Changes in precipitation patterns affect the amounts and types of precipitation over various time periods. These changes primarily have an impact on water management, ecosystems, agriculture, and forestry. Other water-related activities such as tourism and inland shipping are also affected. Moderate changes in precipitation have little minor impact on buildings but can affect the indoor climate due to persistent moisture and promote mold growth. Prolonged drought can lead to a decline in groundwater levels, which in extreme cases can cause land subsidence and, in some cases, negatively impact building structures.
Our risk assessment is based on the average annual precipitation and its future changes, without distinguishing between types of precipitation. A vulnerability and risk value are assigned to the average annual precipitation depending on the object under investigation.
