Interpreting C-band InSAR ground deformation data for large-scale groundwater management in Australia

Pascal Castellazzi; Wolfgang Schmid

Journal of Hydrology: Regional Studies, Vol. 34 · 2021 · Inggris · DOAJ Scopus

Study region: Three regions across Australia, covering a total of ∼350,000 km2: the Perth basin in Western Australia, Northern New South Wales (Border Rivers, Gwydir, Lower Namoi and Condamine catchments), and Southern New South Wales (Murrumbidgee, Lachlan, Murray and Billabong-Yanco catchments)…

Understanding the Spatial Variability of the Relationship between InSAR-Derived Deformation and Groundwater Level Using Machine Learning

Guobin Fu; Wolfgang Schmid; Pascal Castellazzi

Geosciences, Vol. 13 No. 5 · 2023 · Inggris · DOAJ Scopus

The interferometric synthetic aperture radar (InSAR) technique was used in this study to derive the temporal and spatial information of ground deformation and explore its temporal correlation with groundwater dynamics. The random forest (RF) machine learning method was used to model the spatial…

Assessing the efficiency of mitigation measures to reduce groundwater depletion and related land subsidence in Querétaro (Central Mexico) from decadal InSAR observations

Pascal Castellazzi; Jaime Garfias; Richard Martel

International Journal of Applied Earth Observations and Geoinformation, Vol. 105 · 2021 · Inggris · DOAJ Scopus

Groundwater overexploitation occurs throughout Central Mexico and is a major threat to the sustainable development of the region. The two most direct impacts are on groundwater/surface water interactions and uneven land subsidence causing ground fracturing. The latter implies frequent and costly…

Nationwide Subsidence in Bahrain Island: Drivers and Implications for Relative Sea-Level Rise

Jonathan C. L. Normand; Essam Heggy; Pascal Castellazzi

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Vol. 16 · 2023 · Inggris · DOAJ Scopus

The IPCC-AR6 report suggests that the sea-level in the Persian Gulf is expected to rise by 2.1–4.9 mm/year by 2100, which is lower than the global projections of 4–14 mm/year. However, a central nationwide ground subsidence in Bahrain's low-lying island can aggravate these figures. The island is…

High Resolution Mapping of Ice Mass Loss in the Gulf of Alaska From Constrained Forward Modeling of GRACE Data

Cheick Doumbia; Pascal Castellazzi; Alain N. Rousseau dkk.

Frontiers in Earth Science, Vol. 7 · 2020 · Inggris · DOAJ Scopus

The resolution of Gravity Recovery And Climate Experiment (GRACE) Terrestrial Water Storage (TWS) change data is too low to discriminate mass variations at the scale of glaciers, small ensemble of glaciers, or icefields. In this paper, we apply an iterative constraint modeling strategy over the…

Corrigendum: High Resolution Mapping of Ice Mass Loss in the Gulf of Alaska From Constrained Forward Modeling of GRACE Data

Cheick Doumbia; Pascal Castellazzi; Alain N. Rousseau dkk.

Frontiers in Earth Science, Vol. 8 · 2020 · Inggris · DOAJ Scopus

Accuracy of Lysimeters for Dissolved Copper, Antimony, Lead, and Zinc Sampling under Small Arms Backstop

Richard Martel; Pascal Castellazzi; Luc Trépanier dkk.

Vadose Zone Journal, Vol. 13 No. 8 · 2014 · Inggris · DOAJ Scopus

Three assays were conducted to evaluate the reliability of lysimeters in detecting concentrations of Cu, Pb, Sb, and Zn in interstitial water of the vadose zone. Two box lysimeters (BLs) made from polyvinyl chloride (PVC) and polyvinylidene fluoride (PVDF) and three tension lysimeters (TLs) of…

Applications of Satellite Radar Imagery for Hazard Monitoring: Insights from Australia

Amy L. Parker; Pascal Castellazzi; Thomas Fuhrmann dkk.

Remote Sensing, Vol. 13 No. 8 · 2021 · Inggris · DOAJ Scopus

Earth observation (EO) satellites facilitate hazard monitoring and mapping over large-scale and remote areas. Despite Synthetic Aperture Radar (SAR) satellites being well-documented as a hazard monitoring tool, the uptake of these data is geographically variable, with the Australian continent being…

Integrating GRACE and InSAR Data to Assess Land Surface Displacement From Managed Aquifer Recharge

Ikechukwu Kalu; Pascal Castellazzi; Christopher E. Ndehedehe dkk.

Water Resources Research, Vol. 62 No. 5 · 2026 · Inggris · DOAJ Scopus

Abstract Satellite‐based monitoring of groundwater changes and their surface effects is crucial for understanding hydrological processes and managing water resources in an era of increasing water scarcity. The Gravity Recovery and Climate Experiment follow‐on (GRACE‐FO) mission provides global…

Assessment of hydrologic connectivity in an ungauged wetland with InSAR observations

Fernando Jaramillo; Ian Brown; Pascal Castellazzi dkk.

Environmental Research Letters, Vol. 13 No. 2 · 2018 · Inggris · DOAJ Scopus

The Ciénaga Grande de Santa Marta (CGSM) is one of the world’s most productive tropical wetlands and one that has witnessed some of the greatest recorded dieback of mangroves. Human-driven loss of hydrologic connectivity by roads, artificial channels and water flow regulation appears to be the…

The Potential of Hydrogeodesy to Address Water‐Related and Sustainability Challenges

Fernando Jaramillo; Saeid Aminjafari; Pascal Castellazzi dkk.

Water Resources Research, Vol. 60 No. 11 · 2024 · Inggris · DOAJ Scopus

Abstract Increasing climatic and human pressures are changing the world's water resources and hydrological processes at unprecedented rates. Understanding these changes requires comprehensive monitoring of water resources. Hydrogeodesy, the science that measures the Earth's solid and aquatic…
