Key Equations

$$c = \sqrt{gh}$$
$$E = \frac{1}{2}\rho g \eta^2 \cdot \lambda, \quad \text{Energy flux} = E \cdot c = \frac{1}{2}\rho g \eta^2 \lambda \sqrt{gh}$$
$$\frac{H_2}{H_1} = \left(\frac{h_1}{h_2}\right)^{1/4} \cdot \left(\frac{b_1}{b_2}\right)^{1/2}$$
$$H_2 = 1 \text{ m} \times \left(\frac{4000}{10}\right)^{1/4} = 1 \times 4.47 \approx 4.5 \text{ m}$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
