Kanalplan

Kanalplan is a planning document or map that depicts a network of canals and related channels, including their routes and hydraulic structures, as well as associated land use and rights-of-way. The term is used in Danish and some Scandinavian contexts, but the concept is common in hydrological and civil engineering planning.

Purpose and use

A kanalplan supports design, construction, operation, and maintenance of canal networks. It also informs navigation planning, flood management, irrigation schemes, and environmental planning. The plan serves as a reference for planners, engineers, operators, and regulators throughout project lifecycles.

Content and components

A kanalplan typically shows the alignment of canals, channels, branches, and their dredged depths or bottom elevations, cross-sections, bank lines, and embankments. It includes water control structures such as sluices, locks, gates, pumping stations, junctions, culverts, and bridges, as well as water level indicators. The document may also display property boundaries, easements, land-use designations, and regulatory constraints. Data sources include land surveys, LiDAR, hydrographic surveys, bathymetry, and historical records. Formats commonly used are GIS layers and CAD drawings, often integrated with hydraulic models.

Process

Creating a kanalplan involves data collection, field surveying, hydrological and hydraulic analysis, adherence to design standards, stakeholder consultation, and formal permitting or approvals before implementation.

Applications and scope

Kanalplan is used in urban water management, irrigation districts, port and canal authorities, historic restoration projects, and environmental planning. It supports maintenance planning, dredging campaigns, water level management, and infrastructure investment decisions. See also: waterway planning, GIS, hydraulic modeling.
