“…Such dust storms also reduce visibility along roads and may cause traffic accidents. The geological hazards need certain geological conditions to be developed at certain areas [16]. Therefore, each type of the four main geological hazards, which are acting at different parts of Al-Anbar Governorate is developed at certain areas.…”

Al-Anbar Governorate has the largest coverage area among the 18 Iraqi gover-norates. The coverage area is about 138 579 km2 forming about 32% of the whole coverage area of the Iraqi territory. The governorate forms the western part of Iraq representing the Iraqi Western Desert and a small part north of the Eu-phrates River within the Jazira Plain. This large coverage area with diversity of rock types with large time span (Permi-an – Pleistocene) and different topographic forms have contributed to develop-ment of different types of geological hazards, which act at different parts of the governorate with different intensities and different damages caused to the infra-structure and community, even life losses. Three main types of geological hazards are active in the governorate; these are: 1) Floods, 2) Karstification, and 3) Swell-ing (Expensive) clays; however, other types like mass movements, depressions, active tectonic areas are also present but with less significance as their risks and caused damages to the community and infrastructure is concerned.

“…Despite being deemed a low-risk country in terms of geological hazards compared to some of its European neighbours (Giles, 2020), geohazards in Great Britain (GB) still cause costly delays and disruption to the transport network. For instance, shrink-swell issues alone are estimated to have cost the economy £3 billion over the last decades (GeoClimate UKCP09 and UKCP18, https://www.bgs.ac.uk/datasets/geoclimate-ukcp09-and-ukcp18/).…”

At the time of its development, GeoSure was created using expert knowledge based on a thorough understanding of the engineering geology of the rocks and soils of Great Britian. The ability to use a data-driven methodology to develop a national scale landslide susceptibility was not possible due to the relatively small size of the landslide inventory at the time. In the intervening 20 years the National Landslide Database has grown from around 6000 points to over 18,000 records today and continues to be added to. With the availability of this additional inventory, new data-driven solutions could be utilised. Here, we tested a Bernoulli likelihood model to estimate the probability of debris flow occurrence and a log-Gaussian Cox process model to estimate the rate of debris flow occurrence per slope unit. Scotland was selected as the test site for a preliminary experiment, which could potentially be extended to the whole British landscape in the future. Inference techniques for both of these models are applied within a Bayesian framework. The Bayesian framework can work with the two models as additive structures, which allows for the incorporation of the spatial and covariate information in a flexible way. The framework also provides uncertainty estimates with model outcomes. We also explored consideration on how to communicate uncertainty estimates together with model predictions in a way that would ensure an integrated framework for master planners to use with ease, even if administrators do not have a specific statistical background. Interestingly, the spatial predictive patterns obtained do not stray away from those of the previous GeoSure methodology, but rigorous numerical modelling now offers objectivity and a much richer predictive description.
