Q8Cis Apps is an Engineering applications for : - 1D Hydrodynamic's Prediction for Arabian Gulf waters [based on KGulf model {Al-Salem 2009}] Tidal range and the speed of the current can affect Shipping - entering/leaving harbours, coastal areas Information for study effect of sediment/pollutant transport. Coastal fishing This Apps allows user to setup a station in Arabian Gulf waters for Hydrodynamic's Prediction at selected [Longitude/Latitude]. Based on the amplitude and phase a harmonic constituents (22 constituents) will be predicted and used. Also it can be recall at any time from stored file in Directory for more prediction. Time limit for water hydrodynamic prediction can be from 1979 to 2035. Hourly Display. - Global Water Level Prediction [based on KTide model {Al-Salem 2004} ] Prediction of tidal variations is of importance in a wide range of practical applications such as: Navigation through inter-coastal waterways, and within estuaries, bays, harbors and fishing. The information provided by this apps can be further used as input for tidal circulation models. Q8Cis apps is capable to predict water level variation due to tides at a number of stations [1325 stations] in the Global waters. The apps will display for user a number of Continents Icon to select a station as follow: Asia Region Africa Region Europe Region North America Region South America Region 
 Time limit can be select from 1979 to 2035. Hourly Display. Q8Cis apps provide data Analysis for Data Table output Predicted tidal harmonic constituents for the selected location Tidal current Statistic of Frequency table [For 1D Hydrodynamic's tidal current Prediction] Tidal current Rose Plot [For 1D Hydrodynamic's tidal current Prediction] Q8CIS app results was validated with other model for tidal current and water levels prediction it was found to provide good results.
