To facilitate crop growth excess water should be drained from the rooting zone to allow root development of the crop and from the soil surface to facilitate access to the field. Basically, there are three drainage methods from which the designer can

Long term drainage water salinity of pipe drains is modeled with the advection-dispersion equation for the zone above drain level and stream functions for the zone below drain level. Steady-state water flow is assumed. The model is applied to two exp

Drainage water salinity data from 71 public deep tubewells and 79 pipe drainage units near Faisalabad, Pakistan, were studied. Drainage water salinity of the tubewells and the pipe drains remained approximately constant with time. This was attributed
Drainable Surplus Assessment in Irrigated Agriculture: Field Application of the Groundwater Approach
Publikováno v:
Irrigation and Drainage Systems. 11(1):41-60
To assess the drainable surplus of an irrigated area, a methodology based on a groundwater-balance approach was developed and applied in Schedule I-B of the Fourth Drainage Project near Faisalabad in Pakistan. To determine the seasonal net recharge i

This paper reports on laboratory research on the sediment passage capability through long-throated flumes and broad-crested weirs with which the Froude number in the approach channel does not exceed 0.6 over a distance of about 20 times the water dep
