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.

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)

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)

Integrating UAS and Multibeam Echosounder Data

Knowing the volume of material present in a gravel quarry can make the difference between profit and loss. A gravel quarry in Hartheim am Rhein, southwest Germany, is partially covered by artificial lakes. To determine the volumes of the above-water gravel dumping grounds an... (read more)

Effective Surveying Tool for Shallow-water Zones

A recent article provides an overview of satellite-derived bathymetry methods and how data can be integrated into survey campaigns, and showcases three use cases. Bathymetric data in shallow-water zones is of increasing importance to support various applications such as safe... (read more)

Inland Water Mapping

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)

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)

World Hydrography Day 2017 for HSB: Looking behind the Dikes

Hydrography is important to visualise the water floor. This can be done in various ways, from using a sounding stick to a remotely controlled singlebeam echosounder or a survey vessel manned 24/7. On Tuesday 20 June 2017, the worlds of dredging and hydrography were united at... (read more)

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)

Survey Data Management Critical to Port of Melbourne’s Operations

Survey data management is critical to the operation of the Port of Melbourne (PoM), primarily to support the safety of vessels operating through its channels. The PoM is one of Australia's busiest and largest container ports with 30 commercial berths, 21km of waterfront and... (read more)

Inland Water Mapping

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)

Hydrography for Continental Streamflow Modelling

Land surface hydrography now supports the modelling of continental-scale streamflow at high resolution and in near real time. The US National Hydrography Dataset contains about 2.7 million stream segments averaging 2km in length. This database establishes a national topologi... (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)

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)
