The global climate change imposes new strategies of prevention and protection against the effects of urban flooding. The main goal of this paper is the identification of areas exposed to flooding risk in the Craiova city, and the study was structured in two sections. In the first part we aimed to identify the changes of the hydrography in the Craiova city from the beginning of its urban expansion and the hydrotechnical works realized for flooding protection from the 19 th century until now. The reconstruction of the hydrography was based on the cartographic documents elaborated since the second half of the nineteenth century and on the previous research concerning the city's design, water supply and sewage system. In the second part we realized a Bluespots map comprised of the areas and the buildings possibly exposed to the risk of flooding during heavy rainfall periods. The Bluespots map was automatically obtained with the Cloudburst extension of ArcGIS, being based on DEM data and the cadastral map of the city, after a method firstly applied by the Danish government to assess flood risk areas due to Cloudburst phenomena in Copenhagen.
Current climate and practicing a modern and sustainable agriculture imply the need to rehabilitate the entire network of irrigation systems found in Băilești Plain. There are 9 irrigation systems with 1.015 km of canals, spread over an area of 194.648 ha. These large constructions, which cross the Danube meadow and terraces, induced morphological changes due to the canals built and the slopes resulted. By investigating the types of canals built and their morphometric values, we were able to estimate the quantity of relocated materials, 53.918.820 m3. Failure to fully utilize the irrigation systems, deforestation and defective use of agricultural land have led to their degradation and amplification of geomorphological processes, especially on sandy surfaces. A complete analysis of the irrigation systems regarding their functionality, the existence of the Organizations for Water Users and the stage of rehabilitation contracts was carried out. The National Plan for the Rehabilitation of the Main Irrigation Infrastructure in Romania, aims at restoring the initial parameters for the functioning of the stations and canals by 2020. The purpose is to increase the irrigated areas, which nowadays are kept at a low value (50.000 ha) which fluctuates year by year.
