Predicting the occurrence of rainfall-induced landslides is a crucial task for civil protection purposes. Several landslide early warning systems are currently operating worldwide at different spatial scales. In Italy, landslide alerts are issued for territorial units named Alert Zones, covering a few thousand km². Usually, regional-scale warning models rely on rainfall thresholds, which require a few parameters and provide clear results in ...
Worldwide, landslides pose a serious threat to the population, causing fatalities, widespread damages, and significant economic losses. Different phenomena influence the stability of slopes and can cause landslides, among which the main factor is rainfall. Rainfall is strongly controlled and influenced by climate and its variations. Therefore, it is to be expected that climate changes influence slope stability at different temporal and ...
We developed GASAKe, Genetic Algorithm-based Self-Adaptive Kernel, a new model to predict the time of occurrence of rainfall induced landslides.
GASAKe predicts the time of occurrence of single landslides or groups of similar landslides, both shallow and deep-seated, using a threshold than when exceeded determines the initiation of the landslides. The triggering threshold is defined using historical information on rainfall and ...
Different approaches have been proposed to model landslide and erosion processes separately. Only a few attempts have been made to model landslide and erosion jointly. Some models consider the effects of landslides on sediment yield and transport. In other cases, landslides and erosion processes are components of a landscape evolution model. However, existing models do not describe jointly the triggering mechanisms of landslide and erosion ...
Using long-term rainfall records obtained by the rain gauge network of the former Italian Hydrographic Service, in cooperation with colleagues in other CNR Institutes (ISAC and ISAFOM), we have studied the changes in the rainfall regimes in Calabria, Southern Italy.
Applying appropriate statistical methods, we checked the completeness of the historical records, verifying consistency and missing values in the records. We used the obtained ...
The empirical rainfall thresholds while representing a useful approach used to forecast landslide occurrence in wide areas, are affected by several uncertainties related to the rainfall and the landslide information accuracy, the reconstruction of the rainfall events responsible for the failure, and the method to calculate the thresholds. Definition of the rainfall conditions responsible for landslides is a crucial issue and may contribute to ...
SM2RAIN is an innovative system for the estimation of the rainfall, based on measurements of the soil water content. SM2RAIN considers the soil as a natural rain gauge, and by measuring temporal variations of the soil water content, it estimates the rainfall falling on the soil, adopting a “bottom up” approach. Technically, SM2RAIN relies on the inversion of the soil water balance equation that computes the repartition of rainfall in ...
We have developed a new satellite rainfall product in near real-time. The product, called H64, is based on the integration of rainfall estimates obtained through two satellite sources. The developed algorithm combines estimates obtained by applying the SM2RAIN algorithm to satellite soil moisture data and those provided by a state-of-the-art product already operating on the full-disk area of the Meteosat satellites (60° West - 60° East, 60° ...
Water is at the centre of economic and social development; it is vital to maintain health, grow food, manage the environment, and create jobs. As well over half of the world’s potable water supply is extracted from rivers, either directly or from reservoirs, understanding the variability of the stored water on and below landmasses, i.e., total runoff, is of primary importance. In situ observations or land surface/hydrological models are ...
L'IRPI è da molti anni impegnato nel monitoraggio di variabili idrologiche (umidità del suolo, pioggia, portata e velocità dei corsi d'acqua) che è risultato fondamentale per la rappresentazione del processo di formazione del deflusso e quindi per lo studio delle piene e delle ...
SANF-RFI is a landslide early warning system along the RFI national railway Infrastructure.

In Italy, landslides are triggered by intense and/or prolonged rainfall. The spatial and temporal forecast of multiple landslides triggered by rainfall in wide areas relies primarily on empirical rainfall thresholds. It is widely believed that the thresholds are influenced by the local topographic (morphological), lithological, soil, and climatic settings. For this reason, it is necessary to define local rainfall thresholds. Reliable local ...

Monitoring the water cycle from satellite observations is one of the major goals of the EO community and closing the water budget has been a long-standing objective of international programs. After years of hard work, calibrating satellite data, improving inversion techniques, and facilitating the coherency of retrievals, it is admitted that the water cycle budget can now be ...
Quantitative information about precipitation is one vital input to meteorologists, hydrologic scientists, water resources managers, and environmental legislators. Yet, accurate measurement of precipitation over the relevant space and time scales remains a challenge. Soil moisture can be seen as the trace of the precipitation and, consequently, can be useful for providing a way to estimate rainfall accumulation or at least a new constrain to ...
State-of-the-art satellite rainfall products are often the only way for measuring rainfall in remote areas of the world. However, these products may fail in properly reproducing the amount of precipitation reaching the ground, which is needed for hydrological applications.
