The monitoring and alert system ALMOND-F (Alarm and Monitoring System for Debris-Flow), which has been designed by SIAP+MICROS and CNR IRPI, is mainly devoted to:
•    ows,the issue of warnings for protection from debris and mud
•    ows for documentation and research purposes.the Multi-parametric integrated monitoring of debris
The ALMOND-F consists of an innovative detecting system that, thanks to the integrated use of 3 geophones and 1 level sensor, placed along a reach of the torrent to be monitored, allows to retrieve the following parameters for the characterization of the phenomena:
•    height of the main front and of possible further waves,
•    mean front speed,
•    peak discharge (a stable section must be present),
•    total volume of the debris flow (a stable section must be present),

The precision of any monitoring system depends on its calibration to better fit the features of the installation site. The ALMOND-F makes no exception and, in order to get a higher reliability of the retrieved information, we warmly SUGGEST a detailed evaluation about the choice of cation level,sensors, sampling and recording frequencies, signal ampli a careful choice of the method of installation of the geophones, a correct choice of the method for signal processing, a correct choice of the algorithm used for alarm issuing. The more these evaluation will be c installation site, the more the recorded datacustomized on the speci will be accurate and meaningful and the same for the issued warnings.
The main advantages given by the ALMOND-F when it's used as an alarm system compared to the traditional one using trip wires, pendulums or stage sensors are the following:
•    It uses passive type sensors (geophones) which don't need any power supply, and this allows its use in sites where there's no power supply and/or low insulation conditions,
•    It doesn't need any suspension structure, as required by other sensors, since the geophones can be installed directly in the terrain. This makes the installation easier and safer, because there's no risk of collapse for the retaining structures due to bank erosion,
•    It's not affected by torrent deviation generated by erosion and/or deposition, which instead could jeopardize the functionality of other types of monitoring systems. This appears particularly remarkable when ow monitoring is carried out for warning purpose,the debris-
•    It doesn't need to be installed in the close proximity of the torrent banks. This could be an essential advantage where the banks are extremely steep or subjected to landslide and collapse. The ALMOND-F cation of the geophonic signal,System permits to vary the ampli allowing the sensor installation even dozens of meters far from the torrent, granting great versatility to the system itself,
•    ow before the It detects the ground vibration generated by the debris  arrival of the debris flow frontat the cross section where the sensors are placed (often the sensors have to be installed very downsatream- for logistic needs). Thanks to its versatility, the ALMOND-F system can be placed very close to the triggering zone (usually in very inaccessible places) giving the warning alert many dozens of seconds earlier than other monitoring systems,
•    It allows to retrieve a larger quantity of monitoring data compared to other monitoring systems. It's possible to measure the intensity of soil vibration, its frequency and the shape of the debris-flow wave . The availability of a larger number of parameters permits the cation of more robust algorithms, able to reduce the number of identi false alarms.
The ALMOND-F is based on last version of SIAP+MICROS DA9000 data logger equipped with OS WIN CE embedded. The data logger is able to acquire and elaborate a very huge number of data, thus it's very adaptable to different purpose. The ALMOND-F with geophones can be customized according to different needs. The standard version of the ALMOND-F has got the following configuration:
    
Option:
The ALMOND-F is open and modular, such as to permit a variety of customization in order to make it interesting for different purpose. For example, the system could be integrated with the following hardware:
•    Rain gauge (for monitoring the activated precipitation),
•    Pulling sensors (for detecting the flow transit),
•    Pendulums (for detecting the flow transit),
•    Temperature and Humidity sensor,
•    Snow level sensor,
•    Anemometric sensor,
•    UHF, Satellite, Wi-Fi Communication system, …. Other.

Founded in 1992, Meteomodem is a French company specialized the field of the Upper-air observation, and more specifically in the domain of radiosounding. Today, it is one of the top leading radiosonde manufacturer and a major player in this specific business, Meteomodem customers include a large list of NMS’s (National Meteorological Services) worldwide including Meteo France among many others, but also international Research Institutes, Universities and Laboratories for Research or Air Traffic Management authorities (Like the ASECNA in Africa) or again Military and Army corps. Currently more than 120 Meteomodem systems (upper air stations) are operated in more than 60 countries throughout the world and are using Meteomodem radiosondes on a daily basis (Once or twice a day depending on their means). As a world reference in this niche market of radiosounding, Meteomodem never stop developing, diversifying its activities and skills to other of domains in meteorology and climatology. Modem cultivates its difference by its particular business model, promoting innovation and cooperation with our customers and partners, while ensuring flexibility and proximity from the technical, operational and commercial aspect. All of our products are “Made in France”. Meteomodem is an exporting company; indeed, a significant part of our turnover is made worldwide. Modem is an active protagonist of the French know-how exportation worldwide. Moreover, it is a dynamic member of Prometeo, a French association gathering the top leading French manufacturers and that aiming at promoting our vision of Meteorology. Meteomodem is deeply implicated in various radiosounding work groups, of course the WMO/CIMO Expert teams OPAG’s Upper at the WMO (World Meteorology Organization). It also participates of the European meteorology agency (EMS) or again the HMEI association, who regroups a large number of Meteorological Company around the world.

SIAP+MICROS S.r.l. was established in 2003 from the merge of SIAP Bologna (Bologna - Italy) and of MICROS, (San Fior – Italy), two leading Companies in the environmental monitoring system’s market. SIAP has been producing instruments for meteorology since 1925. In such a long time span, SIAP equipment have been installed almost worldwide, as result of well proven quality and realiability. MICROS has been active since 1976 in the designing and manufacturing of data acquisition and remote measurement and control for environmental and industrial applications. The advanced design and manufacturing flexibility made MICROS a safe referral in the measurement and data acquisition industry. SIAP+MICROS gathers together the technology and application know-how of both companies, and the broad variety of experiences and expertises makes the new Company worldwide unique, featuring one of the widest range of products and systems for the environmental and industrial monitoring industry backed by more than 85 years of application know-how. SIAP+MICROS is controlled by TEI Group. Originated by TEI S.p.A., a Company which has been working for more than 40 years in the environmental engineering, TEI Group provides SIAP+MICROS’ R&D with forefront directions towards emerging technologies.
