Issues of terrestrial geodetic datum definition in VLBI data analysis

, 2023
The geodetic datum describes the absolute location, orientation and scale of the observed system with respect to a target frame. Since Very Long Baseline Interferometry (VLBI) observations only provide information on the relative relationships between ...

The Geocentric Orientation Vector for the Australian Geodetic Datum [PDF]

Geophysical Journal International, 1971
Summary The geocentric orientation vector is defined for the Australian Geodetic Datum on the assumption that the geoid has the same potential as the value on Reference Ellipsoid 1967 on adopting Reference System 1967. It is shown that only the free air geoid need be considered to provide the required definition in the Australian region with a ...

Strategic Assessment of Treated Wastewater Reuse Potential in Brazilian Watersheds Using Analytic Hierarchy Process

Engineering Reports, Volume 8, Issue 5, May 2026.
Assessment of treated wastewater reuse potential in two Brazilian river basins using the Analytic Hierarchy Process (AHP). The map illustrates the Rio dos Sinos Watershed, where industrial reuse predominates (46%), while in the Rio Sapucaí Watershed reuse for irrigation is dominant (68%).

Geomorphic Effectiveness of an Extreme Flood in a Mountain River: Evidence From Pre‐ and Post‐Event Surveys in a Subtropical Region of Southern Brazil

Hydrological Processes, Volume 40, Issue 5, May 2026.
The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.

Improving the Accuracy of Polar Motion Prediction by Combining Least Squares and the iTransformer Model

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Polar motion prediction is an important means to study the dynamics of Earth's rotation and detect the internal structure of the Earth. This paper proposes an LS + iTransformer method that combines the least squares (LS) method with the iTransformer deep learning model. Using IERS EOP 20 C04 data from 2000 to 2022, Fast Fourier Transform (FFT)

Quantifying the Sea Level and Estuary Contributions to Changing High Water Levels in Four Major Australian Estuaries

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Coastal inundation occurs when the total height of mean sea level (MSL), tide, and surge, including subsequent propagation into estuaries, exceeds a given threshold. We developed a nonparametric Joint Probability of Maxima Method and applied to four major Australian estuaries, deriving frequency‐based exceedance thresholds and quantifying the ...
