Nursery pot size, not planting density, affects vegetation performance in a restored semi‐arid wetland

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Coastal wetland restoration often involves planting nursery‐grown potted plants to accelerate vegetation development, particularly when stressful conditions or insufficient source material inhibit natural recruitment. Under these conditions, planting more densely or larger, more developed plants may increase vegetation survival ...

High and dry: the persistence of diverse coastal marsh communities depends on available upland area and connection to surrounding waters

open access: yesRestoration Ecology, EarlyView.
Sea‐level‐rise and alterations to natural hydrology have contributed to coastal land loss. To combat coastal land loss and maintain the ecosystem services provided by marshes, marsh creation has been broadly implemented. Marsh creation projects can be performed in conjunction with the construction of elevated terrestrial ridges that seek to mimic ...

Testing of the point accuracy of measurements by the RTK method at different distances of the reference station for monitoring of the dynamic effect in a subsidence basin [PDF]

open access: yesActa Montanistica Slovaca, 2007
In the area of Technical University in Ostrava were stabilized 35 points for testing of the accuracy of RTK measurement. All points of the testing base line were located by a new digital leveling instrument Leica DNA 03 with a precise leveling line.

Asynchronous RTK Method for Detecting the Stability of the Reference Station in GNSS Deformation Monitoring

open access: yesSensors, 2020
The real-time kinematic (RTK) positioning technique of global navigation satellite systems (GNSS) has been widely used for deformation monitoring in the past several decades. The RTK technique can provide relative displacements in a local reference frame

3D effects of seawater on electrical resistivity tomography near shorelines—Challenges and possible solutions inferred from synthetic and field data

open access: yesNear Surface Geophysics, Volume 24, Issue 4, Page 364-391, August 2026.
Abstract Electrical resistivity tomography (ERT) is one of the most widely used geophysical techniques for hydrogeological questions, such as investigating the groundwater transition zone between land and sea. The interpretation of 2D coast‐parallel ERT profiles is challenging because most of the electrical current flows through the highly conductive ...

Application of the Real-Time Kinematic Global Positioning System in Bridge Safety Monitoring [PDF]

open access: yes, 2005
A real-time kinematic (RTK) global positioning system (GPS) has been developed and installed on the Human Bridge (China) for on-line monitoring of bridge deck movement, which may occur as a result of seismic activity, traffic load, and such environmental
