Assessment of radioactive contamination in water bodies around mine workings using radiation counter
The vulnerability of water bodies to contamination within the neighbourhood of open mine cast environ cannot be overemphasized. Evidence of radioactive trace elements associated with the target minerals in the Plateau State (Nigeria) showed the extent of this vulnerability. In order to address this challenge, the radioactivity levels of water samples from mine ponds, streams, wells, and borehol...
abstract although lateral drains play the main role in removal of excess water from soil profile in subsurface drainage systems, but it is assumed that perforated collectors can directly remove a part of drainwater from soils. this part of discharge in subsurface drains is not usually taken into consideration in drainage design criteria, due to lack required information and its difficult estima...
Introduction: Earth's atmosphere contains billion cubic meters of fresh water, which is considerable as a reliable water resource, especially insultry areas. What is important in this context, how to extract the water, in an economic manner. In order to extract water from air conditioner, no need to spend any cost, because water produced as a by-product and trouble production. The aim of study ...
Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...
the intakes usually have been used in water distribution networks, irrigation channels, sewage networks, and the water/wastewater treatment facilities, etc. lack of sediment control entered to the intake channel is the main reason of entering sediments to the installation systems, which makes many problems for different parts. due to suspended particles in water, the facilities used such as pum...
rain-water-harvesting is one of the means by which agricultural production can be increased to meet the growing food demands in all regions. the study indentified the factor affecting rain-water-harvesting technology adoption for irrigation and farmers practice in water harvesting against drought in lowland woreda, eastern hararghe, oromia region. both primary and secondary data were collected ...
