AbstractThe effects of the intensive rainfall episodes in the years 2009 and 2010 in the Kőszeg Mountains were investigated. Channel profiles were constructed at various times during these periods, which were used to describe the channel changes. We measured the length of the incised and filled sections on multiple occasions. We could establish the degree and the direction of the changes using this data. The sediment veneer that developed in the area of Kőszeg town was mapped and its conditions of development were examined. The erosion and accumulation landforms developed during these years were classified and described. These forms are the following: rills, gullies, alluvial fans and sediment veneer. We distinguished and characterised those which had previously formed, but they were changed or increased (the channels). We established the conditions under which the sediment veneer can develop, furthermore those conditions which can increase the chance of the formation of this landform. These conditions are the following: the high density of roads in the catchment areas of valleys leading to settlements, the great thickness of superficial deposit, and the steep slope of the surface of the catchment area. We created theoretical classification of the morphological environment where the development of sediment veneer may happen and identified settlements with structures which promote or prevent the development of the sediment veneer. We determined the probability of the development of the sediment veneer at some settlements in Kőszeg, and suggestions have been given to decrease the chance of the development of this sediment veneer.

The aim of the study is to assess the hydraulic capacity of the sewer network and sewer collector recovery in the urban catchment area of Trnava.The analysis focuses on the evaluation of situations with different precipitation frequencies. Elaboration consists of modeling the current state of the assessed sewer collector B and subsequent loading of this collector by several block rainfalls. Based on the results of the analysis, the recovery of the sewer network proposed.

L’objectif de cet article est de poser un diagnostic d’équité environnementale quant à l’accessibilité aux parcs à Ho Chi Minh Ville (HCMV) pour quatre groupes de population (les enfants, les personnes âgées, les personnes faiblement et hautement scolarisées). Pour ce faire, deux mesures d’accessibilité calculées à partir de la distance réticulaire sont mises en œuvre dans les SIG : la distance au parc le plus proche (proximité immédiate) et la méthode du enhanced two-step floating catchment area (disponibilité en fonction de l’offre et de la demande). Puis, plusieurs modèles de régression sont construits avec, comme variables dépendantes, les mesures d’accessibilité et, comme variables indépendantes, les pourcentages des quatre groupes. Les résultats montrent que l’accessibilité aux parcs est très faible à HCMV : en moyenne, les habitants résident à 1,879 kilomètre du parc le plus proche et on retrouve uniquement 0,286 hectare de parc pour 1 000 habitants dans un rayon de deux kilomètres. De plus, les jeunes enfants subissent une double iniquité avec de plus faibles proximité et disponibilité de parcs comparativement au reste de la population.

Tisza River

The main challenge for mankind has always been to eliminate the borders of its living space, as well as to explore and discover its new faces. Contemporary literature strengthens this postulate. It is the preference of the experts of various fields in spatial analysis is to consider space to be repairable, changeable and organisable. In accordance with this axiom, the five affected countries in the catchment area of the Tisza river (Hungary, Romania, Ukraine, Slovakia and Serbia) worked out an integrated, mutual standpoint to support the problems of the catchment area and to exploit its opportunities with the aim to support transnational cooperation. They laid great emphasis on the existing resources which could become the driving force behind regional development directions. This study contains the summarised outcomes of the TICAD project (SEE/A 638/4.2./X) which was drawn up as a result of cooperation between renowned institutions of the five affected countries within the South East Europe Transnational Cooperation Programme (lead partner: VÁTI, Hungary).
