Consider the following statements about Bligh’s Creep Theory.i. Creep length is the length of path traversed by percolating waterii. To increase the path of percolation vertical cut-off or sheet piles can be providediii. Loss of head per unit creep length is hydraulic gradientiv. Bligh gave no criteria for the safety of weir against underminingWhich of the following statements are correct?

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. 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... Show more

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.
