Summary, in English

Effectiveness of management would be seen when we have to ensure the accuracy of the output. This is possible if the model predictions are done based on the behavior of desired phenomena in the real world, using appropriate organizing data in a Geo-spatial Information System. Therefore all the aspects of a phenomenon must be considered. But most Geo-spatial Information Systems' databases use a version-based model structure for data storage that lacks the necessary capabilities in management of changeable information and consequently the historical connection between the old and new version of information cannot be recreated. In this study, in order to build dynamic raster data and create communication between the versions, the event-based data model structure has been used. The concept of version is examined, then a developed concept about evolutionary process of the version is presented and finally, the given model for effective changeability of the land cover on the run-off in SAMALGAN basin of KHORASAN SHOMALI, Iran, have been implemented in ARCGIS by using VBA programming language in ESRI ArcObjects, Model-builder and AGWA. The ability to maintain the structure of dynamic phenomena and reduce data storage volume is the most important capability in the designed database structure derived from this research
