Using the DRAINMOD-N model to study effects of drainage system design and management on crop productivity, profitability and NO3–N losses in drainage water

Autor: R. W. Skaggs, J. W. Gilliam, J. E. Parsons, M. A. Breve

Publikováno v: Agricultural Water Management. 35:227-243

The environmental impacts of agricultural drainage have become a critical issue. There is a need to design and manage drainage and related water table control systems to satisfy both crop production and water quality objectives. The model DRAINMOD-N

DRAINMOD-N, A NITROGEN MODEL FOR ARTIFICIALLY DRAINED SOIL

Autor: J. E. Parsons, J. W. Gilliam, R. W. Skaggs, M. A. Breve

Publikováno v: Transactions of the ASAE. 40:1067-1075

DRAINMOD-N, a quasi two-dimensional model that simulates the movement and fate of nitrogen in shallow water table soils with artificial drainage, is described. Results of sensitivity analyses are presented and model predictions are compared with resu

Simulation of drainage water quality with DRAINMOD

Autor: M. A. Breve, A. T. Mohammad, R. W. Skaggs, J. E. Parsons, J. W. Gilliam

Publikováno v: Irrigation and Drainage Systems. 9:259-277

The design and management of drainage systems should consider impacts on drainage water quality and receiving streams, as well as on agricultural productivity. Two simulation models that are being developed to predict these impacts are briefly descri

Simulating Aldicarb Transport in a Drained Field

Autor: Robert O. Evans, C. L. Munster, J. E. Parsons, R. W. Skaggs, J. W. Gilliam, M. A. Breve

Publikováno v: Transactions of the ASAE. 37:1817-1824

The United States Geological Survey computer model Variably Saturated Two Dimensional Transport (VS2DT) was modified to treat boundary conditions imposed by parallel subsurface drain tubes. The modified model was used to simulate groundwater flow and

Hydrologic and water quality impacts of agricultural drainage∗

Autor: M. A. Breve, R. W. Skaggs, J. W. Gilliam

Publikováno v: Critical Reviews in Environmental Science and Technology. 24:1-32

While some of the world's most productive agriculture is on artificially drained soils, drainage is increasingly perceived as a major contributor to detrimental off‐site environmental impacts. Howe...
