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:

Inland Water Mapping

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.

Mapping a Hyper-acid Crater Lake with a USV

The 2,708m-high Poás Volcano is one of the most active volcanoes in Costa Rica, located 35km northwest of the capital San José. This stratovolcano contains a 300m-wide crater lake called the Laguna Caliente (‘hot lagoon’) filled with naturally hot,... (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)

Technology in Focus: Acoustic Doppler Current Profilers (ADCP)

Rather than a spinning propeller, the Acoustic Doppler Current Profiler (ADCP) - 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 article explains the... (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)

Inland Water Mapping

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)

58 Years of Paraguay River Mapping

A major part of Paraguay River’s sounding and signalling is maintained by the Brazilian Navy. Trying to stay abreast of the state of the art on inland hydrography and cartography, the Western Nautical Signalling Service briefly presents its past, current status, innova... (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)

Environmental Data ­Sharing and Publishing

The Port of London Authority (PLA) has had an extensive tide gauge network for many years. However, the existing system, installed in the 1990s was becoming increasingly unreliable providing inconsistent information due to a number of factors. There was a pressing need to de... (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)

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)

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)

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)

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)
