I. Important of HS in Civilization **1.1 Definition:Hydraulic structures are anything that can be used to divert, restrict, stop, or otherwise manage the natural flow of water. They can be made from materials ranging from large rock and concrete to obscure items such as: wooden timbers or tree trunks.Social development

II. Historic development of HS**2.1 Ancient Hydraulic structures:- In the past 9,000 to 10,000 years, humans had discovered HS to control flow that serve agricultural development and daily activities.

**The Qanat technology: developed by the Persian people sometime in the early 1st millennium BC and spread from there slowly west- and eastwardSargon II invaded Armenia in 714 BC, he discovered this system

**This Qanat surfacing inFinis from a spring thought to be several thousand years old, calledThe Spring of Solomon. It is thought to have been feeding theSialkarea since antiquity.

**Band-e Amir dam, located 35 km north-east ofShirazon Kor river, the river that has always played an important role in the history of Iranian hydraulic engineering.

The early history of this dam is probably 2500 years old.

III. Classification of HS**

TypePurposeStructure1. Storage To store waterDams, reservoirs, Tanks2. Flow control structuresTo regulate the quantity and pass excess flowSpillways, outlets, gates, valves3. Flow measurement structuresTo determine dischargeWeirs, orifices, flumes4. Diversion structuresTo divert the main course of waterCoffer dams, weirs, canal head works, intake works5. Conveyance structuresTo guide flow from one location to anotherOpen channel, pressure conduits, pipes, canals and sewers6. Collection structuresTo collect water for disposalDrain inlets, infiltration galleries, wells

III. Classification of HS**Others: Coastal and harbor structures; Offshore structures

TypePurposeStructure7. Energy dissipation structuresTo prevent erosion and structural damageStilling basins. Surge tanks, check dams8. Shore protection structuresTo protect banksDikes, groins, jetties, revetments9. River training and waterway stabilization structuresTo maintain river channels and water transportationLevees, cutoff, locks, piers, culverts10. Sediment and quality control structuresTo control or remove sediments and other pollutantsRacks, screens, traps, sedimentation tanks, filters, sluiceways11. Hydraulic machinesTo convert energy from one Pumps, turbines, ram

III. Traditional - sustainable approach in design **Traditional approachModern approach-sustainable approach(Conventional procedure, Mays and Tung, 1992) :

**Green or Eco- friendly structuresConcepts for Sustainable Hydraulic Structures:Sustainability: sustainable water resource development; Stochastic design: input uncertainties to design criteria;Hydrology: must be adequate;Hydraulic structures: resist all loads, be permanent; maintainable, and cost effective;Environment: Systems must comply with the social order, be economical, and natural environment friendly, perpetuity.

Sustainable Urban drainage SystemSUDS is a concept that includes long-term environmental and social factors in decisions about drainage.**(Sources: CIRIA, 2000)

**(Sources: CIRIA, 2000)In practice, SUDS techniques work in the same way as natural processes
