Low water table meaning
WebExtratidal High Water (XHW) and Extratidal Low Water (XLW) are observed water-level extremes measured above the tidal datum HAT (XHW) or below the tidal datum LAT (XLW). These extremes occur only in the presence of a weather-induced residual water level or ‘storm surge’ (observed water level minus the astronomic tide), a sea-level anomaly … WebWater has a low viscosity, but friction is still a factor. All flowing fluids are always losing energy to friction with their surroundings. Water will flow from areas with high energy to those with low energy. Recharge areas are at higher elevations, where the water has high gravitational energy.
