CAE provides to public and private bodies evolved technologies to monitor the environmental risk due to natural events. Damaging Hydrogeological Events (DHEs) are defined as the occurrence of one or more simultaneous aforementioned phenomena. A method for the characterisation of DHEs based upon historic data is proposed. The method is aimed at assessing DHE-related hazard in terms of recurrence, severity, Abstract.

Dating brittle deformation events in faults from central Sweden: Preliminary results Furthermore, municipalities struggle not so much with the hydrogeological. Dear Colleagues, Damaging hydrogeological events (DHE) are periods of severe weather conditions affecting wide areas for several days, during which landslides, floods, storm surges, hail, wind, and lightning can cause huge damage and victims. The exponential growth of DHE that occurred worldwide in the last few decades may be related to the increasing frequency and magnitude of natural dangerous phenomena as a direct consequence of climate change, thus demanding a deep understanding of Hydrogeology (hydro-meaning water, and -geology meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust (commonly in aquifers). Background: Damaging Hydrogeological Events (DHEs) are severe weather periods during which floods, landslides, lightning, windstorms, hail or storm surges can harm people. Climate change is expected to increase the frequency/intensity of DHEs and, consequently, the potential harm to people. A damaging hydrogeological event (DHE) is characterized by two components: a rainfall event and a subsequent damage event, which is the result of floods and landslides triggered by rainfall. The characteristics of both events depend on climatic, geomorphological and anthropogenic factors.

Hydrogeological events

The triggering factors for each hydrogeological event were analysed into twofold approaches, with the final intent of ranking their magnitude in terms of consequent damages. Firstly, an analysis of precipitation was conducted using local rain-gauge data, comparing them against rainfall-threshold curves proposed by several authors.

Drinking water risk management: local government

As a whole, these periods of bad weather and triggered phenomena can be defined as damaging hydrogeological events (DHEs). We define a This study analyses monthly climatic data (rainfall, wet days, rainfall intensity, and temperature) and the annual maximum of short-duration rainfall (from 1 h to 5 days) to characterise climate variations, focusing on rainfall, and their effects on trends in damaging hydrogeological events (DHEs), defined as the occurrence of one or more simultaneous landslides and/or floods causing extensive damage. 2.1 Historical database of hydrogeological events 90 A group of past hydro geological events has been considered for the alpine area of Sondrio Province, northern Lombardy, Italy, Figure 1. This area was affected by excepti onal hydrogeological events in July 1987 causing extended damages and loss of lives (CNR, 2020) .
