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)

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)

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)

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)

Inland Water Mapping

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)

Robust Data in Sensitive Environments

There are settings where an unmanned survey represents more than a safe, cost-effective alternative; it may be the only option. Capitol Lake in Olympia, WA, USA, is such a location. In this article, we report on a recent survey that highlights the advantages offered by an un... (read more)

When Bathymetry Determines Who Might Live and Who Might Die

The importance of bathymetry may be obvious to mariners, ocean modellers and marine geologists, but among the general public only the boating community seems to understand the importance of knowing water depths and the shape of the sea bottom. Most uses of bathymetry are not... (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)

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)

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)

Ice-jam Floods

The large, poleward flowing rivers of Siberia, such as the Ob River, experience persistent and severe floods when river ice breaks up in the spring. Ice-jams are common on the Tom River, a tributary of the Ob, resulting in a rapid rise in water levels upstream of the jam and... (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)

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)

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)
