In the absence of irrigation, water from a water table below the root zone can sometimes sustain crop growth. This study was conducted to determine whether alfalfa grown without irrigation, but in the presence of a water ...

Agricultural drainage development in the form of drainage alone and controlled drainage– subirrigation (CD-SI) has created environmental concerns. The primary concern is increased loading of nutrients, pesticides, and ...

The soils and the climate of the Great Lakes and Cornbelt states dictate that drainage is required to carry out economically viable farming activities. When drained, the soils are very productive and this eight-state region ...

The current procedures for the design of culverts are reviewed. Experiments at LaTrobe University, Bendigo, Australia, indicated that the head-versus-discharge relation under inlet control is slightly different from what ...

A review of literature and summary of research results are presented on the effects of drainage on water quality in North Carolina, South Carolina, Georgia, and Florida. Principal findings from the predominate coarse-textured ...

Least squares (LS) methods are frequently used to determine an optimal unit hydrograph (UH) for a watershed. However, the conventionally used ordinary LS method could potentially produce a UH with unwanted fluctuation among ...

Drainage is an essential land-management practice for growing crops in the Lower Mississippi Valley and Gulf coastal areas. Current crop production and water-management methods pose significant potential for surface and ...
