✨GIS (Geographical Information System)
GIS is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data.
The key word to this technology is Geography.
📌What can we do with GIS?
GIS can be used as tool in both problem solving and decision making processes, as well as for visualization of data in a spatial environment.
📌Geospatial data can be analyzed to determine
▪️The location of features and relationships to other features
▪️Where the most and/or least of some feature exists
▪️The density of features in a given space,
▪️What is happening inside an area of interest (AOI)
▪️What is happening nearby some feature or phenomenon, and
▪️How a specific area has changed over time (and in what way).
📌Some GIS software used in civil engineering
▪️ArcGIS
▪️Global Mapper
▪️AutoCAD map 3D
▪️Maptitude

✨GIS and Remote Sensing✨
The data GIS uses to create maps can come from a virtually unlimited number of sources.
One of the most far-out sources of data for GIS is data obtained by REMOTE SENSING.
Remote sensing is nothing more than collecting data from a distance.
▪️Drones, aircraft, and satellites can all carry sensors that can make maps using various sectors of the electromagnetic spectrum.
▪️Some remote sensors are passive and make use of reflected sunlight, while others project various wavelengths of electromagnetic energy at the target and analyze the reflected signals sensing also provides a detailed analysis of remote locations that may be otherwise inaccessible.

✨GIS APPLICATIONS IN CIVIL ENGINEERING✨
▪️STRUCTURAL ENGINEERING :- By incorporating 3D GIS maps with traditional design strategies, Designs can benefit from past failures.
▪️TRANSPORTATION :- With GIS tools, traffic flow trends can be viewed in conjunction with population changes on the same map at the same time.
▪️TERRAIN MAPPING AND ANALYSIS
▪️WATERSHED ANALYSIS :-GIS can provide graphical and numerical representation of water flow rates, direction, depth, and accumulation — on the same map at the same time. Used in conjunction with terrain analysis and pollution data, engineers can help protect the natural water sources that we all depend on.
▪️ENVIRONMENTAL STUDIES AND IMPACT ANALYSIS
▪️ DIASASTER MANAGEMENT

✨ Cross Drainage Works✨
A Cross Drainage work is a structure carrying the discharge from a natural stream across a canal intercepting the stream.
Canal comes across obstructions like rivers, natural drains and other canals.
The various types of structures that are built to carry the canal water across the above mentioned obstructions or vice versa are called cross drainage works.
📌It is generally a very costly item and should be avoided by:
1)Diverting one stream into another.
2) Changing the alignment of the canal so that it crosses below the junction of two streams.

✨Types of Cross Drainage work✨
📌Cross Drainage work carrying Canal over the Drain [ HFL<FSL ]
▪️Aqueduct
(HFL of drain below canal level)
▪️Syphon Aqueduct
(HFL of drain above canal level)
📌Cross Drainage work carrying Drainage over the Canal [ HFL>FSL ]
▪️Super passage
(FSL of canal is below the drainage level)
▫️Simply a reverse of aquduct structure
▪️Canal Syphon
(FSL of canal is above the drainage level)
📌Cross drainage works admitting Canal water into the Drainage [ HFL=FSL ]
▪️Level Crossing
▪️Canal inlets
▫️Note:
HFL = Drainage water level i.e. High flood Level
FSL = Canal water Level i.e. Full supply Level

लाइफ की लढाई अकेले ही है
बस दुनिया वाले Direction hai
कुछ ना कुछ तू कर पायेगा
खुदपे बस तू भरोसा रखं...
अक्सर करना पडता है इंतेझार
बस करते रहना failure से वॉर...
एक दिन success भी आयेगा
कुछ Difficult नहीं ये दिखलायेगा
कोशिश कर तू बस करते जा....
Success की राह तू चलते जा
तुझमे है कुछ तो बात
बस पकडले खुद का हात
मिलेंगे जितने भी रिजेक्शन्स
होंगे वो Goal के प्रोजेक्शनस्
उस प्रोजेक्शनस् के पथ को आझमा कर
Goal को तू हासिल कर
कुछ ना होता है Impossible
खुदमे ही बनादे word 'I am Possible'
कोशिश कर तू बस करता जा

✨Overlapping or Lap Length✨
Length of bar required to transfer the stress safely.
Or
Overlapping Length or Lap Length is provided for maintain the continuity of bars in order to safely transfer the load from one bar to another bar.
▪️ It depends on the Grade of Concrete, grade of steel and dia of bar.
▪️Due to the limited length of bar, laping of bars is required in a member of more than 12m in length.
As per IS 456-2000
📌LAP LENGTH IN COLUMN
Overlapping length should not be less than 75mm. Lapping should be avoided in tensile zone of construction members. In case of column generally we take 24d – 40d where ‘d’ is dia of bar.
📌LAP LENGTH IN BEAM
In case of beam we generally use 24d for compression zone and 45d for tension zone.
📌LAP LENGTH IN SLAB
In case of slab we use lap length 50d where ‘d’ is dia of bar.
