The mass balance between sediment being transported and sediment in the bed is described by the Exner equation.

Aquatic Animal Health Code

Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semi aquatic life in a marine environment.

Aquatic biota Kuwait states that its claim for loss of aquatic biota includes loss of ecological services provided by the subtidal areas.

Erosion accelerates as the mountains rise, and great volumes of sediment are shed into the rivers, which carry sediment away from the mountains to be deposited in sedimentary basins in the surrounding lowlands.

Bacterioplankton occupy a range of ecological niches in aquatic systems.

As for aquatic fauna, fish varieties are found in abundance.

Three sheets of sediment have been found on top of the lava that lies below the city and, mixed in with the sediment, archaeologists have found bits of animal bone, pottery shards and plants.

Here the river slows considerably, dropping sediment that might otherwise form a river delta.

I ask people sometimes, and they say, I like the aquatic theory!

Many of the true frogs are aquatic or live close to water.

From the Yellow River, over 1.6 billion tons of sediment flow each year into the ocean.

Sorting is also a naturally occurring process that results in the concentration of ore or sediment.

Most of the aquatic life of the bay is concentrated near that region.

Investigation, protection and development of transboundary waters and aquatic animal and plant resources

(iii) Listing, classification and harmonization with the GHS (including list of aquatic pollutants)

In addition, if there are discontinuities between layers in the rock or sediment, seismic waves are reflected.

So back in 1982 I said, Well perhaps the elephant had an aquatic ancestor.

This may reduce the oxygen level enough to kill fish and other aquatic life.

Lakes and rivers were teeming with many species of fish, birds and aquatic mammals.

This resulted in a reduction of the estimated area of oil contaminated sediment to approximately 65 square kilometres.

Generated run off is less erosive and less polluting as crop residues reduce sediment transport into river waters.

Somebody up there is issuing the commandment, Thou shalt not believe in the aquatic theory.

So higher levels of fecal coliform require higher levels of chlorine, threatening those aquatic organisms.

Aquatic insects or water insects live some portion of their life cycle in the water.

Information on toxicity can be provided using data from tests performed on aquatic and or terrestrial organisms. This should include relevant available data on both acute and chronic aquatic toxicity for fish, crustaceans, algae and other aquatic plants. In addition, toxicity data on other organisms (including soil micro and macro organisms) such as birds, bees and plants, should be included when available.

Aggradation is the term used in geology for the increase in land elevation due to the deposition of sediment.

The larvae are not fully aquatic, but spend the daytime in the soil near the water.

Air breathing organisms do not take up chemicals in the same manner as other aquatic organisms.

Bitumen permeates the dirt at the surface or, where thin layers of compost and sediment intervene, somewhat below basement levels.

The pile of debris resulting from the Bonneville Slide blocked the river until rising water finally washed away the sediment.

Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water.

To inspect the fishing of aquatic products, To conduct inspections in order to prevent the marine pollution.

The Ganges river dolphin has been recognized by the government of India as its National Aquatic Animal.

Pursue work to improve further the classification scheme on chronic aquatic toxicity hazards (in cooperation with OECD)

These services include food production and provision of habitats for aquatic invertebrates, fish, benthic infauna and plants.

It doesn't matter what kind of sediment you're using to grind up, whether it's bacteria or any other plants or animals.

The analysis revealed there was only one layer of impact debris in the sediment, which indicated there was only one impact.

Marine and inland production According to the Food and Agriculture Organization (FAO), the world harvest by commercial fisheries in 2010 consisted of 88.6 million tonnes of aquatic animals captured in wild fisheries, plus another 0.9 million tons of aquatic plants (seaweed etc.).

Breathing One problem that aquatic insects must overcome is how to get oxygen while they are under water.

Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land).
