摘要: An approach to modeling a point source of BOD effluent is presented. This displays the seasonal variability range (bracket) possible outcomes with regard magnitude and location maximum oxygen deficit remaining demand by using hydraulic geometry, discharge, water temperature at two gauging stations situated upstream (Gladewater) downstream (Beckville) from (Longview) in Sabine River, Texas. A stepwise sensitivity analysis indicates degree which temporal spatial fluvial input parameters affects where river enters reservoir (Toledo Bend). Though model produced wide bracket (100 km) for distance occurred during winter, curves diverged distances exceeding that reservoir. The fraction oxygen-demanding waste remained was relatively constant annually Beckville (∼60% 70%), but sin...
