Regression coefficients and coefficients of determination for discharge
ratings at lower Laguna Madre discharge measurement sites
[equation: Q
= B_{1} + B_{2}V + B_{3}S, where Q is estimated
discharge in cubic feet per second, B_{1}, B_{2}, and B_{3}
are regression coefficients, V is measured velocity in feet per second, and S is
measured stage in feet above (+) or below (-) the mean stage measured during the
hydrographic survey. R^{2}, coefficient of determination (variability in
the measured discharges explained by the equation); n/a, not applicable]
