Abstract Weir is a river building designed to meet the needs of irrigation. River containment will result in considerable elevation differences between upstream and downstream weirs and result in hydraulic jumps.
Hydraulic jumps that occur downstream of the weir will cause scouring downstream of the dam to damage the stability of the weir. So that in the planning of weir there is energy damper of stilling basin. Given the complexity and importance of the problems occurring downstream, the study of scouring downstream from weirs due to the influence of flow to river discharge needs to be given special attention, so that later it can be seen the scouring pattern and the scour depth that occurs.
A study on scouring downstream of weirs was conducted in a laboratory with a weir model using a stilling basin vlughter type pond that flowed with three variations of discharge, testing each variation of the flow for 60 minutes.
The experimental results show the greater the flow discharge the greater the scour depth and the flow characteristic values such as the Froude and Reynold numbers.
The sediment transport balance was obtained during observation of scour depth at 50 minutes. With the protection of groundsill provide reduction of scour depth by References Abdurrosyid, J. Chow, VT.

3Experimental And Numerical Modeling Of Flow In A Stilling Basin
A micro fertigation system was designed using local components, simple and easy to build, operate and repair by farmers. Evaluation of hydraulic performances consists oflong-path size in emitters, relationship between discharge and head in emitter, head loss along the lateral, and emission uniformity. The result of the research indicated that the micro fertigation system with 0,5 mm inside diameter micro-tubing used to control the flow from outlets along laterals. The individual microtube was 0,6 m long and spaced at 0,3 m interval along laterals. The coefficient of manufacturing variation, CV was 0, from samples of emitters, and an interpretation of values was excellent. Keywords: micro fertigatian system, hydraulic performance, emission exponent, head loss, emission uniformity. Skip to main content Skip to main navigation menu Skip to site footer.
