The paper presents a description of the course of ice phenomena in three rivers (Rega, Parsęta, Łupawa) in the coastal zone (Southern Baltic) in the territory of Poland. An evident acceleration of the term of decline of ice phenomena has been observed over the period of the last 60 years, varying from 3 to 5 days∙dec-1. The situation caused shortening of the ice season in a range from 3 to 7 days...
Background. Legislation for environmentally protecting surface waters in Poland and the EU is considered a priority because of the large human impact on this environmental feature in both highly industrialised countries as well as those that are agriculturally well developed. The biggest threats are regarded as being sewage arising from economic, industrial and agricultural pollution along with rain...
In the paper were presented the results of study for determination of natural (polonium 210Po, uranium 234U and 238U) and artificial (plutonium 238Pu, 239+240Pu and 241Pu) alpha radionuclides in aquatic environment of Poland and southern Baltic Sea as well as the recognition of their accumulation in marine trophic chain. The obtained results indicated that Vistula and Odra as well as Rega, Parsęta...
Plastic responses of 10 aquatic plant species from 5 rivers and 5 lakes in NW Poland were examined. Chara fragilis, C. delicatula, Potamogeton pectinatus, P. perfoliatus, P. natans, Spirodela polyrhiza, Hydrocharis morsus-ranae, Salvinia natans, Nymphoides peltata and Juncus bulbosus were the subject of research. In the running water of rivers, rhizophytes were generally bigger and they allocated...
Floods in urban areas cause considerable economic losses and affect many people. Measures for flood mitigation in urban areas are primarily of an engineering character, however, existing city infrastructure very often restricts the introduction of appropriate new constructions. The city of Gdańsk is situated at the mouth of the Vistula river, on the area, which forms Vistula delta. It is the most...
The persented study attempts to verify a hypothesis on the tectonic conditions of spring distribution and their yield in the western part of the Lublin Upland. The materials used for comparison consists of satellite lineaments map. The relationship between the location of springs and satellite lineament course has been worked out by means of the PC program NIT. The results of calculations carried...
