How does particle size affect water retention?
The soil’s ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.
Which type of soil has more water holding capacity and permeability?
How does particle size and composition of the soil affect its water capacity and rate of erosion within a watershed?
The smaller the pore size, the more energy it takes to remove the water. Soil has an effect on the water cycle by influencing the rate at which water evaporates from or moves into and through the soil to saturated zones or aquifers.
Which soil erodes the fastest?
Poor silt erodes even faster than sand or clay, as the moderately sized, relatively lightweight particles leave space through which water can flow and take them away. Most soils contain a combination of clay, sand or silt; those high in organic matter can absorb water more quickly, reducing erosion.
What are the factors that affect watersheds?
Watershed factors affecting runoff are land slope, shape, soil, and land use. The principal effect of land slope is on the rate of runoff. Runoff will flow faster on a steeper slope. This results in higher peaks at downstream locations.
What are 4 factors that affect runoff?
Meteorological factors affecting runoff:
- Type of precipitation (rain, snow, sleet, etc.)
- Rainfall intensity.
- Rainfall amount.
- Rainfall duration.
- Distribution of rainfall over the watersheds.
- Direction of storm movement.
- Antecedent precipitation and resulting soil moisture.
Why do we need to protect watersheds?
Healthy watersheds provide many ecosystem services including, but not limited to: nutrient cycling, carbon storage, erosion/sedimentation control, increased biodiversity, soil formation, wildlife movement corridors, water storage, water filtration, flood control, food, timber and recreation, as well as reduced …
How can we keep the rivers clean?
All you need to do is follow these 7 ways to help keep lakes and rivers clean and pollutant free.
- Use less water.
- Keep your car repaired.
- Use organic gardening techniques.
- Compost and contain yard waste.
- Deal with household chemicals and medicines properly.
- Go sustainable.
- Don’t litter.
What is role of human in prevention of environment pollution?
Take part in environment conservation drives such as tree planting drives. Use water resources efficiently. Use renewable resources by installing equipment such as solar heaters and using solar cookers. Dispose potentially harmful products such as cells, batteries, pesticide containers, etc properly.
Why should we keep our city clean?
If homes, yards, and public spaces are kept clean and maintained, there is no place for these pests to live. This means fewer illnesses for our loved ones. Do not dump trash into rivers, streams, or lakes. Polluted waterways can be another source of disease.
