These data are from tidal resource characterization measurements collected between April and July 2017 in Western Passage near Eastport, Maine, USA. The dataset contains the following four sub-datasets, each of which is described in more detail in the README.pdf. 1. A bottom-mounted Teledyne RDI Workhorse 600 kHz acoustic Doppler current profiler (ADCP) was deployed at 44.92015 N, 66.98915 W in ~50 m of water from 3 April to 18 July (106 days). Data were recorded in 6-minute increments in the ENU (East, magnetic North, Up) coordinate system with bin-mapping enabled. 2. A bottom-mounted Nortek Signature 500 kHz ADCP was deployed at 44.92192 N, 66.98913 W in ~50 m of water from 4 April to 18 July (105 days). Data were sampled and recorded at 2 Hz and recorded in the ENU (East, magnetic North, Up) coordinate system. 3. Between those stations along a cross-channel transect, a Stable Tidal Turbulence Mooring (STTM) positioned ~10 m above the seabed was deployed for one week during a spring tide. The STTM was outfitted with two Nortek Vector acoustic Doppler velocimeters equipped with inertial motion units (ADVs), a bottom-tracking downward-looking Teledyne RDI Workhorse 600 kHz ADCP to provide motion-corrected flow and turbulence characteristics at high temporal resolution, and an upward-looking Teledyne RDI Sentinel V20 ADCP. The STTM was deployed at 44.92098 N, 66.98922 W from 24-31 May. 4. A vessel-mounted Teledyne RDI Workhorse 300 kHz ADCP collected current data along three transects over two days, 4-5 April. The data processing used DOLfYN version 0.11.2. All hdf5 files (i.e., files ending in `.h5`) contained here can be opened using that version of DOLfYN (e.g., `dat = dolfyn.load('')`). All distances are in meters (e.g., depth, range, MLLW, hab, eta, z_), and all velocities in m/s. See the DOLfYN documentation https://lkilcher.github.io/dolfyn/), and/or the Nortek and Teledyne RDI documentation for additional details. Additional details on the dataset can be found in the README.pdf, including: - Format details of each data file. - How to regenerate the data-processing (using the files in the `wp2017_processing.zip` archive).

Wave tank tests at Stevens Institute of Technology quantified the ability of near-surface platforms to concentrate wave energy over the platform. Due to the instantaneous change in water depth, mass, energy, and power are conserved in this process. The energy and power concentration factors ranged from 1 to 4 times the incident wave power as a function of incident wave period, wave height, and platform depth. Platform slope was set to zero for all 300 plus wave runs at platform top surface depths varying from 0.15 m to 1.10 m. This data set is extremely valuable to the MHK industry as water particle velocities over the platform were recorded at velocities on the order of 4x incident maximum orbital velocities based on Airy/Navier-Stokes theory. This term has been used "A change in effective water depth over which waves propagate". The only way I have been able to get the data to align with Airy wave theory is to use the top of tension leg platform (TLP) depth and a wave height corresponding to the change in the free surface elevation over the platform. The discrete change in effective water depth over which waves propagate is a topic of interest for fundamental hydrodynamic research as this implies there is an instantaneous convergence of group and phase velocities of waves at the TLP edge which shears the incident waves. This high shear rate makes the inviscid and irrotational assumptions and potential flow analysis invalid. This data set can be used as part of benchmarking any CFD which may be used to analyze this flow field. Using the top of the TLP as the "h" and full free-surface elevation change over the platform for "H", the maximum orbital velocities measured align with Airy/Navier-Stokes equations. If the tank depth is used for "h", or incident wave height is used for "H", the equations do not align with the data. Note that the SurfWEC system involves a non-inertial reference frame as the fully-submerged TLP is continuously experiencing positive and negative accelerations in most wave conditions; therefore, when a spring-mass (regenerative AHC winch - float) system is used for PTO, the "pseudo" centrifugal force must be accounted for in the loading to the system.

This dataset shows the minimum vertical clearance (in metres) of bridges over State Roads in NSW. This information is primarily for bridges on or over State Roads managed by Transport for NSW. With some exceptions, there is no information on structures on Regional or Local roads. Except for gazetted 4.6m clearance routes, a permit from Transport for NSW is required for any vehicle higher than 4.3m in height, to drive on State Roads. **Disclaimer** *The NSW State Roads Vertical Clearances dataset available on or from this website is intended as a general reference source and provided for information purposes only.

Contains the height clearance of overhead structures on arterial roads (freeways, highways, and main roads) as published on the Vicroads website. This dataset indicates the clearance between the road surface and overhead structures and is intended to assist heavy vehicle operators and drivers to plan their routes.About This Dataset
