Determination of theoretical flood waves, commonly known as hypothetical waves, is still a difficult problem to be solved. Most frequently hydrological modelling is used for this purpose. However, there are no methods for verifying the obtained calculation results. The assumption applied, that daily precipitation with a defined height difference probability triggers off a theoretical wave with the...
During the 2010 flood in the Odra basin a measuring campaign was executed that produced a set of data on peak discharges. Flow measurements located near gauging stations were taken from a boat with an Acoustic Doppler Current Profiler (ADCP) equipped with a GPS. The paper presents a detailed analysis of the records, including referencing to ortophotomaps, to assess the quality of ADCP recording, local...
The synoptic analyses of two different tornado cases, observed in Latvia and Poland in the summer of 2012, are examined in this paper. The first of them, the tornado in Latvia seemed to be a “textbook example” of tornado occurrence. Its development took place in the contact zone of the warm, tropical air, characterized by a very high CAPE (Convective Available Potential Energy), with cold and moist...
Proper environmental project management is a significant element in shaping a positive, pro-environmental image of urban agglomerations and adjacent towns. Environmental resource management and protection, as well as spatial planning in accordance with sustainable development principles, are the most important factors in creating a positive image of, and strategies for, cities. An example of a large,...
This article is devoted to the use of a mathematical model of a flood runoff for calculating rainfall runoff hydrographs from small catchments of the northwest coast of the Black Sea. The described model was tested and applied for the following catchments located in various geographical conditions, with various amounts of initial data: experimental catchments in Zacarpathian, the northwest of the...
Salinization of groundwater is a major problem, particularly in areas with limited infrastructure. 14 diffusion reactors are operated diabatically at -8°C to 20°C to determine the amount of NaCl removed by n-Fe0. The reactors establish NaCl removal by Fe0: (i) 44,000-77,000 nm particle size (PS) = 0.0675-0.1925 g L-1 [feed water (FW) = 0.89 g L-1]; (ii) 50 nm PS = 0.953-1.14 g L-1 [FW = 1.095-1.19...
