There are many methods for determining hydration status, including monitoring body mass changes, measuring various blood markers, and analysis of urine (urinalysis). An effective and simple way to determine the level of dehydration is to monitor body weight changes.
Hydraulic Head. H is a measure of the mechanical energy that causes groundwater to flow. Hydraulic head (h) can be calculated two ways: 1. the sum of pressure head (h p) and elevation head (z), or h=(h p + z). 2. the difference between the land surface elevation and depth to water, or h=(land elevation-depth to water).elocity of Groundwater Movement Based on Darcy's work, we can estimate the velocity of water or how fast the water is moving between points. Velocity is calculated by using hydraulic conductivity, porosity, and hydraulic gradient.
