The law of water balance states that the inflows to any water system or area is equal to its outflows plus change in storage during a time interval. [ 2 ] [ 3 ] In hydrology , a water balance equation can be used to describe the flow of water in and out of a system.
The water balance equation relates the change in water stored within the basin (S) to its input and outputs: = In the equation, the change in water stored within the basin (ΔS) is related to precipitation (P) (water going into the basin), and evapotranspiration (ET), streamflow (Q), and groundwater recharge (D) (water leaving the basin). By ...
Principle: Measures changes in the weight of the lysimeter to determine water balance; Operation: The lysimeter is placed on a scale and changes in weight are recorded over time, allowing for the calculation of evaporation, transpiration, and drainage; Suction Lysimeters Principle: Used negative pressure (suction) to extract soil water for analysis
The manual provides detailed instructions on the audit process, which occurs at three levels a) top-down approach, b) component analysis, and c) bottom-up approach. For top-down approach, all water flow data are collected in order to calculate the water balance between input volume and the sum of consumption and losses.
Example of a surface water balance: An example is given of surface runoff according to the Curve number method. [3] The applicable equation is: Osu = (Rai – Ws) 2 / (Pp – Ws + Rm) where Rm is the maximum retention of the area for which the method is used Normally one finds that Ws = 0.2 Rm and the value of Rm depends on the soil ...

Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
