Flow Control and Design Assessment for Drainage System at McMurdo Station, Antarctica
Runoff at McMurdo Station is driven primarily by the melting of snow and glacier ice. Snowmelt runoff passes through McMurdo via a system of drainage ditches, gullies, and culverts. Ultimately, the snowmelt runoff discharges into Winter Quarters Bay and McMurdo Sound through several discharge points...
