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)

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)

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

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)

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)

Fluvial Hydrography Workshop in Peru

The 2nd Fluvial Hydrography Workshop, organised and hosted by the Peru Hydrographic Service for Navigation of the Amazon (SHNA), was held in Iquitos, Peru, from 12 to 13 November 2012. Moderated by CDR Hugo Montoro (Commander, SHNA), this was a follow-on to the 1st Workshop... (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)

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)

Multi-purpose ENCs for Ports

Ports require access to a wide range of data and information to function safely and efficiently. Some of that data is acquired from external stakeholders but most is generated internally within the port. It is very often managed and held within a single software application,... (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)

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)

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)

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)
