CIV E 445 - APPLIED HYDROLOGY SPRING 2011 HOMEWORK 3, CHAPTER 2
Problem 3-1
Use Online Penman
to calculate the evaporation rate for the following atmospheric conditions: month of June;
air temperature 18°C;
net radiation 585 cal/cm2/d;
relative humidity 75%;
and wind velocity at 2-m above the surface v2 = 180 km/d.
Problem 3-2
Use Online Penman-Monteith
to calculate the evaporation rate for the reference crop for the following atmospheric conditions:
month of September;
air temperature 16°C;
net radiation 605 cal/cm2/d;
relative humidity 70%;
wind velocity at 2-m above the surface v2 = 160 km/d; and atmospheric pressure 1005 mb.
Problem 3-3
Use Online Thornthwaite method to calculate the potential evapotranspiration during the month of July for a geographic location at 32°N, with the following mean monthly temperatures, in degrees Celsius.
Problem 3-4
The bottom of a certain 300-km reach of a river can be described by the following longitudinal profile:
in which y = elevation with reference to an arbitrary datum in meters; and x = horizontal distance measured from upstream end of reach in meters. Calculate the S2 slope.
