These processes are due mainly to the total solar irradiance variations, followed by weather and climate changes. The interconnection between the solar cycles and decadal changes of rainfalls over Bulgaria is investigated by means of reconstructed Total Solar Irradiance TSI, precipitation from meteorological stations Sofia, Varna, and Palmer Drought Severity Index (PDSI) for the period 1899–2015. The decadal oscillations of precipitation and TSI with periods corresponding to the sunspots (11 years), solar magnetic cycle (22 years), equatorial solar asymmetry (45 years), Gleissberg cycle (70–100 years) and their harmonics are compared and analyzed. Models of decadal variations of PDSI and precipitation, based on solar cycles and harmonics, are created. The periods with rainfall and PDSI maxima are calculated on a century time span and a forecast of landslides is determined.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133738304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One part of landslides in Northeast Bulgaria starts after heavy rainfalls, as was evident during the last 20-year wet period. The interconnection between the landslides in Northeast Bulgaria, rainfalls and groundwater maxima is investigated by variations of discharge for spring near Kotel and groundwater levels in two dug wells near Balchik, precipitation from meteorological stations Sofia, Varna, Veliko Tarnovo and Kazanlak, and Palmer Drought Severity Index (PDSI). The periods of maxima of precipitation, PDSI and groundwater time series are compared with the registered occurrence of landslides. Some part of landslides occurs after groundwater maxima, other part – after intensive short-time rainfalls without significant change of groundwater levels. It is necessary to analyze time series of precipitation and PDSI in order to provide comprehensive landslide forecast. The groundwater levels follow almost exactly the PDSI variations, while the short time intensive rainfalls are presented as significant spikes in precipitation time series. The hazard risk of landslides on the territory of Bulgaria should be estimated by the maxima of PDSI, real meteorological data from stations located near the Black Sea coast and inside the territory.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126027964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main principle of the method is to determine the buried structures in the ground by taking advantage of the changes in the vertical direction of gravity acceleration. There are many different methods developed to determine the depth of structures. In this study, the mean depth values of Bouguer gravity data obtained in Dikili district of Izmir province were determined using Radial Amplitude Power Spectrum Method (RAPSM) based on 2D Fourier transform. The greatest advantage of this method over the conventional power spectrum is that it works by determining the mean value of the cross-sections taken in different directions. Thus, it does not matter what direction the user takes the cross section and the depth of the structure can be determined more accurately. As a result of the application, the average depth values of the basement structure of the study area were determined. The topography of the basement structure varies between 320 m and 640 m in the region.","PeriodicalId":134345,"journal":{"name":"10th Congress of the Balkan Geophysical Society","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114357612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
