Starting from main known parameters and raw data, all calculations carried out will be presented explicitly via tables and graphs (you can use excel/matlab for calculations and plots of the results).

For hydrograph experiment derived and plot:

hyetograph of the excess rainfall,

total flow hydrograph and direct flow hydrograph,

unit hydrograph,

unit hydrograph with duration of 600 sec.

Using the “S” hydrograph method find and draw unit hydrograph with duration of 540 sec.

-Chamber Dimensions : 38 cm²

-Basin Area : 10332 cm²

-Timestep for Chamber Shift : 15 s

-Excess Rainfall Duration : 120 s
