13.7. DESIGN OF WEIR
Dimensions of different parts (such as vertical cutoff, impervious floor, etc.) of a weir on a permeable foundation are determined from surface and subsurface flow considerations as discussed in the following sections.
The data required for this purpose include:
(i) longitudinal section and cross-section of river at the weir site,
(ii) stage-discharge relationship including HFL and the corresponding discharge, (iii) characteristics of sediment and river bed material, and

(iv) canal data such as full supply level and the corresponding discharge, canal cross-section, longitudinal section, etc.
