SOME ASPECTS OF HYDROLOGICAL RISK MANIFESTATION IN JIJIA BASIN

Jijia river basin surface geographically fits in Moldavian Plateau, Plain of Moldavia subunit. Being lowered by 200 to 300 m compared to adjacent subunits, it appears as a depression with altitudes between 270-300 m.Through its position in the extra-Carpathian region, away from the influence of oceanic air masses, but wide open to the action of air masses of eastern, north-eastern and northern continental origin, Jijia basin receives precipitations which vary according to the average altitude differing from the northern to the southern part of the basin (564 mm in north, 529.4 mm in Iasi). A characteristic phenomenon to the climate is represented by the torrential rains in the hot season, under the form of rain showers with great intensity, fact that influences the drainage of basin rivers. Jijia hydrographic basin is characterized by frequent and sharp variations of flow volumes and levels which lead to floods and flooding throughout the basin. The high waters generally occur between March and June, when approximately 70% of the annual stock is transported. The paper analyzes the main causes and consequences of flooding in the studied area, also identifying some structural and non-structural measures of flood protection applied by authorities in Jijia hydrographic basin. As a case study, the flood recorded in Dorohoi in June 28-29, 2010 is presented

CONSIDERATIONS OF THE FOG REGIME IN THE AIRPORTS AREA FROM MOLDAVIA TERRITORY (ROMANIA)

In the airports area where the possibility of frequent mists and lasting fog exist, there is a risk that the aviation activity shut down for hours and sometimes for days. The paper is based primarily on the factual material represented by continually measured data during the 1961-2012 period by the weather stations witch are located in Iaşi, Bacău and Suceava airports area. Of all the airports located on the Moldova territory, the Iasi airport have lowest risk of occurrence of fog (33 days/year), and the opposite, with the highest number of days with fog, is Bacău airport (57 days/year). Annual average duration of fog case is between 5.4 hours at Iași and 8.3 hours at Suceava. In all that three airports, calculations based on long sequences of observations (1961 - 2012) have indicated that the annual number of days with fog presents a downward trend, more pronounced in Bacău and Suceava airports

CHARACTERISTICS OF PRECIPITATIONS TRENDS IN THE AREA OF IAȘI, BACĂU AND SUCEAVA AIRPORTS OVER THE LAST 50 YEARS

Characteristics of precipitations trends in the area of Iași, Bacău and Suceava airports over the last 50 years. The paper is based primarily on the factual material represented by continually measured data during the 1961-2010 period by the weather stations from National Meteorological Administration network witch are located in Iaşi, Bacău and Suceava airports area. The data is summarised in tables and the interpretation is supported by graphs. The statistical-mathematical processing of the climatic data and their graphical representation are the methods through which the corpus of data collected from the weather stations measurements has been developed. Furthermore, both methods were used in the graphical transposition of the results obtained by averaging the data from the three weather stations. In order to establish a trend, we have used the method of sliding averages, on a time series of 10 years, shifted with a year calculated by averaging the values recorded by those weather stations. The trend line has been drawn by using EXCEL. Long-term trends, in 1961-2010 period, of the evolution in the atmospheric precipitation amounts indicates a rising trend for the last 15 years. The average annual number of days with a precipitation of > 20 and 30 mm indicates a shift of the deviations towards the register of values above average, which is argument case in point for the increasing torrential nature of precipitation over the last 50 years in the area of Iasi, Bacau and Suceava airports

Museums and Technology for Value Creation

Purpose The purpose of this study is to identify the pathway that leads to cities to proceeding towards urban sustainability. Design/methodology/approach This study intends to propose a theoretical analysis on the city as sustainable community that drives urban development adopting a smart vision for urban growth. Findings Cities as sustainable urban communities develop smartness as a vision for change understanding and developing the potential offered by information technology reinforcing the community by shaping collaborative governance. Research limitations/implications Cities using information technology as a source for urban sustainability develop smartness to evolve as smart communities following a managerial and organizational view towards sustainability as a source for continuous innovation and change within urban ecosystem. Originality/value Cities identify a sustainability-oriented and community-driven pathway as a vision for continuous change that helps to improve urban competitiveness, innovation and democracy ensuring high quality of life by strengthening the potential offered by technology-enabled and human-centred smartness
