Forecast and control systems for landslides: local sensor distributed networks integration, monitoring techniques and hydro-geological models.

Università degli Studi de L'Aquila
Abstract
The research project aims at combining complementary expertises from three Center of Excellence, namely CETEMPS, DEWS and TELEGEOMATICA, in order to solve problems of major social relevance, such as monitoring and control of unstable slopes. Our research proposal is innovative, as we intend to combine locally deployed sensors and remote sensing for acquisition of a multitude of physical parameters that are directly or indirectly related to those phenomena that may determine landslides events in unstable slopes. If compared to currently employed techniques, the method we intend to develop and test in our research is characterized by the use of advanced technologies such as remote sensing e dense wireless sensor networks: thus, a large set of measurements can be performed and collected, and then used to feed advanced models and algorithms, with the ultimate goal of performing more reliable and economic forecast tools.

The project consists of five Work Package (WP). WP0 is concerned with identification and classification of requirements of the whole monitoring system. WP1, WP2 and WP3 are concerned with specific activities developed and coordinated by DEWS, TELEGEOMATICA and CETEMPS, respectively. WP4 is entirely devoted to the integration of the various activities, and will foster closer cooperation among partners as long as the activities proceed. Integration will be finally focused on developing a test bed, that should demonstrate how to predict a landslide >>>

Research Objectives
Our project will pursue objectives in both methodological and applicative domains. In fact, we aim at developing methods for monitoring and control of unstable slopes, using measurement data collected by locally deployed wireless sensor network and remote sensing systems. The following main physical parameters will be taken into account for in situ measurements: temperature and humidity of the terrain at various levels, temperature and humidity of the lower atmosphere, acceleration. From the remote sensing side, we will be able to collect data on localization and intensity of rainfalls and snowfalls, which are intended as external solicitations to the dynamical model that describes a landslide.
From a detailed system model and a possibly rich sets of measurement reports, we try to estimate the risk of an incoming landslide on the monitored area. In this context, definition and validation of models that represent the status of a slope, their dependence on i) severe atmospheric events that may happen in that area, ii) humidity, temperature and other climate parameters, iii) humidity and temperature of the terrain), is a major efforts for performance and effectiveness of the entire system. Therefore, methodological tasks include (high level) mathematical models for landslide prediction, which combines the abovementioned set of measurements, as well as models for describing the behaviour of the energy critical wireless (sensor) networking context.

National and international background
The combination of geographic, geological and climatic factors makes Italy one of the European countries more prone to landslides. Italy shares with USA, India and Japan the record of the greatest economical loss due to landslides. The total amount of "landslide costs" (direct and indirect) for each of these countries ranges between 1 and 5 billions of dollars per year.
Heavy and/or persistent precipitations and sudden snow melt represent some relevant phenomena at the origin of landslides [37]. By experience, can be said that very often the typical condition that lead to the landslides are characterized by a period of persistent rain (15-20 days), within the seasonal averages, on which is superimposed an exceptional event of short duration (2, 3 days).

However, flow and outflow water modeling in areas with a complex orography represents an ambitious frontier for research activities in geophysics and in particular in hydrology. As opposed to the concentrated parameters hydrologic approach, based on simple space-independent models, scientific community is focused on the development of spatially semi-distributed models or fully distributed models. If on one hand this trend allowed a more realistic and geographically dependent soil state, on the other hand the high resolution characterization of geo-morphological and hydro-geological parameters represents a critical aspect from the soil parameter setting and in-situ measurements point of view.
