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.

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

The total potential was
developed at a high
water level regarding
flow characteristics,
berths, tons and traffic

Analysis tools (area based) for assessment and evaluation of trafficability of the potentials
Analysis tools allow for example the local computation of statistical parameters of single
sections of the waterway or special ship tracks and the determination of bottle-necks,
longitudinal or cross sections
