Some sheets of the 1864 topographic map of South Romania were geo-referenced in order to be co-analyzed with satellite-based 2006 flood inundation map of the Bechet area (Dolj County, Romania). The rectification was based on the corners of the old map sheets as control points, using the previously gathered metadata (geodetic datum and map projectio...

The satellite-based inundation maps of the 2006 Danube floods in Romania were fit geometrically to the 1864 topographic map sheets covering the Romanian regions of Oltenia and Muntenia. The old maps were systematically geo-referenced using the data of the original geodetic control and cartographic details; their Cassini-Soldner projection was prope...

The advantages brought by high resolution satellite data in activities related to flood mapping and flood monitoring are well know in the scientific community. The paper aims to prove that slighter older geospatial documents, such as historical maps, are also a valuable resource for cartographers and decision makers to achieve a better understandin...

The use of remote sensing and GIS techniques for rapid mapping and monitoring is an important tool of information for decision-makers. In 2005 and 2006, the worst floods in the last 40 years affected several regions in Romania. In this paper, we describe the methodology used to map the flood-affected areas. MODIS TERRA and AQUA images were acquired...

Floods are the major disaster affecting many countries in the world year after year. From Romania perspective, floods are among the most hazardous natural disasters in terms of human suffering and economic losses. Major floods occurred in 2005, 2006 and 2008, the worst ones in more than 40 years, have affected large regions of Romania: in the Timis...

In the latest years floods and accompanying landslides, occurred quit frequently in Romania, some of which isolated, others-affecting wide areas of the country’s territory. One region, which suffers from flood damages on a regular basis, is the transboundary area of the Crisul Alb, Crisul Negru and Ko˝ro˝s River. An important objective of the NATO...

Air quality is a major issue for all the important cities in the world. Bucharest is no exception. The air pollution in Bucharest, due to traffic and industry, is abundant, especially in areas the human population is concentrated. The fast rate of economic growth is bringing more sources of air pollution. In this context, the AIRAWARE project, fund...

Abstract The MODIS snowcover product is one of many geophysical products derived from MODIS data. A cross-validation of the MODIS snowcover daily products with data obtained from the meteorological network stations was conducted for the entire territory of Romania. The validation time interval covered the period between 29 October, 2004 and 1 May,...

SUMMARY An accurate monitoring of snow cover extent (SCE) is an essential goal for the scientific research of the Earth Systems. The MODIS Snowcover product is one of the many geophysical products derived from MODIS data. The improved spatial resolution, snow/cloud discrimination capability and global coverage of the MODIS allow a significant impro...

The surveillance and management of water resources in the Carpathian basin of Romania involve the knowledge of snow pack evolution and the snow cover water equivalent estimation in different phases of the snowmelt-runoff season. The paper describes the practical methods developed in the Remote Sensing and GIS Laboratory of the National Meteorologic...

The alpine snow cover in the mid-latitudes is important in risk management, climatic and hydrologic context. An accurate mapping of snow cover and estimation of snow characteristics requires snow to be distinguished from other surface cover and from clouds. In order to become useful, this information about snow extent, have to be provided on regula...

Water resources management in Romania requires a permanent surveillance in space and time of the snow cover, one important natural water resource. The orbital remote sensing represents a viable technique, being able to supply snow observations and measurements at the level of a hydrological basin or for larger areas. The remotely sensed data are pa...

The first snow observations concerning avalanche risk started in Romania in february 2004. The analyzed area covered Bucegi, Piatra Craiului and Fagaras mountains, the massifs most frequented by tourists. One year later, in 2005, was realized the first avalanche risk bulletin; the activity is still "experimental" due to the lack of an avalanche cad...
