Definition (english only)
Soil erosion consists in the removal of soil material by water or wind. It is a natural phenomenon but it can be accelerated by human activities.

Sediments Soil, sand, and minerals washed from land into water, usually after rain.
Semi-confined aquifer An aquifer partially confined by soil layers of low permeability through which recharge and discharge can still occur.
Sediment: Fine soil or mineral particles.
Side Channel: A flood channel or abandoned stream channel connected to a stream or river at periods of high flow. Serves juvenile fish as rearing habitat and refuge from floods.

Permafrost: Soil or rock that is frozen year-round. Permafrost can be found in many parts of Alaska, northern Canada, and other countries near the Arctic Ocean.
Composting A process whereby organic wastes, including food and paper, decompose naturally, resulting in a product rich in minerals and ideal for gardening and farming as a soil conditioner, mulch , resurfacing material, or landfill cover.
Conservation tillage:the practice of leaving vegetation on fields during idle periods to protect the soil from erosion and trap moisture.
An electrical system for prevention of rust, corrosion, and pitting of metal surfaces which are in contact with water or soil.
Bedrock - the solid rock that underlies the soil and other unconsolidated material or that is exposed at the Earth's surface.
soil composed of fibrous, spongy, partially decomposed organic matter. Peat forms under conditions where decomposition is incomplete, such as in wetlands. Peat is the typical soil of bogs.

Seed bank The population of viable dormant seeds that accumulates in and on soil and in sediments under water.
soil carbon A major component of the terrestrial biosphere pool in the carbon cycle. Organic soil carbon estimates, rather than total soil carbon, are generally quoted.
Each tree absorbs CO₂ from the air and captures the carbon, converting it to wood, roots and soil. If they plant enough trees, that offsets their emissions, and the net balance of emissions is zero.
parts per billion (ppb) A way of expressing the concentration of a substance in air, water, soil or food. A microgram per kilogram is the same as one part per billion.
permeability Describes the ability of rock or soil to transmit water. permeable Describes material or soil that allows the movement or passage of water through it. Compare impermeable.
The rate of infiltration changes dramatically as soil moisture content changes.
Plant growth can be limited by a number of factors, including soil fertility, water, temperature, and carbon dioxide concentration. Lack of carbon dioxide can induce photorespiration, which can destroy existing sugars.

Both types of ash can potentially be spread on the land as a soil conditioner, to help return the mineral content to the soil, however owing to the potentially very high concentration of minerals it is important that this is done with caution.
(1) The sudden movement of soil from one property to another as a result of a flood or a shift in the course of a boundary stream.

The refuse is spread and compacted and a cover of soil applied so that effects on the environment (including public health and safety) are minimized. An industrial landfill disposes of non-hazardous industrial wastes.
It provides guidance on what constitutes a genuine, additional offset credit for the voluntary carbon market in the context of the CPRS, including offsets from increased soil carbon and from other land-based emissions sources.
For example, lead can accumulate in surface soil near a road due to automobile exhaust. As you move away from the road, the amount of lead in the surface soil decreases.
