geochemical stream sediment survey
Natural sediment particles are not spherical.
The sediment fabric changes gradually along this type of clinoform.
It is an actual three-dimensional structure, backfilled with sediment.
The floodwatersbuilt up sandbanks and infused the river with sediment.
Scientists think such inverted craters form when an impact basin fills with sediment and the material around that sediment gets eroded away.
Floodwaters typically carry heavy sediment loads, and the Indus River (image upper right) is muddy brown.
Seat located above drain; water can't be trapped and sediment can't foul seat.
Nevertheless, sediment continues to pour down from the mountainside because of poorly planned road excavations.
In the 2009 image, the salt lake appears bone-dry, filled with off-white sediment.
The production of carbon dioxide by lake sediment will increase correspondingly, resulting in higher levels of emissions to the atmosphere.
The Mississippi River Delta is speckled with clouds and outlined by a wide border of greenish-tan sediment.
River sediment is a major threat that could undo all the positive effects the dam is supposed to bring.
The breakdown of a portion of this matter by bacteria in the sediment contributes significantly to atmospheric carbon dioxide.
During a recent excursion to this area, I was shocked to see the extent of new mountain roads contributing heavy loads of sediment to these rivers.
They could train farmers to allow the sediment to settle out of the wastewater before using it-thereby avoiding the worst of the faecal matter.
He says up to three-quarters of the island's "body mass" -or sediment-is star sand, and he believes the beach project will help regenerate it naturally.
Gill has been studying animals that lived around that time, using fungal spores preserved in sediment as an indicator of the presence of wildlife.
The weight of a deltaic pile of sediment may be so great as to depress the earth's crust, thus forming a moat around the depocentre.
Recently I bought a copper case with a section of shabby Jian,which there's calcified sediment e's flax moulage on the I think it's true,so I spent 60 Yuan buying please have a look superiors.
The second lower basin would collect the liquid and sediment and the dredge pump would pump the soil soup back to the top to be used on agricultural products once again.
Oceanographer Richard Zeebe of the University of Hawaii, Manoa, and colleagues ran carbon-cycle simulations of the oceans and atmosphere based on the data yielded by the sediment cores.
Some of it became entrained with sand and the sediment coalesced into mats that will stay submerged until they are weathered by the water or spotted by the Coast Guard.
We'll find other pools of oil that are exposed, some of which will be in mousse or asphalt, some of it in the form of liquid oil covered over with sand or sediment.
Based on geochemical technical tests conducted in the Yanzidong ore block, western Yunnan, the authors used the hydrochemical survey as the Grade 3 inspection method for high canyon target areas, and rearranged the methods for routine stream sediment survey and soil survey.
All waste materials, excluding river and pond sediment, shall be segregated into categories covering: excavated material or construction waste suitable for reuse on-site, reclamation or fill, construction waste for disposal at public dump or landfill, chemical waste, and general refuse.
