This paper describes how the information of the key indicators for assessing the degree of forest reclamation success in ex coal-mining area was identified. Those indicators were analyzed using the descriptive statistic as well as the discriminant analysis on the basis of biophysical data representing age class of vegetation after reclamation. The main objective of the study was to find out the...
Land reclamation in coastal areas may have a significant effect on local ground water systems. Steady-state analytic solutions based on Dupuit and Ghyben-Herzberg assumptions are derived to evaluate this effect. Two situations are considered, both with ground water flow resulting from precipitation recharge: the coastal aquifer of an extensive landmass and an island. The results show that after...
Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial sugar manufacture wastewater due to high soluble organic compounds in saline-sodic and sodi...
In the article, mechanical composition and type level of salinity meadow-alluvial soils Gijduvan district Bukhara region were determined. According to obtained data, this soil is mostly non-saline, found in layer below 1 meter. The moderate driving layer, but heavy lower layers. different soil-climatic conditions our republic, including determining general properties irrigated Gijduvon region, ...
M. Łucarz, AGH University of Science of Technology, Engineering of Faculty Foundry, Kraków, Poland The paper presents the results of the research on the used moulding sands subjected to mechanical and thermal reclamation at different stages of the process in the foundry. The research on thermal treatment was carried out in an experimental thermal reclamation appliance. The effects of the proces...
Abstract In response to the global food shortage, a large amount of abandoned land in karst areas has been reclaimed as cultivated land, causing severe nonpoint source pollution. Preferential flow-driven soil nutrient transport on slopes remains poorly studied, though it is major factor pollution, responds changes caused by reclamation. We explored characteristics preferential flow differences ...
The reclamation and reuse of wastewater is one of the possible ways to relieve the serious fresh water resource crisis in China. Efficient reclamation treatment technologies ensure the safe reuse of reclaimed water. In order to screen out and evaluate technologies appropriate for reclamation treatment, a great deal of efforts have been brought to bear. In the present study, a toxicity-based met...
Salinization is the main characteristic of soils in arid and semi-arid regions which reduce the agricultural potential ofirrigated lands. Therefore, soil reclamation as well as determination of the leaching requirement for salt control is veryimportant for better plant growth. In this study, the effects of leaching on saline soils of Sistan region, southeast of Iranwere examined using unsaturat...
