Web Processing Services for Shallow Landslide

Abstract: This work evaluates the capability of Web Processing Service (WPS) to foster the shallow landslides hazard awareness. In particular this study demonstrates how the WPS can provide an ideal environment for the development of real-time applications by creating a process chain able to couple two widely used models, TRIGRS and DFWALK, respectively applied for (i) the localization and characterization of areas susceptible to shallow landslides and (ii) the assessment of these landslides run-out in case of collapse. The service has been built with the PyWPS software by integrating the models through the GIS GRASS. The application, tested for the case study of Ha Giang (Vietnam), can be generally deployed and used both as service for shallow landslide hazard forecast and as a tool for the identification of vulnerable areas for emergency planning design.

Uses of online geoprocessing technology in analyses and case studies: a systematic analysis of literature
TL;DR: The required adaptation of technology for user tasks is identified as major barrier for the wide use of online geoprocessing and further research needs to assess user tasks and how online geop rocessing can provide the required functions in a user-oriented manner.

TL;DR: A load testing of the HELIDEM geo-portal, which is an example of interoperability between a number of standard geospatial services as defined by the Open Geospatial Consortium, confirms that the implemented solution is robust, in fact no system failure was recorded during the analysis.

Landslide triggering by rain infiltration
TL;DR: In this article, a mathematical model that uses reduced forms of the Richards equation to evaluate the effects of rainfall infiltration on landslide occurrence, timing, depth, and acceleration in diverse situations is presented.
