The Effect of Drainage Works within the Turu-Lung Somes-Barcau Zone,egrees of glaciation, are prevailing..These works allowed for taking back into culture of a surface of 200,000 ha..The paper proposes to present both the effect of these works on the environment, as well as the different ways of increasing the productivity of clayey soils.

Tubewell-Spacing Formulas for Subsurface Drainage,Well-spacing formulas are not commonly used in practice. For example McCready (1978), reviewing various drainage techniques by wells, does not mention well-spacing formulas.

Area Reduction Factors for Land Drainage Design in Flat Basins in Moderate Temperate Climates,High values of specific discharges from a drainage basin (= discharge per unit basin area, e.g. expressed in m..s.. km. or in 1.s..ha.) generally tend to decrease somewhat with increasing size of the basin. This phenomenon is explained as being due to:

,Integrated Drainage Systems for an Alluvial Wet Land — A Case Study,Waterlogging in alluvial fans or valley bottoms is caused due to very slowly moving body of ground water, which is fed by springs, surface streams or subsurface percolation around the perimeter of the valley; and by surface runoff or infiltrating rainfall on the area itself.
