DESIGN OF TRAPEZOIDAL STORM WATER DRAIN. ( Actual Program is available in  Super Civil CD )
[A] Calculation Of Drain Capacity :
Run off (discharge) [m3/s]
Depth of Drain  [m]
Base Width of Drain  [m]
Side Slope of Drain [ H : V ]	1 : 1 1.5 (H) : 1 (V) 2 (H) : 1 (V) 2.5 (H) : 1 (V)
Slope of Drain [1: S]                                  1:
Drain Construction	Finished Concrete Brick/Stone Work RR Masonry Earthen Drain RR Pitching Natural Stream Rocky Stream
Velocity [m/s]:	AREA of Drain [m2] :
Hydraulic Mean Depth [m] :	Perimeter of Drain :
[B] Calculation Of Run Off :
TRIBUTARY  AREA  [HECTOR]	{1 hector = 10000 m2 }
INTENSITY OF RAIN FALL  [MM/HOUR]
AREA CHARACTERISTICS	PAVEMENTS/ROADS COMMERCIAL AREAS RESIDENTIAL AREAS SCHOOL AREA OPEN SANDY AREAS ROCKY TERRAIN COMPACTED SILTY AREA
