argine

Argine is a term used in civil engineering and hydrology to denote a raised barrier along the bank of a river, canal, or coastline. It can refer to an artificial structure built to contain or redirect floodwaters, or to a natural high bank that forms the edge of a watercourse. In English-language contexts, the closest equivalents are levee or embankment, while in Italian usage “argine” specifically connotes the defended edge of a waterway.

Construction and form vary with location and risk. An argine can be an earth embankment, often compacted and sometimes faced with stone or concrete for erosion resistance. It may include toe protection, drainage systems behind the barrier, and spillways or sluices to manage water levels. The design considers geotechnical properties, permeability, slope stability, and the need for maintenance access. In river systems, the argine is often paired with the opposite bank to define the channel and with associated floodplain management measures.

Terminology and usage. The terms destro and sinistro can designate the right and left banks of a river when facing downstream. Argini are central to flood defense, river navigation, and land use planning. They are distinct from dams or flood barriers that obstruct water flow across a channel; instead, argini line the watercourse to prevent overflow and stabilize banks.

Maintenance and risk. Argini require regular inspection for seepage, erosion, and plant overgrowth. Breaches or overtopping can occur during extreme flooding, necessitating emergency repairs and, in some cases, reinforcement or reconstruction. Environmental and climate-change considerations increasingly influence design and upkeep.
