| Definitionskos:definition | The HY_ChannelNetwork feature type specializes the HY_HydroNetwork realization defined in the Hydro Feature core model, specifically as an aggregate of surface depressions and surface channels which continuously or periodically contain water, without imposing a particular drainage pattern. This allows representation of the network, even if logically connected features are not connected at the representation level. If the realized catchment is connected with other catchments via hydro nexuses, the channel network is considered connected to the channel network realizing these catchments. HY_ChannelNetwork has surfaceDepression and surfaceChannel associations, and carries a drainagePattern attribute; it inherits through generalization the shape attribute, the realizedCatchment association as well as flowpath, catchmentDivide and catchmentArea associations. Depending on the application, the channel network and the related features may be described by suitable attributes. A channel-flowpath constraint is defined to support the recognition of the channel as flowpath realizing the catchment. |
