When the ground is saturated, excess water will flow as surface runoff. This occurs when the soil can no longer absorb additional water, leading to the movement of water over the land surface towards lower elevations, such as streams, rivers, or lakes. Surface runoff can contribute to flooding and erosion, as well as transporting sediments and pollutants into water bodies.

What occurs when water sinks into the ground and is not taken up by plant roots?
When water sinks into the ground and is not taken up by plant roots, it can infiltrate deeper into the soil, recharging groundwater or aquifers. If the soil is saturated, excess water may flow laterally to join surface water bodies like streams or lakes, or eventually percolate to underground water reservoirs.
What is water spillway?
A water spillway is a structure used to control the flow of water in rivers, reservoirs, or dams during periods of excess water flow. It helps prevent flooding and allows excess water to be safely discharged downstream.
Distinguish between interception and overland flow?
interception-is the store of water droplets by plant leaves as rainfall occurs; overland flow-describes water which runs downslope in unconcentrated form such as sheet floods,rills and rivulets._by Malcom kahonde
What is mean by saturated hydraulic conductivity?
Saturated hydraulic conductivity is a quantitative measure of a saturated soil's ability to transmit water when subjected to a hydraulic gradient. It can be thought of as the ease with which pores of a saturated soil permit water movement.
How does water flow on ground?
Water flows on the ground by following the path of least resistance, typically downhill or towards lower elevations. Factors such as gravity, slope, and surface material influence the direction and speed of water flow. In urban areas, drains and man-made channels can also guide the flow of water.
What occurs when water sinks into the ground and is not taken up by plant roots?
When water sinks into the ground and is not taken up by plant roots, it can infiltrate deeper into the soil, recharging groundwater or aquifers. If the soil is saturated, excess water may flow laterally to join surface water bodies like streams or lakes, or eventually percolate to underground water reservoirs.
If the surface soil is saturated and precipitation increases what would it be?
If surface soil is already saturated and precipitation increases, there is a higher likelihood of runoff and potential flooding. This excess water cannot infiltrate into the ground and may instead flow over the surface, leading to waterlogging and possibly soil erosion.
When soil becomes saturated during rainfall excess water begins to collect on the surface. What is the down slope movement of this excess water to rivers lakes and streams called?
The downslope movement of excess water that collects on the surface during saturated soil conditions is called surface runoff. This process occurs when the ground can no longer absorb additional water, leading to the flow of water over the land surface and into rivers, lakes, and streams. Surface runoff plays a critical role in the water cycle, helping to transport water from land to bodies of water.
When the ground becomes saturated in a rain storm and the excess cannot be soaked up the water will travel along the ground until it hits a low-lying area or a larger body of water. The water that is?
not absorbed will accumulate on the surface, potentially causing flooding or pooling in low-lying areas, resulting in damage to property or infrastructure. Managing water flow and drainage systems is important to mitigate the impact of excess surface water during heavy rainfall.
What does overland flow mean?
The surface flow is of two types 1. saturated flow, which is caused due to saturation of soil and 2. Hortonian flow, which is caused due to excess rainfall intensity. When the rainfall intensity exceeds the infilatration capacity of the soil, Hortonian flow takes place.
Occurs when excess electrons flow between a cloud and the ground?
lightning
What is the relationship between the water table and the flow of a river?
The water table is the level below the ground where soil and rocks are saturated with water. The flow of a river is influenced by the water table because it can affect the amount of water available to feed the river. When the water table is high, it can contribute to increased flow in the river. Conversely, a low water table may result in reduced flow in the river.
Flowing regolith that is not saturated with water is known?
Glanular flow
What is the purpose of a water drainage pipe and how does it help in managing excess water flow?
A water drainage pipe is used to redirect excess water away from an area to prevent flooding or water damage. It helps manage excess water flow by providing a pathway for the water to flow through, reducing the risk of water accumulation and potential damage to structures or landscapes.
What is water spillway?
A water spillway is a structure used to control the flow of water in rivers, reservoirs, or dams during periods of excess water flow. It helps prevent flooding and allows excess water to be safely discharged downstream.
How does rain affect runoff?
Rainfall can increase runoff by adding more water to the surface of the ground. If the ground is already saturated or impermeable, the excess water cannot infiltrate and will instead flow over the surface, causing runoff. Factors like soil permeability, slope of the land, and vegetation cover can also influence runoff.
What is the relationship between spring and the water table?
A spring will flow when the water table is above where the spring exists. If no moisture replentishes the water table, or aquifier, then the spring will discontinue fo flow.
