Coastal Information System (C.I.S.)

The Coastal Information System CIS is a hydrodynamic atlas for the Arabian
Gulf. It contains of wave data, tidal data and Wind data.

Wave Data
The wave data was hindcasted using wind data obtained from the European Center for Medium Range Weather ECMWF.
The KISR WAM model was used for that purpose. The data covers the years 1993 till 2009 and is available
on a 0.1 degree grid for the Arabian Gulf as shown in Fig. 1. The data includes the significant wave height,
the mean wave period for the wave spectra and the mean wave direction.

The data covers:
 Area limits are
Longitude 47 deg 24 min to longitude of 56 deg 48 min
Latitude 23 deg 48 min to Latitude of 30 deg 30 min
 The available grid system (dx / dy) is 0.1 degree. Or (6 min)
 Time limits are
Years Jan. 1993 Till Dec. 2009 Data Store in hourly system
The data includes the significant wave height, the mean wave period for the
wave spectra and the mean wave direction.
For wave data the following can be provided:
 Time series of wave height, period, and direction at any location.
 Wave rose as a plot and table at any location (monthly or yearly).
 Two dimensional wave data at a certain instant.
 Long term analysis of the wave data (100 year wave).

Grid used for the Arabian Gulf WAM model.


Hydrodynamic data
The tidal hydrodynamic data was generated using a tidal finite element hydrodynamic model for
the Arabian Gulf. The model boundary was applied at the Striate of Hormoz. The data
includes the tidal current and the water level over a nonuniform grid for the Arabian Gulf and the
Kuwaiti territorial waters.

The hydrodynamic data can be provided for:
 Time series of tidal water levels or currents at any location.
 Two dimensional hydrodynamic data at a certain instant.
 Tidal constituents at any location.

RMA Grid Covering the Arabian Gulf.
RMA Grid for the Northern Part of the Arabian Gulf


Four other grids were setup for the Kuwaiti territorial waters that can be used to provide more detailed data
at different locations in Kuwait.
