A number of software systems have been playing a key role in supporting the decision making activities in recent years but common problem in all that they cannot handle fuzzy data appropriately for "what-if" analysis. This paper proposes intelligent scenarios analysis system framework for marketing decision support which deals with crisp and fuzzy data like linguistic variable. Applying new approach "Hypothetical Database" for derived data that permits decision manager to manage views according to the need of organization and/or market environment. View in Hypothetical Database provides versatility in "What-If" analysis by using versions of "What-If" database and reduce data redundancy and data storage in updating. Using Fuzzy database will help to handle imprecise and uncertain information like "Linguistic variable" in a more human oriented process. Finally, the projected scenarios selected by decision manager will be aligned in a hierarchy according to the distance from "Ideal Vector" by using Fuzzy Multi-Criteria Decision Making method.

By using the prediction method of Karsten , the breaker wave height root mean square Hrms was computed as a function of water depth and the breaker wave energy was computed as a function of Hrms in Mean Higher High Water (MHHW) for 45 points at the Iraqi coastline in the north of the Arabian Gulf. The results showed that the gradient of Iraqi coast at the study area was flat and the predominant type of breaker waves was spilling.The highest value of the energy of these waves was 1214,258992 J/m 2 at point no. 45. The highest breaker wave height root mean square Hrms was 0.981 m at the same point.

Throughout Iraq, overall surface winds come from the northwest at 5-10 knots an average. Three stations A,B and C were selected situated along the southern entrance of Khor ABDULLAH which extended to the distance 20 km.Wave estimation depends on the method which is possible to be applied for computing the wind-sea significant wave height on a fully developed sea at storm area to the higher waves of greater importance in relation to their effect on ships or coastal structures, while beyond the storm area the swell significant wave height and swell period are computed by using Neumann and Pierson (1966) prediction method, the combined significant wave height is computed by using data of wind speed observed at 10 m over sea surface recorded at Abadan station in the north of Arabian gulf. The results shows that the higher wave height is around 1.7 m in summer season in the range of years 1990-2000,also the higher swell and combined waves are 1.3 m and 2.1 m in summer in the same range of years at the southern entrance of Khor ABDULLAH in accordance with the field data. The manner of increasing of the wind speed and wave height is parallel. The slope of coast at these stations is shallow and mild. The waves breakers occurs on coast are spilling and plunging breakers.
