Stream Hydrology is computed in details from Terrain Topography by transforming Transverse marcator data toUniversal Tranverse marcator (UTM) data, Referring to WGS84 origin and directly downloaded from Shuttle RadarTopography Mission (SRTM) without Topo maps. Discharge Location at Bridge is measured from farthest point of theRiver for water discharge at the Bridge location. The environment is 3D CAD, fully compatible to other CAD softwares.

Synthetic Unit Hydrograph is plotted by comparing sum of discharge for 1 hour interval of Time and volume of 1 cm

direct Runoff.

Bridge Deck Analysis by Grillage Technique with Moving Loads for Road and Railway vehicles following variousStandards with I, 2, 3 and up to 10 lanes of Loading.

The Bridge Deck Analysis with any standard or user defined loading is effectively done as below:

For Example, Size of Bridge Deck = 13m. x 12.1m., Length of Bridge Deck = 13m, Width = 12.1m.

Considering IRC Class A Loading, the Span or Length of the Train of Wheel Loads = 18.8m.

Next data in the User Input file is given as:LOAD GENERATION 191 (Total 191 steps of moving at an increment of 0.2 m, generating 191 Load Cases)TYPE 1 -18.8 0 2.75 XINC 0.2 (The X, Y, Z Coordinates at the start of First wheel in each Loading Train andincrement of moving forward in +ve direction of X as 0.2 m by generating a Load case for each increment)TYPE 1 -18.8 0 6.25 XINC 0.2 (The X, Y, Z Coordinates at the start of First wheel of 2

ndLane of Loading)

TYPE 1 -18.8 0 9.75 XINC 0.2 (The X, Y, Z Coordinates at the start of First wheel of 3rd

Lane of Loading)

The 3 Lanes ofTYPE 1 (CLASS A) Load will start moving towards X Direction, the entire 18.8m long train of

wheel loads will pass through the Bridge Deck at an increment of 0.2m in X-Direction, or Longitudinal Direction.

Which is mentioned as XINC 0.2, by repeating the increment191 times, covering the length of 191x0.2=38.2m, which

is more than 18.8 + 13 = 31.8m, ensuring the complete pass of the loading train and is specified as LOAD

GENERATION 191

Loading in Longitudinal Direction:

Before Moving the First Front Wheels of the Loading Train is at the start of the Bridge Deck, where the X Coordinate

= 0.0m and the Last Rear Wheels of the Loading Train is at a distance of -18.8m from the Front wheels, where the X

Coordinate = - 18.8m

Loading in Transverse Direction:

The First Load Train Starts at a distance 2.75m from the Edge of Bridge Deck, where the Z Coordinate = 2.75m., the

Second Load Train Starts at a distance 6.25m from the Edge of Bridge Deck, where the Z Coordinate = 6.25m. and the

third Load Train Starts at a distance 9.75m from the Edge of Bridge Deck, where the Z Coordinate = 9.75m.

Coordinates:

The Start Coordinates of First Lane of TYPE 1 (CLASS A) Load X= - 18.8m, Y = 0.0, Z = 2.75m

The Start Coordinates of Second Lane of TYPE 1 (CLASS A) Load X= - 18.8m, Y = 0.0, Z = 6.25m

The Start Coordinates of Third Lane of TYPE 1 (CLASS A) Load X= - 18.8m, Y = 0.0, Z = 9.75m

Bridge Deck width = 12.1m

Total width of 3 Lane Loading Train = ZCoordinate of Start Wheel of Third Lane of Load + Width of Load = 9.75 +

1.8 = 11.55m

This ensures that the Bridge Deck completely accommodates the 3 Lanes of the Loading Train.
