The Kamchatka Peninsula – situated in the Pacific "Ring of Fire" – has 29 active and over 400 extinct volcanoes. Since it is situated in the northeastern extremity of Russia, in subarctic climate,the volcanic landforms are overprinted by the 446 glaciers. This research focuses on the 1^(st) Mutnaya catchment which drains the southern slopes of two active volcanoes: Avachinsky and Koryaksky. Those volcanoes are a permanent threat for the cities of Petropavlovsk and Elizovo, which are the 2 of 3 cities of the peninsula. Hence, most of the studies carried out in the area dealt with the natural hazards and only few focus on landscape evolution. Thus, the purpose of this study was to elaborate a cartographic approach which integrates classic geomorphology with state of the art GIS and remote sensing techniques. As result,different landforms and related processes have been analysed and included in the first general geomorphologic map of the 1^(st) Mutnaya catchment.

Fresh Rivers And Salt Springs:Modern Management And Ethno-Management Of Water Resources In Eastern Romania

The present study aims to evaluate the competition between the modern management and the ethno-management of the water resources from Eastern Romania. The employment of specific hydrological, ethno-archaeological and spatial analysis methods yielded well delimited specific areas, corresponding to the levels of NaCl present in rivers and springs. The waters from the mountainous and piedmont areas of the Carpathians are directly influenced by the presence of salt deposits. The reduced salinity of the larger water arteries is due to the important liquid discharges that dilute the salts. The recent ethno-archaeological investigations that focused on the approximately 200 salt springs which were identified in the sub-Carpathian areas of Moldavia, have highlighted a well-structured ethno-management system. The modern management of the fresh water resources, developed under governmental and local communal financial support, must be continued with increased intensity. Conversely, an involvement into the ethno-management of the salt-water springs must be generally prohibited;only seldomly, in cases of uttermost necessity, can it interfere with the 8.000-years-old ethno-management of these salt-water springs.

Potential Groundwater Pollution Risks by Heavy Metals from Agricultural Soil in Songon Area(Abidjan,Cote d’Ivoire)

The soil samples were collected taking into account the land use in Songon area. The hydraulic conductivity (K) of soils was characterized in-situ when specific yield (Sy), pHw and concentrations of Cooper, Iron, Zinc, Cadmium, Chromium and Lead were measured in the laboratory. Pollution load indices (PLI) were calculated to evaluate the soil contamination levels. The soils were neutral and alkaline (6.7≤ pH ≤ 9.20), permeable (1.9 í 10-5?m·s-1?≤ K ≤ 8.2 í 10-4?m·s-1), with a high specific yield (13.33% ≤ Sy ≤ 33.33%) which can favor the pollutants transfer. The heavy metals (Fe, Cu, Zn, Cd, Cr and Pb) have very high concentrations in soils. The integrated pollution indices (PLI) indicate that almost 70% of Songon soils are moderately contaminated by the investigated heavy metals, with windows presenting high indices of pollution related to the intensive use of fertilizers and pesticides. The establishment of new boreholes in the Songon area should consider these heavy metals, so as to avoid the risk of groundwater pollution due to the physical properties of soils.
