Below this point, the creek flows over a highly permeable aquifer and water loss by recharge increases to a maximum rate of 4.4 mm/d, which accounts for ∼65% of the total water discharged to the creek.
These proportions are much higher than the proportion of total annual water discharge as CSO bypass flow (10%).
Although CSO discharges represent 10% of the total annual water discharge (CSO plus treated plant effluent discharges) from the WWTP, CSO discharges contribute 40 90% of the annual load for hormones and WMPs with high (>90%) wastewater treatment removal efficiency.
However, the sum of total grey water discharged from the drain started from 4 AM to 10 PM were 864.76, 749.0, and 712.91 m3 in the monsoon, summer, and winter seasons, respectively.
The total average surface water discharge in the Republic of Korea is, therefore, an estimated 67.1 km³/year, bringing the total renewable water resources to 69.7 km3/year (Table 2).
From the total volume of water discharge coming from various sources (approximately 69.5 billion m3), some 11% comes from Qanats (Motiee et al. 2006).
Data summaries are available for a) fugitive air, b) stack air, c) total air emissions, d) surface water discharge, e) underground discharge, f) releases to land, and g) total releases.
Constraints (7 9) impose the upper and lower bounds on storage, water discharge, and total release.
Opoku-Ankomah (2000) used a lumped model, for the whole of the basin, to compute water vulnerability index using only surface water discharge and total population of the basin.
