	A Venetian canal, know to Venetians as a ''rio'', is a remnant of an ancient natural waterway. The [[canals]] today resemble their original appearance but have transformed slightly due to human intervention. A canal can be classified as an inner canal or and outer canal. An inner canal separates two [[~~Islands~~]] in the historic center of Venice, while an outer canal runs along the exterior of [[Islands]] in the lagoon. A canal may vary in size, shape, and number of intersections however its anatomy is typically consistent, as explained below.

A Venetian canal, know to Venetians as a ''rio'', is a remnant of an ancient natural waterway. The [[canals]] today resemble their original appearance but have transformed slightly due to human intervention. A canal can be classified as an inner canal or and outer canal. An inner canal separates two [[Islands]] in the historic center of Venice, while an outer canal runs along the exterior of [[Islands]] in the lagoon.

Every [[Canal]] is broken up into [[Canal Segments]] by intersections. For research and organizational purposes [[Canal Segments]] are given sub names originated from the [[Canal]] name.

== Coding ==
For information systems every [[Canal]] is given a code name to make identification easier. To identify individual segments the code name is given a number.

Example: ''Rio de la Panada'' is coded as PANA ; each of its 3 segments are coded as PANA1, PANA2, PANA3

== Anatomy ==
[[File:Canal_cross_section.png|400 px|right|thumb|Cross section of a Venetian Canal]]
The bed of a typical canal is composed of gravel, sand, silt, clay. A canal is bounded by two walls, a defined earth bottom, and any other bodies of water with which it may intersect. A [[Canal Wall]] is typically brick lined with clay or Istria stone which protects the foundation of buildings from becoming saturated with water. The bottom of the canal is defined by a layer of sediment. This sediment is composed of natural solids brought in from the ocean, as well as from sewage remnants and degradation from the bounding [[Canal Wall]]. When a canal is [[canal maintenance| Dredged]], the set depth of a canal is defined by how much distance there is from the [[Zero Reference Point]] to the layer of remaining sediment (''See [[canal maintenance|Digging Restrictions]]'').<ref> Ing. Lorrenzo Bottazo, November 2011 </ref>

==Canal Segmentation==
Over the centuries, all the [[canals]] of Venice acquired one or more names. Several canals have multiple names in common Venetian parlance, giving rise to confusion. Official names were never codified until the 1990's. For research and organizational purposes, every canal is broken into [[Canal Segments]]. A [[Canal Segment]] is created when a canal is intersected by another canal or by a [[Rio Tera]]. The canal will retain its name across intersections but each [[Canal Segment|Segment]] is assigned a specific segment code, based on the canal code, followed by a numeral, from north to south. For example [[Rio de la Panada]], which has code PANA, is broken into three segments, from north to south: [[PANA 1]], [[PANA 2]], and [[PANA 3]].<ref>"Venice and Its Lagoon".

==Canal Hydrodynamics==
The natural tides responsible for flushing out the [[Canals]] move sediment throughout the water ways. [[Sedimentation|Sediment]] build up occurs naturally as a result of this process.

==Canal Sedimentation==
Over time, sedimentation begins to build up in the bottom of canals and needs to be removed by [[Canal Maintenance]]

==Boat Traffic==
Boats traveling along a canal create wakes known as ''[[Moto Ondoso]]''. The constant [[boat traffic]] causes large wakes to hit the canal walls with great velocity. This can easily break off loose sediments of the walls and eat away at the stone as well as mortar. The deteriorating walls attribute to [[Sedimentation|Sediment]] build up in the [[Canals]].

==Sewage==
Industrial and household [[Sewage|Waste Water]] are discharged into the [[Canals]] and have minimal contributions to [[Sedimentation|Sediment]] build up.
