What is negative base flow in hydrograph in hydrology?
Per capita water consumption: Virtual water refers to the water included in the production of everything we eat, buy and wear. Following norms are adopted by government of India rural and urban water supply schemes in 2019: Rural- 55 lpcd Towns without sewerage -70 lpcd Cities with sewers- 135 lpcdRead more

In simple words, base flow is the flow of water under the ground between the precipitation and percolation. If the precipitation and percolation act on base flow it is called a negative base flow. In this case, the base flow is below the line of the depletion curve. Negative base-flow is also calledRead more
In simple words, base flow is the flow of water under the ground between the precipitation and percolation. If the precipitation and percolation act on base flow it is called a negative base flow. In this case, the base flow is below the line of the depletion curve. Negative base-flow is also called as bank storage.
It is also called as a draught flow or groundwater recession. The best floor is also called a fair-weather flow.
In civil engineering point of view, flow is very important for human population sustainability and balance in ecosystems.
Baseflow in the soil are depending upon the following factors:
Evapotranspiration is the main cause to reduce the base flow.
In negative base flow, the seepage of groundwater to the surface water for a very short period is reversed. The depletion curve is the recession curve, which is produced after the effect of groundwater seepage. And when the base flow is below the line of the depletion curve called a negative base flow.
