Climate variability is an environmental phenomenon that has received considerable attention from all countries of the world, where it is certain that the heavy rain in unexpected places and irregular times and the accompanying floods and floods, the risks can reach the extent of disasters.
 This study was designed to identify and identify the risks and effects of increased rainfall on the mud-brick architecture of Omdurman. The researcher used the modern induction method. The study showed how to achieve this possibility through what can be found in elements Climate especially heat and rain and their impact on clay architecture in the region.
 • The study reached a number of results, including the development of a national and regional strategy for how to formulate scientific methods and mechanisms to address the problem and reduce its risks to the urban environment (clay architecture).• Invest in and request technical expertise and grants from major countries interested in environmental issues and changes in climate components (especially rain), sustainable development and water, through programs and projects in improving the resistance of clay architecture to the effects of climate change.
