Hello everyone!!
im just wondering, is it possible to find the hourly Tidal levels?
if we have understood the different factors contributing the Tidal levels, i guess it is possible to determine the Tidal wave levels.
i'm from the different background i don't know whether the techniques have developed for the estimation/deterimining the Tidal levels.
so please suggest if there is some method as such?
Hello,
There must be a theoretical calculation, but the easiest method is to look for "tide tables" for the location you are interested in. This will give you several free websites that will give predictions of high and low tide times, and tidal height over periods of several days from the present.
If you are after predictions for a year then nautical almanacs will give you that data.
To get the hourly heights, there is an interpolation method that can be used - which is often explained in the almanacs, but there are several explanations on the internet that may help - look for "tide height interpolation"
Probably depends on just where you are. In the US, NOAA publishes tidal graphs that give (essentially) a line of tidal height for any given time. This is, as mentioned above, based on a calculation appropriate for a single location. They will have tide locations scattered all over so it will be easy to get "close", but perhaps not exact. Also, the level of actual tidal height is affected by wind an barometric pressure. Onshore wind and low pressure could actually raise the level by a foot (30cm).
Many ports have tide tables published. A brief search found this for India. There did not seem to be links to data, so it may work for you, or added contacts with agency.

Hi Praveen,
For starters you may want to look at:

Hi Praveen,
There are two options:
1. generate tidal model by using global model of ocean tides. There are plenty models available freely, for example Tide Model Driver (TMD). You can run it in Fortran or Matlab. Here is the link http://volkov.oce.orst.edu/tides/global.html
2. instantly get observational dataset from University of Hawaii Sea Level Center (UHSLC). They provide hourly and daily sea level data globally. At least, there, you can find the nearest station to your area of interest. Here is the link https://uhslc.soest.hawaii.edu/data/?fd
Good luck
Jaya
