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.

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)

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)

Surveying Japanese Inland and Coastal Waters

In March 2015, Leica Geosystems conducted a series of demonstration surveys in Japan with the HawkEye III Airborne Topographic Bathymetric Lidar system. This demonstration was designed to prove the depth performance and general capabilities of the HawkEye III system in... (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)

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)

Lidar Bathymetry on the Alaskan North Slope

In June 2014, the Bureau of Economic Geology, a research unit at the University of Texas at Austin, was contracted to conduct an airborne bathymetric Lidar survey on the Alaskan North Slope. The purpose of the project was to further determine, understand, and map the local l... (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)

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)

Introducing GIS to Support Maritime Accessibility

With over 500 line connections to and from more than 1,000 ports around the globe, the Port of Rotterdam in The Netherlands is the cornerstone of international freight transport. It is the perfect base for import and export and a gateway to the European market and... (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)

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)

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)

Centralised Data for Hamburg Port Authority

The Port of Hamburg is the third-largest container port in Europe and among the biggest in the world. There are almost 300 berths with a total of 43 kilometres of quay servicing around 9,000 ships per year. The Hamburg Port Authority (HPA) is responsible for the ma... (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)
