EROSION AND SEDIMENT TRANSPORT
MECHANISMS QUESTIONS AND 100%
VERIFIED ANSWERS!!
What historical recognition has been made regarding soil erosion?
The problem of soil erosion has been recognized by our ancestors.
What are some methods developed to cope with soil erosion?
Methods and practices for coping with soil erosion include new technologies for better erosion
control structures achieved through trial and error.
What modern pressures contribute to excessive soil erosion?
Modern agricultural technology, population, and economic pressures introduce new crops,
farming systems, and cultivation on steep slopes.
What is a consequence of excessive soil erosion on soil fertility?
Excessive soil erosion endangers the fertility of soils, leading to reliance on chemical fertilizers.
How does soil erosion affect water bodies?
Soil erosion reduces the storage capacities and water quality of reservoirs and ponds.
What ecosystems are threatened by soil erosion?
The stability of aquatic ecosystems such as lakes, mangroves, and marshes is threatened.
What is necessary for understanding terrestrial ecosystems in relation to erosion?
Engineering, hydrologic, and ecological validation is needed to understand interrelated
parameters and processes.
What hydrologic processes need to be quantified in relation to erosion?
Quantification of hydrologic processes such as soil erosion, sediment transport, and runoff is
necessary.
What are the main actions that cause soil erosion?
, Soil is eroded by wind, water (including ice), gravity, and human activity.
How is soil erosion classified?
Soil erosion is classified based on the media concerned (e.g., wind and water) and descriptive
parameters like magnitude, source, location, and shape.
What are the two major types of erosion?
1. Geological erosion (natural processes) 2. Accelerated erosion (abnormal erosion due to human
activities).
What is the difference between geological and accelerated erosion?
Geological erosion is a natural process, while accelerated erosion occurs at a faster rate due to
human activities, leading to land degradation.
What are the forces involved in soil erosion?
The forces involved are attacking forces and resisting forces.
What are the two interactive processes in soil erosion?
1. Detachment of soil particles from the surface 2. Transport of detached particles.
What is required for significant soil loss to occur?
Both detachment and transport processes must be at work for considerable soil loss to occur.
What can cause soil detachment and transport?
Soil detachment and transport can be caused by water, wind, or any mechanical force applied to
the soil.
Who analyzed the process of detachment and transport of soil materials?
Ellison (1947) analyzed the process of detachment and transport of soil materials by erosive
agents.
What erosive agents are involved in erosion by water?
Rainfall and runoff are the erosive agents involved in erosion by water.
