If the soil of the canal bed is porous and coarse grained, it leads to more seepage loss and consequently low duty. If it consists of alluvial soil, the percolation loss will be less and the soil retains the moisture for longer period and consequently the duty will be high. Let, Duty = D (hectares/cumecs), Delta = A meters Base period = B days By definition, One cumec

Traffic lane is the number of lanes of traffic that a traffic engineer plans for bridge or road. It is part of carriageway designated by proper marking and is used to control and guide the driver (typically it is 3.6 m (12 ft). Design lane is the lane designation used by the bridge engineer for live load placement, which 3 m (10 ft). It consists of uniformly distributed load

The law of conservation of dimensions can be applied to arrange the variables or parameters that are important in a given problem into a set of dimensionless groups. The original set of (dimensional) variables can then be replaced by the resulting set of dimensionless groups, and these can be used to completely define the system behavior.

Run-off analysis taking into account physical processes have been able to be carried out due to sophisticated computers. River basin is formed by a flow in a river channel, an infiltration flow and a groundwater flow that have different hydraulic characters. The Bureau of Reclamation has used a method called, "Snow Compaction Method for the Analyses of Runoff from

A cross regulator is a structure constructed across a canal to regulate the water level in the canal upstream of itself and the discharge passing downstream of it for one or more of the following purposes: 1. To feed offtaking canals located upstream of the cross regulator. 2. To help water escape from canals in conjunction with escapes. 3. To control water surface
