River Navigation Assessment | Dipl.-Ing. Dennis Harlacher

|

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


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.

Assessment procedure RiNA:

Components and structure

22.08.2016

|

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

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
