WEIR MANAGEMENT AS STRUCTURAL MEASURES FOR FLOOD REDUCTION
TEAM 5 2010
What is weir? Weir formulas?
Research Based Approach
Modelling Based Approach
Small overflow-type dam generally used to increase the level of a river or stream.
I. Villemonte (Villemonte, 1947) formula for sharp crested weirs
II. Honma formula (we use this)
III. Extended Honma formula
Q = 0
Free Flow (we use this for ISIS)
Round Nosed Broad Crested Weir (free flow)
1st Solution – Cut Off the Crest
2nd Solution – Adding Geotextile
3rd Solution – Automated Gate
qsrelated to q, s0, d50
