This research presents methods of creating digital maps for floodplain delineation and flood probability studies and storing them in a geodatabase. Methods for creating a geodatabase for water resources outside of a GIS are presented. The geodatabase follows the ArcHydro data model. Methods are also shown for creating digital flood maps and storing them in the geodatabase. These flood maps, defining the floodplain boundary and flood probability, are stored in a digital format ready for use in a FEMA flood hazard project, allowing for better archival methods and reproducibility.

This dissertation thesis deals with new progressive channel coding methods for data transmission using satellite transponder. The design of the system for SMS transmission, in which novel turbo coding methods are applied, is discussed too. An achievement of the lowest output power and the smallest user aperture is the principal aim of the new method applications. Design of system that would be able to the error free SMS transmission by very low signal to noise ratio is analyzed in this dissertation thesis. The work is focused on energy budget, modification and implementation of new turbo code types and using unique properties, development of new bit error rate estimation methods and methods for determination of final SMS form. The main contribution is the new type of turbo code development that have optimal properties for this usage, development of new bit error rate estimation method and development of method that is able to determine final form of SMS on the basis SMS frame structure and turbo decoding theory when the bit error rate is not zero.
