Filter1D: Time Series Analysis Tool filter1d.m

• The Matlab utility provides users of the SMS, a one-stop package for preparing model input time series and allows users to interpolate, resample, filter, and transform any type of model forcing and supports SMS compatible file formats for ease of data transfer.
• The main feature of the software is the ability to apply high-pass, low-pass, band-pass, and band-stop filters to time series.
• There are many types of filters available, and each have their own advantages and disadvantages.
• Filter1D uses a windowed sinc filter which is a non-recursive finite impulse response filter.

TAP Interface

=== Tidal Analysis and Prediction software (TAP): TAP.rar

• • TAPtides is the ideal package to explore and develop preliminary or finalized tidal predictions from serial records spanning several weeks to several months.
  • Designed to be easy to use, its Graphical User Interface permits quick separation of a time series of water level measurements into its tidal and non-tidal components using a selective least squares harmonic reduction employing up to 35 tidal constituents.
  • After saving the tidal constants for the constituents selected during analysis, the user can generate predictions of the astronomical tide, the water level that varies at known tidal frequencies attributable to gravitational interactions between the earth, moon, and sun.

Matlab scripts

Read CMS-Flow solution files: readcmsh5.m

Description: Reads the CMS-Flow XMDF (*.h5) solution file in Matlab. Can read individual datasets are the whole solution.

Usage:

     filename = 'test_sol.h5';
     sol = readcmsh5(filename);
     wse = readcmsh5(filename,'Water_Elevation');
     [wse,uv] = readcmsh5(filename,'Water_Elevation','Current_Velocity');

Read SMS Time Series Data File (*.tsd): read_tsd.m:

Usage:

    [t,dat,name,units] = read_tsd(file);

Bin scatter data (x,y,z): xyzbin.m:

Example of xyzbin application to multibeam data with 5-m bins.

Description: Averages the x, y, and z values of points within the same bin. The grid used to define the bins may be user specified are calculated based on the extent of the scatter points.

Usage:

    [x,y,z] = xyzbin(...)
    [x,y,z] = xyzbin('infile',infile,'outfile',outfile,'dx',dx)
    [x,y,z] = xyzbin('x',xin,'y',yin,'z',zin,'dx',dx)
    [x,y,z] = xyzbin('x',xin,'y',yin,'z',zin,'dx',dx,'dy',dy)
    [x,y,z] = xyzbin('infile',infile,'dx',dx,'x0',x0,'y0',y0,'theta',theta)
