Click to Enlarge Image HISTORICAL BACKGROUND Early Settlement and Empire: According to archaeologists, present-day Bulgaria first attracted human settlement as early as the Neolithic Age, about 5000 B.C. The first known civilization in the region was that of the Thracians, whose culture reached a peak in the sixth century B.C. Because of disunity, in the ensuing centuries Thracian territory was occupied successively by the Greeks, Persians, Macedonians, and Romans. A Thracian kingdom still existed under the Roman Empire until the first century A.D., when Thrace was incorporated into the empire, and Serditsa was established as a trading center on the site of the modern Bulgarian capital, Sofia.

  • Hydrology of Maritsa and Tundzha
    Hydrology of Maritsa and Tundzha The Maritsa/Meric River is the biggest river on the Balkan peninsular. Maritsa catchment is densely populated, highly industrialized and has intensive agriculture. The biggest cities are Plovdiv on the Bulgarian territory, with 650.000 citizens, and Edirne on the Turkish territory, with 231 000 citizens. The biggest tributaries are Tundzha and Arda Rivers, joining Maritsa at Edirne. Within Maritza and Tundja basin, a significant number of reservoirs and cascades were constructed for irrigation purposes, and for Hydro electricity production. The climatic and geographical characteristics of Maritsa and Tundja River Basins lead to specific run-off conditions: flash floods, high inter-annual variability, heavy soil erosion reducing the reservoirs' capacities through sedimentation, etc. The destructive forces of climatic hazards, manifesting themselves in the form of rainstorms, severe thunderstorms, intensive snowmelt, floods and droughts, appear to increase during recent years. After more than 20 years of relative minor floods during wet seasons, large floods started to occur more often since the end of the 90’s. Theses years of absence of large floods resulted in negligence of political action and financial investment for structural and non-structural flood mitigation measures and maintenance of the river bed and its embankments. 1 The morphology of both river systems is somewhat similar: Maritza flows between Pazarjik to Parvomay in a large flat plain where flood expansion would be very large if no dike contained the flows. However these dikes are not very well maintained out of the main cities, which actually protect them in a certain way ; In 2005 the large inundation upstream Plovdiv certainly prevented Maritza from overtopping the dikes in the city ! Downstream Parvomay, the relief becomes more hilly and the flood plains are more reduced in size until the Greek-Turkish borders where the plain becomes again wide and flat.

  • The Political, Economic and Cultural Influences of Neo-Ottomanism in Post-Yugoslavian Countries
    POLSKA AKADEMIA UMIEJĘTNOŚCI TOM XXVI STUDIA ŚRODKOWOEUROPEJSKIE I BAŁKANISTYCZNE 2017 DOI 10.4467/2543733XSSB.17.026.8324 DANUTA GIBAS-KRZAK Jan Długosz University in Częstochowa THE POLITICAL, ECONOMIC AND CULTURAL INFLUENCES OF NEO-OTTOMANISM IN POST-YUGOSLAVIAN COUNTRIES. AN ANALYSIS ILLUSTRATED WITH SELECTED EXAMPLES Key words: neo-Ottomanism, Islamic terrorism, Turkish policy, post-Yugoslavian countries, religious fundamentalism, the Balkans, economic influence, Islamization. An ideology of neo-Ottomanism, which has become part of the Turkish foreign policy in the 21st century, dates back to the period of the rule of the Ottomans in the Balkans. However, it is difficult to distinguish Islamization from the influence of Turkish factors, but other Muslim countries are also active in the Balkans, for example, Saudi Arabia or Iran. In the 21st century, Muslim inspirations in many areas of life are noticed in Bosnia and Herzegovina, Albania, Kosovo, Macedonia, Montenegro, Serbia (and in the strict sense in Bulgaria and Greece). The goal of this analysis was to show expansion of Turkish policy, defined as neo- -Ottomanism, in post-Yugoslavian countries, and its effect in the spheres of political, economic and cultural life. Therefore, the following question must be asked: do Turkish influences contribute to the specific culture of European Islam, of which goal, despite pre- vailing Islamophobia, is to disseminate ideals of tolerance between nations and religions? Does the Turkish capital contribute only to the economic development of post-Yugoslavi- an countries through investments? On the other hand, the reactivation of neo-Ottomanism may contribute to the development of radical tendencies, including religious fundamen- talism, which is, in many aspects, pose a threat to post-Yugoslavian countries.

  • Flood Forecasting System for the Maritsa and Tundzha Rivers
    Flood forecasting system for the Maritsa and Tundzha Rivers Arne Roelevink1, Job Udo1, Georgy Koshinchanov2, Snezhanka Balabanova2 1HKV Consultants, Lelystad, The Netherlands 2National Institute of Meteorology and Hydrology, Sofia, Bulgaria Abstract Climatic and geographical characteristics of Maritsa and Tundzha River Basins lead to specific run- off conditions, which can result in extreme floods downstream, as occurred in August 2005 and March 2006. To improve the management of flood hazards, a flood forecasting system (FFS) was set up. This paper describes a forecasting system recently developed in cooperation with the National Institute for Hydrology and Meteorology (NIHM) and the East Aegean River Basin Directorate (EARBD) for the rivers Maritsa and Tundzha. The system exits of two model concepts: i) a numerical, calibrated model consisting of a hydrological part (MIKE11-NAM) and hydraulic part (MIKE11-HD) and ii) a flood forecasting system. For some basins both meteorological and discharge measurements are available. These basins are calibrated individually. The hydraulic models are calibrated based on the 2005 and 2006 floods. The hydrological and hydraulic models are combined and calibrated again. The flood forecasting system (using MIKE-Flood Watch) uses the combined calibrated hydrological and hydraulic models and produces forecasted water levels and alerts at predefined control points. The system uses the following input: • Calculated and measured water levels; • Calculated and measured river discharges; • Measured meteorological data; • Forecasted meteorological data (based on Aladin radar grid). Depending on the available input the forecast lead-time is short but accurate, or long but less accurate. If one of the input data sources is not available the system automatically uses second or third order data, which makes it extremely robust.

  • Hydrological Modeling of the High Flow in Maritza River Basin in August 2005 Analysis of the Influence of the Topolnitza Reservoir
    HYDROLOGICAL MODELING OF THE HIGH FLOW IN MARITZA RIVER BASIN IN AUGUST 2005 ANALYSIS OF THE INFLUENCE OF THE TOPOLNITZA RESERVOIR Eram Artinian National Institute of Meteorology and Hydrology of Bulgaria – regional centre Plovdiv [email protected] Abstract High waters that streamed down the beds of nearly all rivers of Maritza river basin and especially down the bed of Topolnitza river from the fourth till the seventh day of August 2005 were an event of major influence upon all aspects of life in this region of Bulgaria. They were caused by the extreme amount of rainfall in the areas of Ihtiman, Kostenets, Dolna Banya etc., in the North-West part of the river basin on the fourth and the fifth day of August and in the Rhodopy and the Gornotrakiyska valley regions on the following days. The high water stream itself caused overflow of the rivers Mativir, Topolnitza and Maritza in a number of areas downstream of their river beds and caused substantial material damages and even took away a human life. In the Rhodopi region, the waters of Chepinska, Cherna, Shirokolashka and Chepelarska rivers also caused substantial disruption of their river banks. Supporting walls and other items of infrastructure were pulled down at many places. Large areas of road covering sank down. Considerable material damages were caused in the towns of Smolyan, Velingrad and Chepelare. To find the numerical expression of the approximate flow in the river network near the city of Plovdiv for the purposes of this research, the physical processes in the ground layer of the atmosphere, in the ground – under ground combination and in the river network for the period from the first till the tenth of August were simulated.

Also known in the Turkish historiography as the Sırpsındığı Zaferi this Ottoman victory over a coalition of South-East European rulers (King Vukašin and Despot Uglješa) in the vicinity of Edirne is referred to in the historiographies in the region as an event that initiated the Ottoman conquest of the Balkans. The following study will offer a broad discussion on the sources as well as studies referring to early Ottoman history and the Battle of the Maritsa River. My intention is to bring attention to the great variety of versions that narrate the event. I will discuss how the authors constructed all these visions on the memorable event. By comparing Ottoman, Slavic, Greek and western sources I will discuss how these accounts came into being, the chronology they use, their imagination of the battlefield etc.
