lake. Construction of the crib began in May 1864 ...
