Surface runoff and tile drainage transport of phosphorus in the midwestern United States.

Journal of Environmental Quality, 2015
The midwestern United States offers some of the most productive agricultural soils in the world. Given the cool humid climate, much of the region would not be able to support agriculture without subsurface (tile) drainage because high water tables may ...

AN OVERVIEW OF DRAINAGE AND SALINIZATION PROBLEMS OF IRRIGATED LANDS

Irrigation and Drainage, 2019
The development of irrigated agriculture is essential to feed the growing world population. Nevertheless, without proper drainage provisions, this development can result in salinization and rising groundwater table problems in irrigated areas.

Drainage‐basin characteristics

, 1932
Factors descriptive of a drainage-basin as related to its hydrology may be classified broadly as: (1) Morphologic—These factors depend only on the topography of the land forms of which the drainage-basin is composed and on the form and extent of the ...

Endoscopic ultrasonography‐guided transmural drainage of walled‐off pancreatic necrosis: Comparison between a specially designed fully covered bi‐flanged metal stent and multiple plastic stents

Digestive Endoscopy, 2017
Endoscopic ultrasonography (EUS)‐guided drainage of walled‐off necrosis (WON) may be carried out by placement of multiple plastic stents (MPS) or specially designed fully covered bi‐flanged metal stents (BFMS).

Acidic Mine Drainage: The Rate-Determining Step

Science, 1970
The rate-determining step in the oxidation of iron pyrite and the formation of acidity in streams associated with coal and copper mines is the oxidation of ferrous iron. Effective pollution abatement necessitates control ling this reaction.
