Estimating Exchange Rates of Water in Embayments using Simple Budget Equations. part of Quantitative Skills:Activity Collection
In this exercise students will estimate the volume rate of water inflow and outflow for an embayment using simple water and salt budget equations that capitalize on the concept of steady state and conservation principles. The average volume of water in the bay and the total concentration of salt in the bay water are assumed to remain constant. These budget equations can be solved for water inflow and outflow knowing the rate of addition of fresh water to the embayment and the salinities of the inflowing and outflowing waters. Students will then be asked to calculate inflow and outflow rates for Puget Sound, Washington and the Mediterranean Sea given actual values of fresh water input and salinities of inflowing and outflowing water, and compare their calculations to actual measured values.
