What are some problems when water runs off over the surface?

What are some problems when water runs off over the surface?

Surface runoff can cause erosion of the Earth’s surface; eroded material may be deposited a considerable distance away. There are four main types of soil erosion by water: splash erosion, sheet erosion, rill erosion and gully erosion.

What are the factors that affect seepage?

seepage, in soil engineering, movement of water in soils, often a critical problem in building foundations. Seepage depends on several factors, including permeability of the soil and the pressure gradient, essentially the combination of forces acting on water through gravity and other factors.

How does erosion affect water quality?

The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

What are the factors responsible for slow surface runoff and replenish underground water?

Forest and other vegetation cover slow the surface runoff and replenish underground water. Sprinklers effectively irrigate the area by checking water losses through seepage and evaporation.

What is run off what are the factors that affect the run off from a catchment area describe the methods of computing run off from a catchment area?

The more the rainfall, the more will be the runoff. Runoff depends on the type of the storm causing precipitation, and also upon its duration. Runoff also increases with the intensity of rainfall and with the extent of the storm over the catchment. Thus, the runoff will be less.

What are the factors affect seepage and runoff?

Meteorological factors affecting runoff: Rainfall intensity. Rainfall amount. Rainfall duration. Distribution of rainfall over the watersheds.

What happens when it rains too much water?

When a lot of rain falls in a short period of time, much of the water is unable to soak into the ground. Instead, it runs over the land. Gravity causes the water to flow from higher to lower ground. As the runoff flows, it may pick up loose material on the surface, such as bits of soil and sand.

What happens when water flows over a slope?

Lesson Summary Water flowing over Earth’s surface or underground causes erosion and deposition. Water flowing over a steeper slope moves faster and causes more erosion. How water transports particles depends on their size. When water slows down, it starts depositing sediment, starting with the largest particles first.

How does the speed of water affect erosion?

The ability to erode is affected by the velocity, or speed, of the water. The size of the eroded particles depends on the velocity of the water. Eventually, the water deposits the materials. As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited.

What happens to particles when water flows faster or slower?

Flowing water erodes or deposits particles depending on how fast the water is moving and how big the particles are. Faster-moving water has more energy. Therefore, it can carry larger particles. It can carry more particles. What causes water to move faster?
