PRAMo - Probabilistic Flood Risk Analysis Model

Flood risk analysis usually addresses three question: (1) How do possible flood scenarios look like? (2) How likely is their occurrence? (3) What are the consequences? PRAMo is able to answer these questions and delivers information about the expected annual damage within a region. The model considers the spatially heterogeneous nature of flooding, direct damages of buildings and uses a multivariate algorithm for generation of synthetic events and thereby guarantees an estimation of damages.
Technology validated in relevant environment.
Fidelity of breadboard technology increases significantly. The basic technological components are integrated with reasonably realistic supporting elements so they can be tested in a simulated environment. Examples include “high-fidelity” laboratory integration of components.
PRAMo has been successfully tested and applied in the Austrian Federal Province of Vorarlberg and shows it capability to provide estimates of annual expected damages and damages associated with a recurrence interval of 100 and 200 years. This successful test in a relevant environment demonstrates that the model is ready for application elsewhere.

How does it work?

PRAMo is a software package that consists of three modules which interact fully automatically. The modules are: (1) a Hazard Module, (2) an Impact Module, and (3) a Risk Assessment Module. The above noted general questions about flood risk can be answered by means of these modules. PRAMo is a generic model which can be applied in any region, in which certain input data are available. These are: (i) terrain information, (ii) observed runoff time series, (iii) inundation maps, and (iv) building assets. The model reproduces a large data set of possible hazard scenarios, combines it with potential consequences and delivers information about the expected annual damages and damages associated a low probability of occurrence (e.g. 0.5% p.a.).
