The Froude Number Fr is used to characterize a jump. Jurnal Teknik Sipil dan Perencanaan. Study of local scouring characteristics surroundings several bridge pilars forms. Aliran Dalam Saluran Terbuka – Gunadarma menganggap bahwa jumlah debit aliran sama dari masing The research method includes: Abstract The local scouringcharacteristicsuroundings several bridge pillars forms have a different characteristics, some forms of pillars of the bridge are considered optimum when equipped with the data: Approach VelocityPrevious equation is derived from Bernoulli assuming the approach ie upstream velocity is zero.

This oscillates from bed to surface and back, producing waves of irregular period downstreamAvoid in design. The deepest scouring suroundings the pillar beside the point, at the beginning of the first minute to the 20 th minute in a sudden deep scour the riverbed and form of river bed suroundings are the pillars up and down irregularly. May extend for many kilometres in cities. The depth upstream of the gate is 2. Sluice GatesGiven upstream water levelDetermine required gate opening to pass a particular dischargeEnergy principle applies: The slope of the riverbed i are varied, there are three: The flow discharge rate there are five variations: There is a trash screen at the inlet with 12 20mm diameter bars in a 1.


Determine where the hydraulic jump forms. Example 1Considering the previous example on a hydraulic jump, determine the size of the step required to bring the start of the hydraulic jump to the vena contracta after the sluice gate.

Published on Nov View 23 Download 0. Then, for a wide channel: The maximum allowable headwater depth is 2. Baffle blocks are often used to increase energy dissipation. If y2 yconj, the jump moves upstream and may break against the gate. Stilling BasinsIt is often necessary to control the location of a hydraulic jump.

Land was used at material for river bed, and, there are three kinds of value D The forms of pillar studied are two cylindrical pillars, sheet pile and full walls pillar. The study is conducted at the Laboratory of River in Surakarta. Also, the coefficient of discharge Cd can be defined as: The used flume has length of These equations can be used to determine the depths upstream or downstream of a hydraulic jump.

Typical Stilling Basin DesignExpansions and ContractionsVertical ContractionConsidering a vertical contraction, the momentum change between sections 2 and 3 may be written as: The depth upstream of the gate is 5.


Determine the flow through the gate and the horizontal force on the gate. CulvertsDefinitionDesign of culvertsAnalysis of existing culvertsDefinition of CulvertsCovered channel or pipe carrying a watercourse under an obstruction such as a road.

Determine the capacity of the culvert. Various values and formulae for CD, which can vary particularly at low flows when viscosity and surface tension come more into playSubmergenceModular flow is flow when downstream level is too low to affect flow over weir you design for this.

The objective of this study is to find the form of pillars that will generate the most superficial scouring. ExampleFlow enters a channel through an undershot sluice gate. User Username Password Remember me. In the 20 th minute until the end of the stream scouring decreased almost linearly lines are horizontzl. Type varies with flow so multiple analysis required. Locating a Hydraulic JumpThe location of the hydraulic jump is controlled by the downstream depth typically normal depth.

Step-down; use to move jump downstreamHorizontal Expansions and ContractionsSimilar principles apply. Jilid ke 3, Beta Offset, Yogyakarta. The results salurran for each pillar shapes have different characters.
