An outfall discharges 0.8 m3/s containing 1 f i / m 3 of *%s. The cross stction of the outfall channel is rectangular, 2 m wide and 0.5 m deep. The receiving water is 10 m deep and is .ssumcd to be stagnant. The ambient water temperature is 10C d the discharge temperature is 17C. Estimate the size of the near-field zone d the '%s concentration at thc edge of the near field. solve the problem for the case that the depth d the receiving water is 2.5 m. Also, what is the extent of the near-field and %s concentration at the transition distant when there is an ambient crossflow of 0.5 m/s?
