ABSTRACT

This paper presents an analysis of the flow regime of the Timiş River in Romania. The analysis was based on hydrological data provided by the National Institute of Hydrology and Water Management in specialized publications (hydrological yearbooks or online series). The data were supplemented by personal observations in the field. The following leakage parameters were analyzed: average flow (monthly, seasonal, annual), maximum flow (especially flash floods) and minimum leakage. This paper highlights the link between hydrological parameters and conditioning factors of spatial distribution (characteristics of the geological substratum, relief units, elevation, slope) and temporal variation of flow (in function of type of supply, and variability and variation of climatic conditions).

Abstract

Land-use change is one of the major drivers of global biodiversity loss, its study experiencing continuous development and increasing recognition, influencing main research directions within ecology. Many studies target the negative aspect; however, the modification of the natural environment over centuries and millennia led to the biodiversity, in its broadest sense, we are trying to conserve nowadays within cultural landscapes. This theoretical paper deals with the issue of spatial and temporal variations in extensively managed rural landscapes from Central-Eastern Europe. The constraints of the state of the art and arising challenges for biodiversity management in complex, farmed landscapes of high nature conservation value are discussed, through the example of Transylvania (Romania). The paper argues for the necessity of considering historical perspectives and traditional knowledge in an attempt to understand the current on-site conditions and developing realistic adaptive management strategies with special emphasis on the (traditional) rural communities, representing a key resource for biodiversity conservation

Abstract

In the present paper, we identified landscape typologies in the “Iron Gates” Natural Park from Romania and assessed their dynamic starting with 1990 to 2006. We evaluated the dynamic of landscapes based on land use and land covers changes as extracted from the Corine Land Cover databases. We found no major modifications in the distribution of landscapes, only 4.4% of the study area recording changes. Forestry landscapes have the highest ratio of change (on 1.5% from the total surface of the park), with significant decreases also recorded in landscapes of shrub and rare vegetation, as well as mixed agricultural landscapes. Among the active transformation processes, forestation (on 45% of the modified surface) and agricultural activities (20%) recorded the highest distribution.
