Abstract


Drainage affects a host of biophysical soil properties and strongly influences crop growth and quality. Drainage systems improve field operations, enhance growing conditions for crop production and increase crop yields on poorly drained soils. The main problems which lead to a perceived need to cover a drain are: (i) to minimize the adverse impact of a polluted drain, especially close to residential areas, (ii) need to use the land area occupied by the drain for an access road or some other use, (iii) poor soil stability leading to bank failure, and (iv) to protect them from pollution. The concrete pipes or box sections are used for drain covering.
In this study twenty drain coverings were selected and redesigned as pipe and box types with full and partial flow using Darcy and Hazen-Williams equations. Hydraulic and economic studies were carried out to evaluate these coverings. The best alternative for each covering was chosen from the hydraulic view point, the economic view point and from both the hydraulic and the economic view points together
