As the results of those impacts, we are facing with shifting the weather patterns, which cause extreme flood and drought conditions, and the communities will be ultimately influenced by those extreme conditions on an unprecedented scale. In addition to shifting weather patterns, climate change and climate variability could make the water resources and the water infrastructures vulnerable.

To exemplify, we encounter rising temperature accompany with decrease of rainfall and fewer runoffs into the streams and surface storages. Hence, the surface water storages (reservoirs) are affected by the long-term droughts as evaporation leads to losing a significant amount of water from the surface storages. It is plausible to face profound changes in the water cycle as a result of climate change. Hence, we will plausibly have less available water supplies which are the considerable concern for the urban water sector, agricultural irrigation and ecosystems.

To overcome the climate change challenges and sustaining water supplies, making our water supplies and water infrastructures climate-resilience is a necessity. A climate-resilience infrastructure defines as an infrastructure which plans, designs, and constructs so that it withstands, operates and adapts with the climate variation all over its life. By ensuring that our water supplies and our water infrastructures are climate-resilience, we could decline direct damages of climate change and also, decline the possible costs of disruption which indirectly affect the infrastructures.
