| Summary: | Problems of water pond which occured over the urban indicate that the water
volume which come into drainage exceed the normal capacities from drainage
and there are other factors causing to decrease the capacities of drainage. One
of matter causing increase charge the surface current is precipitation intensity.
Maximum precipitation intensity increase giving major effect to level of water run
off discharge at urban drainage.
Calculation of discharge with the rational method use 3 primary factors, they are
maximum rainfall intensity, wide of area, and run off coefficient. Maximum
intensity from daily precipitation data of year 1950-2005 calculated by using
Mononobe method, while data of wide area got with the direct measurement in
field.
Calculation of water run off discharge from yearly period 1950-2005 maximum
precipitation intensity at Jl.Ir.H. Juanda by using rational method indicates that
the water run off discharge is larger than maximum discharge of existing
drainage dimension which equal to 0.52 m3/s. From that research result the
existing drainage dimension need to be considered, especially for future. |
