Calculate the top width of the weir wall (B’) if the head of the water over the weir wall at the time of the maximum flood is 2 m. Take the specific gravity of the floor material as 2.4.

Seepage Theories topics include: Hydraulic structure failure, bligh’s and lane’s eeighted creep theory, khosla’s theory. Here are some theories of irrigation seepage: Bligh's Creep Theory: This theory states that water percolates along the bottom contour of the structure's foundation. The length of the path the water travels is called the length of the creep. Bligh's Creep Theory is used to design weirs on permeable foundations.

Here are some theories of irrigation seepage:
Bligh's Creep Theory: This theory states that water percolates along the bottom contour of the structure's foundation. The length of the path the water travels is called the length of the creep. Bligh's Creep Theory is used to design weirs on permeable foundations.
Khosla's Theory: This theory states that water seepage moves along a set of stream lines, not along the bottom contour. Khosla's method of independent variables is used to determine pressures and exit gradients for seepage below a weir or barrage.
Lane's Theory: This theory states that seeping water comes out at the downstream end and then travels along a vertical, horizontal, or inclined path. The downstream end is called a hydraulic gradient line.
