The presentation topic is harbour dock engineering. It will be presented by Kashif Ali Khan, Izhar Ahmad, and Seyed Bakth Jamal Shah. A harbour provides shelter for loading/unloading cargo vessels and for vessel building, repair, and launching. Harbours are classified as natural, semi-natural, or artificial. Requirements of a good harbour include sufficient depth, secure anchorage, breakwaters, and a wide entrance. Defects like insufficient depth or size can be avoided in planning and design. Harbour planning requires thorough site surveys and consideration of natural phenomena.

? PRESENTATION TOPIC: HARBOUR DOCK ENGINEERING ? GROUP MEMBERS: KASHIF ALI KHAN IZHAR AHMAD SEYED BAKTH JAMAL SHAH
?HARBOUR: ? SHELTERED AREA ? FOR LOADING AND UNLOADING OF CARGO ? VESSELS ARE ALSO BUILT, REPAIR, AND LAUNCH
? CLASSIFICATION: 1. NATURAL HARBOUR 2. SEMI NATURAL HARBOUR 3. ARTIFICIAL HARBOUR
? NATURAL HARBOURS: A?harbor, is a place where?ships,?boats, and barges?can seek shelter from?stormy?weather.

? SEMI NATURAL HARBOUR: Same as natural but harbour needs some artificial and man made construction
? ARTIFICIAL HARBOUR: Harbour having no natural protection but artificial arrangement are made to protect the harbour from storm and wind.

? REQUIREMENTS OF A GOOD HARBOR: ? The depth of a harbor should be sufficient for every type of visiting ships. ? The bottom of harbor should provide secured anchorage to hold the ships against high winds. ? To prevent destructive wave action, break water are provided. ? The entrance of a harbor should be wide enough to provide the easy passage of ships.

? DEFECTS IN HARBOR: ? Depth of water is found insufficient for different ships. ? The size of harbor is found insufficient to accommodate the increased traffic. ? Obstruction ? These defects can easily be avoided at the time of planning and designing.
?SIZE OF A HARBOUR Size depends upon: ?# of ships ? length:275m-300m ? width:30m
? HARBOUR PLANNING ? It should be carried out after collecting necessary information of the existing features at the proposed site. ? Following important facts should be studied.
? A thorough survey of the neighborhood including the foreshore & depths of water is necessary ? Nature of a harbor wether sheltered or not, be studied ? The existance of sea insects & various animals residing at site.
? Natural phenomena¡¯s concerning planning of a harbour are: ? Storms ? Rainfall ? Range of tides ? Maximum & minimum temperatures ? Direction & intensity of wind etc
? SITE SELECTION: ? Following factors play a great role in the choice of site of a harbour. ? 1.Availability of cheap land & contruction material. ? 2.Natural protection from waves & winds ? 3.transport & communication facilities ? 4.industrial development of the locality
? 5.Sea bed,sub soil & foundation conditions ? 6.Avaibility of electrical energy ? 7.Defence & strategic aspects ? 8.trafic potentiality of harbour
? FUNCTIONAL CLASSIFICATION: 1. HARBOR OF REFUGE 2. COMMERCIAL HARBOR 3. FISHRY HARBOR 4. MILLITARY HARBOR OR NAVEL BASE
? HARBOR OF REFUGE: The harbor used for ships in storms or emergency condition. good anchorage and safe and easy access from the sea. e.g: DOVER IN ENGLAND
Horbour & Dock Engineerin
? COMMERCIAL HARBOR: Facilities for loading and unloading of cargo are provided. The may be: 1. Part of bigger complex harbor 2. Independent unit or single commodity harbor. 3. Terminal as oil terminal, coal port.

? FISHRY HARBOR: Provided for fishing crafts and trawlers.
? MILLITARY HARBOR: This harbor is meant for accommodating naval crafts and serves as a supply deport. The layout of this type of harbor is greatly influenced by its location.

? FEATURES OF A HARBOR: 1. Entrance Channels 2. Berthing Basin 3. Break Water 4. Turning Basin 5. Pier Head 6. Wharves 7. Jetties
? ENTRANCE CHANNEL: ? Depth and width are kept more at entrance ? Width depends upon density of traffic and no: of entrances

? BERTHING AND TURNING BASINS: ? Berthing basins are used for the parking of ships ? While turning for the turning of ships
? BREAK WATER: ? The structure constructed to protect harbor from storm waves ? They are generally stone masonry
Horbour & Dock Engineerin
? PIER HEAD: ? The structure provided at the tip of break water ? Such as light house
? WHARVES: ? The structure constructed parallel to the shore or break water, having wide plate form at the top ? Function is to permit berthing of vessel along side for cargo working
? JETTIES: ? Same as wharves ? Used for loading and unloading of cargo ? Made usually from shore towards sea water to prevent silting and dredging to allow free flow of tidal currents
Horbour & Dock Engineerin
? DOCK: ? A dock is dug out and usually has gates so that the water level is kept up even though the tide has gone out. ? A dock is for mooring ships for cargo or passenger exchange, or sometimes repair.
? HARBOR: ? ?A harbour may be natural or partly dug out, or even made with floating materials. It doesn't have gates, but may have a narrow entrance. ? ?Provides safe anchoring or mooring for ships
? PORTS: ? A?port?is a location on a coast or shore containing one or more?harbors?where ships can dock and transfer people or cargo to or from land.
