CHASM™ structure has been developed with a view to incorporating key hydrological processes in assessing the stability of a slope. In particular, the model has been developed with a focus on ease and simplicity of use, combined with a level of functionality that is considered appropriate to provide guidance on aspects of integrated hydrology slope stability applications. An important element of the development philosophy has been and continues to be , the publication of the CHASM™ methodology in the international scientific literature; an approach it is hoped delivers transparency to potential users.
