Abstract

The technology available for the control of sediments, nutrients, and
adsorbed biocides in surface irrigation return flows has been reviewed
and evaluated. Some of this technology could be applied immediately to
reduce sediment and associated nutrient and biocide concentrations in
surface irrigation return flows. Much of the available information
needs to be integrated to develop improved control practices. New ideas
and new control technology are needed. Economic incentive programs are
needed to improve acceptance of control technology. The factors controlling
erosion and subsequent sediment concentrations in surface
irrigation return flows, and how these factors can be managed to reduce
erosion and sediment concentrations are reviewed and discussed. Three
approaches (1) eliminating surface runoff, (2) reducing or eliminating
erosion, and (3) removing sediments and associated nutrients and biocides
from surface irrigation return flows, and control measures for
each approach are discussed. Research and demonstration needs for
improving and developing new control technology are presented. These
include simulation modeling of known erosion parameters, the development
of improved irrigation systems and methods, the design of improved
irrigation water distribution systems, and field management practices.
The need for more information on design and operational criteria for
sediment retention basins is discussed.
