Suppose the watershed including the San Marcos river can be treated as a 10- kilometer high saturated atmospheric column covering the entire 412 sq. mi. drainage area. With an adiabatic lapse rate of 6.5 C per kilometer, compute the precipitable water (in mm) for surface temperatures ranging from 0 C to 40 C at increments of 2000 meters (2000 m, 4000 m, etc.) and 10 C (e.g. 0, 10, 20, 30, 40 C). Assume that the surface pressure is equivalent to an air pressure value of 29.83 in. Hg
