In the present work are studied the temperature and rainfalls for the Cârcinov valley in the last years (2008-20110) related to a longer period of time and to the modifications of the vegetation under the influence of the anthropic action. For the Cârcinov Valley and also for the entire country, the time gap 2000-2011 was hot on its entire period, being noticed warmer winters that took place with a larger frequency, the earliest springs, the hottest summers with longer canicular periods and with exceeding the absolute thermal maximum at the country level. The predominance of the early springs reflects a proof of the regional climatic changes noticed mainly in this interval. For Cârcinov Valley, a region placed in Cândeşti Piedmont, the relationships between the climatic system and that of the hydrographic networks are very important from the point of view of the characteristics of this region, mainly, for the evaluation of the phenomenon with risks, that appear at the crossing of the two systems (climatic -- hoar-frost, white frost, glazed frost, freeze, fog, blizzard and hydrological -- bed processes and inrushes) This orographic shelter has a very significant preponderance in keeping the temperatures higher inside. In this situation Cârcinov valley is safe from the "invasions" of cold or hot air from the plains mainly due to this orographic dam. The sum of the bioactive temperatures (T over or equal with 50 C) is 3704 and the length of the vegetation period (T over or equal to 100 C) is 3164. These data lead us to the conclusion that within the unit studied, the thermal potential of the area differentiates sensibly and it explains the presence of the clay alluvial brown soils covered with beech forests or beech forests - oak groves, that predominate in the northern part of the area. Due to the lack of interest from the Ocolului Silvic / "Forests Division" in the area or of other private divisions, to take for guarding the forests that were given back, the forests were devastated and long surfaces remained barren, without trees.

    Global climate change is one of the most serious issues we are facing today. While its exact impacts on our water resources are hard to predict, there is a general consensus among scientists that it will result in more frequent and more severe hydrologic extremes (e.g. floods, droughts). Since...
