discharge velocity is the quantity of flow that flows through a unit cross sectional area of the soil in a unit time
discharge velocity is used to determine the quantity of flow through soil

Discharge velocity refers to the rate at which water flows through a porous medium, such as soil or rock. Seepage velocity, on the other hand, represents the average velocity of water moving through the interconnected void spaces in the porous medium. While discharge velocity focuses on the overall flow rate, seepage velocity gives a more detailed view of how water moves within the porous medium.
Seepage velocity is the rate at which water moves through soil or rock, typically due to a pressure gradient. Discharge velocity refers to the flow velocity of water in a channel or conduit, such as a river or pipe. Seepage velocity is generally slower than discharge velocity due to the porous nature of the material through which water is moving.
Air can escape from a balloon even when it is tied due to the gradual seepage of air molecules through the rubber material of the balloon. Over time, the pressure inside the balloon decreases as air leaks out, causing it to deflate.
Some common causes of failure of a gravity dam include inadequate foundation design or construction, overtopping due to excessive inflow or inadequate spillway capacity, seismic events, internal erosion leading to piping or seepage, and poor maintenance or aging of the structure. Regular inspections and proper monitoring can help to identify potential issues and prevent failure.
When water is carried into fields in open irrigation ditches, much of it is lost to evaporation, seepage into the ground, and runoff. These losses contribute to inefficiencies in water use and can lead to water scarcity issues. Implementing more efficient irrigation methods like drip irrigation can help reduce these losses.
Some carpet paddings have a webbing or moisture barrier coating on one side. If you're installing over wood floors the moisture barrier goes up to prevent spills from soaking into the padding. If installing over cement below ground level the moisture barrier goes down, against the concrete - to prevent condensation and ground seepage from penetrating through the pad.
