Conference Paper

In view of our geographical research expertise in the tropical mountains of Tigray (north Ethiopia) since 1994, our focus was deflected from geomorphology and environmental management to casualty recording and survival strategies, after the Tigray War started in November 2020. We created the "Atlas of the Humanitarian Situation", in which we chroni...

The digital age has brought about an explosion in the growth of data, of which data with a geographical component stands out. Proper use of geographical data comes with the need for correct coordinate reference systems (CRSs). They are considered the ultimate binder for interoperability between geospatial data actors and stakeholders. Moreover, CRS...

At the beginning of November 2020, an armed conflict emerged in Tigray, Ethiopia’s northernmost region. The objective of this ‘Atlas of the Humanitarian Situation’ is to document and map the situation in which approximately 6 million Tigrayans currently find themselves. For this, we contacted key informants in different districts of Tigray to colle...
Conference Paper
Full-text available
At the beginning of November 2020, after months of rising political tensions, an armed conflict emerged between the Government of Ethiopia and the - now ousted - Tigray Regional Government. As the conflict arose in the aftermath of a destructive locust plague and on top of the ongoing covid-19 pandemic, soon the realization came that the conflict w...

There are many sensors and measuring methods for detecting moving objects, each with its advantages and disadvantages. In active tracking methods (based on e.g. GNSS technology), the user is informed and actively participates, for instance by installing a smartphone app. These methods typically have the problem that only a limited part of the movin...

Beach Surface Moisture (BSM) is a key attribute in the coastal investigations of land-atmospheric water and energy fluxes, groundwater resource budgets and coastal beach/dune development. In this study, an attempt has been made for the first time to estimate BSM from terrestrial LiDAR intensity data based on the Support Vector Regression (SVR). A l...
Article
The measurement of surface moisture on beaches is vital for studying aeolian sand transport mechanisms, but existing techniques are not adequate for monitoring the surface moisture dynamics over a substantial beach section. In this study, we investigated the suitability of a new remote sensing method to monitor the spatiotemporal variation in surfa...
Article
Knowledge of aeolian sediment dynamics over an elevated berm with an upwind topographic obstacle is rather scarce and is of utmost importance for understanding aeolian transport from beach to dunes. This study reports on a field experiment designed to carry out simultaneous measurements of wind and aeolian sediment dynamics across a human-construct...
Article
Full-text available
Sustainable forest management heavily relies on the accurate estimation of tree parameters. Among others, the diameter at breast height (DBH) is important for extracting the volume and mass of an individual tree. For systematically estimating the volume of entire plots, airborne laser scanning (ALS) data are used. The estimation model is frequently...
Conference Paper

Two commonly used programming languages in geosciences are R and Python. Both languages come with inherent advantages and disadvantages. While Python is a general-purpose language with a readable syntax, R is built by statisticians and encompasses their specific language. In contrast with more nominative and static programming languages, like C++ o...
Article
Talus slopes are common places for debris storage in high‐mountain environments and form an important step in the alpine sediment cascade. To understand slope instabilities and sediment transfers, detailed investigations of talus slope geomorphology are needed. Therefore, this study presents a detailed analysis of a talus slope on Col du Sanetsch (...

In order to protect the Belgian coast, knowledge on natural sand dynamics is essential. Monitoring sand dynamics is commonly done through sediment budget analysis, which relies on determining the volumes of sediment added or removed from the coastal system. These volumetrics require precise and accurate 3D data of the terrain on different time stam...
Article
Early-stage aeolian protodunes, or ephemeral dunes, are ubiquitous features on the upper-beach, acting as requisite precursors to fully developed dunes. Their formation during high energy aeolian sand transport events plays an important role in the beach morphodynamics and sediment budget. However, little is documented about their life cycle from g...
Article
Full-text available
Surface moisture plays a key role in limiting the aeolian transport on sandy beaches. However, the existing measurement techniques cannot adequately characterize the spatial and temporal distribution of the beach surface moisture. In this study, a mobile terrestrial LiDAR (MTL) is demonstrated as a promising method to detect the beach surface moist...

Worldwide, flood events frequently have a dramatic impact on urban societies. Time is key during a flood event in order to evacuate vulnerable people at risk, minimize the socioeconomic , ecologic and cultural impact of the event and restore a society from this hazard as quickly as possible. Therefore, detecting a flood in near real-time and assess...
Article
Full-text available
Increasing urbanisation, changes in land use (e.g., more impervious area) and climate change have all led to an increasing frequency and severity of flood events and increased socio-economic impact. In order to deploy an urban flood disaster and risk management system, it is necessary to know what the consequences of a specific urban flood event ar...

Data and metadata products based on intensive terrestrial gravity measurements covering the Belgian territory have been established compliant to the new ISO19115‐1 profile for gravity‐related data. A short historical introduction on gravity measurements on the Belgian territory is presented, starting with the first gravity measurement in 1892. This...
Conference Paper
Digital elevation models play a crucial role in the analysis of complex spatial challenges. Given the international dimension of many environmental applications, elevation data have been integrated in the European INSPIRE directive (Annex II, Elevation theme). As a result, many types of data are offered in various formats by mapping agencies and go...

Sediment transport is a key element in intertidal beach morphodynamics, but measurements of sediment transport are often unreliable. The aim of this study is to quantify and investigate cross-shore sediment transport and the resulting topographic changes for a tide-dominated, sandy beach. Two fortnight-long field experiments were carried out during...

In high alpine environments, talus slopes are often inaccessible or unsafe due to their steep slopes (30 •-37 •), a high surface roughness, frequent rock falls or other hazardous geomorphic processes. Conventional approaches (Total Stations, Terrestrial Laser Scanners or differential Global Navigation Satellite Systems) to study its topography have...
