Inland Water Mapping

Focus: Inland Water Mapping

Every month we will focus on a specific theme, featuring a selection of articles which have previously been published in Hydro International magazine. By including a mix of older and more recent articles, we will present a complete recap of the subject. Furthermore, we will be bringing you a bi-weekly round-up of ‘Focus Stories’ related to the theme through our newsletter (sign up here). The theme for September 2017 is:

Even when for inland water mapping the hydrographic techniques are familar, there are special requirements and challenges often due to the specific characteristics of inland survey and positioning. Often it's related to the reduced depth, accessibility or working space. This also creates opportunities to use techniques like airborne Lidar bathymetry or USVs.

Unmanned Mapping of Ultra-shallow Waters

Hydrographic surveying in ultra-shallow, inland and enclosed waters can prove extremely challenging and often presents increased risks and obstacles to both personnel and equipment. These considerations include health and safety issues, potential damage to equipment, lack of... (read more)

Changes to Data Sourcing in Modern Times

Seaports, waterways and climate are inextricably linked. Weather anomalies change bottom contours and destroy aids to navigation, compromising safety. In the past decade maritime applications, maturing marine technologies and crowdsourcing have given mariners access to near-... (read more)

IENCs in Flanders

Safety of navigation on inland waterways is as important as in maritime waters. To guarantee this, Electronic Navigational Charts (ENCs) have now been produced for several years. As inland waterways have specific features and regulations different from the maritime area, the... (read more)

Technology in Focus: Acoustic Doppler Current Profilers (ADCP)

Rather than a spinning propeller, the Acoustic Doppler Current Profiler (ADCP) – just like dolphins and bats – uses sound to explore its environment. Operating underwater, the method works like hand-held radars used by police to catch speeding motorists. This art... (read more)

Inland Water Mapping

Autonomous Vessel Delivers in Challenging Environment

The hydrographic survey industry is changing and moving away from manned operations in an effort to reduce costs and increase safety. During the Shallow Water Survey 2015 conference this new approach and the associated challenges were assessed by Swath Services during the co... (read more)

Crowdsourcing Enhances Navigation Awareness

In this internet age, crowdsourcing is fast providing practical contributions to our understanding of the world around us. Whether it be software developed in an open-source environment, inputs from ‘those in the know’ to create and maintain wiki pages, or the pr... (read more)

Reconnaissance Surveying using Satellite-derived Bathymetry

False Pass, AK, USA, is the eastern-most passage through the Aleutian Islands between the Bering Sea and the Pacific Ocean and provides a passage for small to mid-size vessels. The passage is considered an alternative route to Unimak Pass, AK for vessels from mainland Alaska... (read more)

ALB Operations, Standards, Specifications and Stuff

In his column in 'Hydro International', Mark Sinclair from Fugro writes that he commends the ‘Technology in Focus: Bathymetric Lidar’ article; it is right on the money. Amongst other things, it describes the crucial factors leading to a successful... (read more)

Hydrographic Surveying in the Port of London

By the end of this year, the gap will have finally closed on the mandatory requirements for ships to carry an Electronic Chart Display and Information System (ECDIS), with all existing vessels of over 10,000GT being required to be so equipped (all new vessels greater than 3,... (read more)

Inland Water Mapping

Riverbed Surveying

In order to meet the requirements of the European Water Framework Directive (EU-WFD), authorities face the problem of performing area-wide surveys of all kinds of inland waters repeatedly. Especially for mid-sized and small rivers, a traditional survey approach imposes almos... (read more)

Hydrography for Modern Water Management

Dry feet, sufficient clean water and reliable and useful information. That is what integrated water management means to Rijkswaterstaat in the Netherlands. All measures are planned around the users, nature and the landscape and are carried out in close cooperation with water... (read more)

Port of Rotterdam – Innovative Hydrography

The Port of Rotterdam is a leading global port and by far the largest seaport in Europe. The port is situated in the Rhine delta and with its direct connection to Europe’s largest industrial region, the Ruhr area, it is a key entry point to the European market. Underst... (read more)

Industry Brings Innovation to Inspire the New Generation

For the fifth year in a row, the Lake Survey was held in the Netherlands. This year Teledyne CARIS collaborated with Boskalis and Fugro in a one-week all-encompassing practical survey week. From 26 to 30 June 2017, 14 students worked with some of the most advanced equipment... (read more)

The WTI Field Measurement Programme

Numerical models are used to predict water levels, wave heights and wind fields under extreme storm conditions. This paper aims to give a short overview of the measurements of three field sites in The Netherlands. Validation material for these numerical models is obtained in... (read more)
