  3. 3. |  The trafficability of inland waterways can be analysed by a suitable combination of nautical relevant information from several disciplines Aims of the assessment procedure RiNA River Navigation Assessment | Dipl.-Ing. Dennis Harlacher  The surface visualisation of the trafficability is based on different, interdisciplinary input data, such as - geometric properties of the river and several variants concerning the hydraulic model, respectively, - hydraulic parameters of a multidimensional CFD-model, - parameters of inland waterway vessels or requirements concerning the fairway and - objects from the Inland Electronic Navigational Charts, optionally with additional information. 22.08.2016 Page 3

  5. 5. |  Constant, graded (distance based) and multistep procedures can be chosen for the single potential development  Generation of single potentials for the different specialised fields in consideration of - Flow Parameters (e. g. water depth and flow velocities) - Parameters of inland waterway vessels or special requirements concerning the fairway (e.g. minimum depth, velocity limit, driving direction) - Objects of the Inland ENC (e. g. fairway, buoys, berths) and additional information (e. g. driving rules)  A safety clearance (e. g. around a bridge pier, etc.) can be defined for each object  Transform of single potentials to total potentials by suitable combination and weighting Assessment procedure RiNA: Potential development River Navigation Assessment | Dipl.-Ing.
