Climate change is the most controversial issue at the international 
level to limit the continuing rise in temperatures in the world, and 
accordingly comes the leading role of the combination of the 
origins of interior architecture and other sciences in structuring a 
plastic and functional structure of interior architecture that is 
good at dealing with this thorny global controversy in dealing 
with the cosmic climate conflict and addressing it Therefore, 
hydrology found its role in paving the way for sustainable 
construction to improve the efficiency of the internal 
environment of the building and reflecting its capabilities and 
capabilities to enhance the principles of sustainability by taking 
advantage of the applied scientific study of the movement, 
distribution and management of water resources and enhancing 
the ability to adapt to all climatic conditions presented according 
to the integrated system of external environment standards and 
their reflection on interior space.
This research crystallizes the pivotal role of the impact of 
hydrology on the climatic conditioning of the interior 
architecture space, which is built on the principles of 
sustainability, which is reflected in the physical comfort and 
improvement of the productive capacity of the occupants of the 
interior architecture space. 
Which confirms the importance of the basis of hydrology, which 
is “water" and what it provides as a meaning of life and a 
formative and utilitarian ability through the tasks it performs: 
energy transfer tasks, biological and chemical tasks, recreational 
tasks, as well as its importance through the connection of various 
human activities with water, in addition to the link Human 
stability with the presence of water and the strengthening of its 
connection with nature through the manifestations of hydrology 
applications in the plastic and functional folds of sustainable 
internal architecture structures to adapt to the built environment 
in the future on scientific and technological foundations, to 
support the mutually beneficial relationship between nature and 
the built environment and humans in the discovery of the creative 
design energy of water in the development of space Interior 
architecture through the lens of resilience for sustainable climate 
to blur the line between function and aesthetics to create an 
innovative and integrated interior space.
