Irrigation return flow increases recharge by 10 to 20%, and the importance of return flow depends on percent irritated area.

    When the drainage water quality is such that its potential for reuse is exhausted then this drainage should be discharged to some appropriate outlet. This strategy will conserve water, sustain crop production and minimize the salt loading of rivers that occurs by irrigation return flow (Rhoades a, b, .

Oosterveld et al. () developed a linear model to study the impact of irrigation return flow on downstream water quality and from the results it was observed that 3–5% of return flow was derived from sub-surface drainage. In the present study an irrigation return flow model, developed at the USBR, was used to predict what the effect of a change in irrigation water quality would have on the chemical composition of the deep percolate of a saline-sodic soil.

Analyses of irrigation return flow taking into account land cover and irrigated cropland have shown the impact of heavy rainfall (Jiménez-Martínez et al.,Jiménez-Martínez et al., ). Similarly, numerous studies focused on nitrate leaching show that an excess of irrigation can be the cause of it (Jalali, ; and Wallis et al.

The effect of varying irrigation return flow volumes as a possible explanation for the fluctuations in the mean monthly baseflow TDS content of a tributary in the Breë River Valley (South-Western Cape Province, Rep.

of South Africa) has been investigated. A conceptual computer model was used to simulate the movement of water and solutes in ha of soil in an area where vineyards are.

In irrigated agricultural systems, the most relevant water outflow 65 from agricultural land is irrigation return flow (IRF) which is the water leaving irrigated 66 land as surface or sub-surface.

Recycling irrigation return flow is a water-saving measure that helps to deal with water scarcity for irrigation. The study aims to estimate the reuse potential of irrigation return flow. The impact of irrigation return flow on groundwater and stream water should be assessed to properly manage water quality.

Irrigation return flow originates from irrigation water, which is typically stagnant for a long period of time, and thus, water isotopic compositions and chloride could be inferred to be indicators of irrigation return flow.

The sustainability of water for nursery crop production can also be influenced by water quality and, more specifically, nutrients in irrigation return flow from container nursery surfaces. Shaffer MS, Ribbens RW, Huntley CW () Prediction of mineral quality of irrigation return flow, vol V.

The percent of return flow for this study site is slightly lower than the median of 43 % for all reviewed studies and the percent of delayed return flow-return flow after irrigation has ceased-is.

(1) In some locations, irrigation return flows are subject to other water rights or are required to maintain stream flow.

In these special cases, on-site reuse could be precluded and would not be considered part of the management measure for such locations. In these locations, improvements to irrigation systems and their management should still.

The aim of this study was to improve understanding of (a) the effects of bypass flows due to irrigation on the calibration of SWAT model, (b) irrigation return flow (IRF) and/or drainage generating processes, and (c) N leaching dynamics with simulation of agricultural land management (fertilization, irrigation, and plant species) under.

Kenneth K. Tanji's 78 research works with 1, citations and 5, reads, including: Long-Term Regional-Scale Modeling of Soil Salinity. The first, a high salt rejection, low product yield, was operated on variable quality ( mg/1 TDS) irrigation return water.

In the 7-month investigation period TDS removal efficiencies decreased from 93 percent to 80 percent salt rejection and the product flux decreased from. Water quality of Tiruvallur Taluk of Tiruvallur district, Tamil Nadu, India has been analysed to assess its suitability in relation to domestic and agricultural uses.

Thirty water samples, including 8 surface water (S), 22 groundwater samples [15 shallow ground waters (SW) and 7 deep ground waters (DW)], were collected to assess the various physico-chemical parameters such as Temperature, pH.A reduction in the natural river flow together with a discharge of lower quality drainage water can have severe negative impacts on downstream users, including irrigation schemes.

Habitats both within and alongside rivers are particularly rich, often supporting a high diversity of species.Get this from a library! Research needs for irrigation return flow quality control.

[Gaylord V Skogerboe; James P Law; United States. Environmental Protection Agency. Office of Research and Monitoring.] -- There are a multitude of research needs regarding irrigation return flow quality, but only the specific research needs required to undertake an effective control program are described.
