the and you can see where you're coming to convene the session on natural about prediction and management and the prior presentation will be yeah yeah and then go chronological technique for avalanche not mapping with us by the market Charlie beings 18 minutes of the during the project of techniques for had the mapping graph the aims of this
work is to map of entries on the date of topographical image parameters in order to get the maps and to understand the average activity of the peculiar side what is true reconstructs specially counterpart path of emotion and to obtain data to test and verify the dimensional mathematical rather than these things are carried out by means of tools for that our gratitude and the knowledge of the that the area the 2 of strength in Norton will not work and 1 of large and the other is about the pain in the butt about by 2 main pair well this allergies also important because in the nineties you you challenge them interested in the all valid and after that there's a huge event that people have have forgotten that the there was the average phenomenon so they deal with homes and how this inside the check of the avalanche and so on something like that so that it happened in 1951 in in Switzerland may happen in the body a prosecutor is that then we have a special characters nations it we have to define the attentional potentially by means of a graph we have to that in mind expansion of potential risk and track and then to locate all that and potential that can detect why we have a camper conviction that meanwhile under general at the end of the the features and the use
needs also lend them education disturbance and these traits can be a reader can be reconstructed by individual scientists the shape and the tree and from the and even it is possible by means of the all of these techniques to reconstruct the frequency of the then the lake sort that out of the many many times to the effect of the braking energy the and public radio and this page of history that different the morphological and carried out with that achieved in the that are commonly used that dada like elevation contours in a map of the accrued event the other in the forest management plan and the aerial photographs in order to get a risk map is obtained with a standard technique that you're using their morphological criteria that out of the loop between and the the kind of values and a minimum starting and and let's be a little changes the other band more than 10 degrees the the that America to with the the mutation Madison that come from and of plan and the end of the day are already divided in categories and we have a lot of information about the in different types of education of we have a we divide them in different classes in order to have a different kind of protection from knowledge that is not the protection of the but think through all of the other actions in the vegetation but it protection from the in the formation of voluntary reduction from the starting point of our so
the determination of century getting ready for the made in this way we have morphological are actually can obtain with that of of features of ground and potentially dependent on digitization part that is called rich and then the trees director and go on a and information overload needed to obtain a risk map so we have a globally map
and 1 is divided in different classes then dendrochronological analogies and what is in the we have visible sign of avalanches that are left on the tree they have different kind of time the inclination of the trees broken down the plant shoot out about region with branches and shape that changes branch modification use them if you can have different kind of state the science and the time indicated by the red arrows and then we have changes in the growth of being there and because the change and kind of and changes remain in their growth rings of the plant so we have the in the damage tree when the 3
damaged by an avalanche we have a reduction of the grill while in another a man read by the presence of other plants that we have a region of the United the growth and on now that you know we have we can have some other countries like the formation of compression would in due to the in the when the plant the get out of the vertical there the formation of all this kind of
particularly with and then we have other kinds of indicators of guys in the military the ROC analysis can car and dramatic writing the they and also newsstands certainly is here that we have them what who work in the broken that where he attended college you find that that it that we the plant and then by the end of the year rings and examination of core and can cross section in we gotta have a field work workers so
we have to select the avalanche checks and is made mostly by the use of graphs and the selection of a most representative plants it with this kind of knowledge passage because the parents must be must be accorded inside the check outside in the understand the undisturbed forest to have it in a circle but it's something to compare to the
sampling that was carried out in in the 2 large vector in the October 1919 January 2000 and indeed of the opinion that we have a lot of something here between October and December 2001 a you see the representation of the area is that have been analyzed in laboratory in Switzerland a and that the technique is I don't been spinnaker particle of the here by the and we compared the average chronology of 1 of the forest and with the information of each the plant and then we have a across the patient and by the user of the intersection of various kinds of indicators then we will get we are to define appear in which should it has been all up and then immediately you here it is it into a larger we by combining the use of risk maps that we have obtained and and some different graph models some very simple like fool and that we have started from the starting and don't of the avalanche individuated by the the previous research carried out with we have individuated at some particularly in the it is so area that are possible published the operation was carried out using the 5 meters solution and by combining these with the
field at the beginning and that was carried out using the data from graphs and you got from the observation of the area under electric features school down the the area with the innovation and that also the geomorphological and observation of the area and it was
possible to delete the the having significant that the union and then the the what's called and buying the observations he do all that anomalous events that occured in 2001 that is the 1 that is in the default so being morphological modeling carried out with got to the end and the real behavior of the observed Alan shouldn't because what we have observed that the graphs we have also found that in reality we really want so we see what we did what is represented on the photo irrepresentable to endure total and there we be a graph with the to In the other example of the body you know and by the beginning and we were able to reconstruct the as part of a larger than it and so we were able to reconstruct the events in 1972 then in 1977 then in 1979 In a tricky he could have in 91 and to compare to the 2 of them and we have a some years but not for every year there in the data from the Allen and so we use these to compare it and it is what we adopted to yellow from 1991 that he did not uh absolutely matching so it's possible that global reconstruction of an event in in which JS morphologic analysis and dendrochronological around it is possible the global reconstruction of the starting and ending point also there will and and avalanche there being conclusion of the work . min a practical scientific at that so it is possible to reconstruct the frequency of knowledge that within the chronology and in it is possible to individuate old of large that that the with the recorded data and can be made with the chronology and that they it's possible to define yellowish share important on and by means of morphological interior and educational feature recognition and then and that you have proved to be effective to to produce 3 that and to locate neurologist area and there to represented in all also to represent the results all dendrochronological litigation the practical application may be useful information to test and calibrate dimensional model and the method that can pick out the lecture in the in already occurred in event that you could do that so it simply made by relatives who go out with the people that matter and then with a mandatory for the the acquired event so it may be that it not from the peak in the and it's possible to correctly and the future development are many of the in the long term reconstruction from 100 to 150 and tool to 150 years ago and it is particularly important in light that that he have shown to because we have to to understand if there is a requires the unity of the avalanche and it parents ampullaria maybe based in that thing that all and then have to refine DAS models provide a more accurate input data but now another viable like no conditions local local negation and some of the things that the investigation of possible connection between climate change anything justification of ownership phenomena but heart 2 things that we are trying to do now is that the cinematic reconstruction of analysis so being it the using of the all the valid because wouldn't acknowledge it is possible to understand that the you can use it the life of so we can try to connect the that of the full the and and now that it is needed to work on stock there's no on the dimension of the model and the the dimensional model and the last thing that we are doing is that we try to applied and knowledge use that to the brief flow phenomena have some information motions
it is hard to do how do you do practicality handling of the torque from knowledge indeed practically then develop they tend to have an apology carried out with the accord board there are some kind of
atoms in a uniform manner OK in which would give you would just take the course and then you have to according to to treat them as a tool and some work on on them to make them understandable by some instrumentation that is normally normally dendrochronological instrumentation for analogies inequality and the that each of or some of instrument and then maybe you can have an use other things like then and then commentary on all wood but is not always requested by the kind of how I I I I
I I I I I I I I I the only know so and because manual use dendrochronological techniques to understand and the nominal you try always different indicators just something 1 the and like that you don't take plant in which you have only part all you have only the the number of rows in the title the fact that they have many indicators and the menu different indicators uh and empirical not that will a much bigger and the that's all will phenomena a study along with adjustable eliminated that different than dendrochronological trends you and say 1 we had absolutely not in the in general when you have the analysis side and you have a lot 1 kind of problems so there's no way that generally a of the same kind in while you can have been different types different kinds of knowledge my name is bookmarklet and I just showed you a picture of the trees that and and here that that this is the time when the at a luncheon the part not non-monotonically because when you have this kind
of and confirmation of the of the data that is not
only avalanche but knowing the avalanche and you have Jew morphological properties the of the the fight but maybe also the prominence of the node at of so you have to to lot in it would be in the context is not possible to that it was an kind of on 1 particular indicators either OK for a situation you have to understand it anymore at all in the field of
