1. What is the Height of Water Table Above Sea Level?

The height of the water table above sea level marks the elevation of the water table or upper surface of the zone of saturation. It represents the level at which the ground is saturated with water and is an important parameter in hydrogeology and groundwater studies.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h_f = \frac{(\rho_s - \rho_f) \times h_s}{\rho_f} \]

Where:

\( h_f \) — Height of water table above sea level (m)
\( \rho_s \) — Density of seawater (kg/m³)
\( \rho_f \) — Density of fresh water (kg/m³)
\( h_s \) — Depth of freshwater below sea level (m)

Explanation: This formula calculates the height of the freshwater table above sea level based on the density difference between seawater and freshwater and the depth of freshwater below sea level.

3. Importance of Water Table Height Calculation

Details: Calculating the height of the water table above sea level is crucial for understanding groundwater flow patterns, managing coastal aquifers, preventing saltwater intrusion, and planning water resource management in coastal areas.

4. Using the Calculator

Tips: Enter density of seawater and freshwater in kg/m³, depth of freshwater below sea level in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density of seawater?
A: Seawater density typically ranges from 1020-1030 kg/m³, with an average of about 1025 kg/m³.

Q2: What is the density of fresh water?
A: Fresh water has a density of approximately 1000 kg/m³ at 4°C, though it can vary slightly with temperature.

Q3: Why is this calculation important for coastal areas?
A: It helps determine the freshwater-saltwater interface and prevents saltwater intrusion into coastal aquifers.

Q4: What factors can affect water table height?
A: Precipitation, evaporation, groundwater extraction, tidal influences, and geological formations can all affect water table height.

Q5: How accurate is this calculation?
A: The calculation provides a theoretical estimate. Actual field conditions may vary due to geological heterogeneity, tidal effects, and other local factors.
