    Results showed that the overall accuracy of remote sensing in detecting soil salinity was %, and 98% in detecting cropped area, which suggests remote sensing is a useful tool to detect soil salinity and to monitor changes in soil salinity. The historical irrigation/drainage data were used to analyze the relationship between changes in soil. Soil salinity is an active and complex part of soil property in arid and semiarid irrigation areas that restricts the sustainability of agriculture production. Knowledge of seasonal distributions and migration of soil salinity is important for the management of agriculture. In this study, three-dimensional (3-D) geostatistical methods were used to construct seasonal 3-D spatial .

Whereas irrigation and drainage are intended to address the shortage and surplus of soil water, respectively, an important aspect to address is also the management of salinity. Plants have a limited tolerance for soil water salinity, and despite significant gaps in our practical knowledge, an impression of acceptable salinities is available for many : Sjoerd E.A.T.M.

Poorly drained soils typically exhibit a water movement pattern whereby water from precipitation and/or irrigation infiltrates a shallow depth of soil. Evaluating Salinity in Irrigation Water. Michael Cahn, Irrigation and Water Resource Advisor. Monterey County UCCE.

The last part of this book focuses on the use of wetlands and agriculture for waste treatment, subsurface drainage, and the WINDS model (Water-use, Irrigation, Nitrogen, Drainage, and Salinity). The theoretical development in these chapters is focused on the algorithms in the WINDS model, which models evapotranspiration and simulates salinity.

The design of irrigation, pumping, and drainage systems using Excel and Visual Basic for Applications programs are explained for both graduate and undergraduate students and practicing engineers. The book emphasizes environmental protection, economics, and.

This report examine the nature of salinity, its effects on crop production, its effects on irrigation water, the effects of watrlogging and drainage, efforts to control salinity, the use of early warning systems, and social and institutional issues posed by salinity to conclude that irrigated agriculture will not only survive but indeed thrive in the proper circumstances and with.

Salinity problems developed, and byha had a serious salinity problem and another were endangered. Prepared by the Water Quality and Drainage Committee of the Irrigation and Drainage Council of the Environmental and Water Resources Institute of ASCE.

Agricultural Salinity Assessment and Management, second edition, considers worldwide salinity and trace element management in irrigated agriculture and water supplies. Sodium Hazard. The sodium hazard of irrigation water is expressed as the ‘sodium adsorption ratio (SAR)’.

Although sodium contributes directly to the total salinity and may also be toxic to sensitive crops, such as fruit trees, the main problem with a high sodium concentration is its effect on the physical properties of soil (soil structure degradation).

systems, irrigation and drainage can be sustained in humid areas with minimal environmental impacts, while enhancing the Nation’s agricultural productivity.

The profitability of irrigation and drainage in humid areas depends on seasonal rainfall, adequate economic returns from crops, and irrigation and drainage expenses. To boost profit. The Hetao Irrigation District (HID) is one of three largest irrigation districts in China, located in upper Yellow River basin ().The HID covers a total area of × 10 3 km 2 and more than 60% are the irrigated land (Chen et al., ).About billion m 3 water is irrigated from the Yellow River every year, with salinity of approximately g/L.

Subsurface drainage water from arid areas always has a higher salinity than the supply water, a higher proportion of Na and Cl, an increased hardness and a higher sodium adsorption ratio (SAR). The higher salinity and higher levels of specific ions often reflect the characteristics of the soil through which the irrigation water has percolated.

The primary method of controlling soil salinity is to permit % of the irrigation water to leach the soil, that will be drained and discharged through an appropriate drainage system.

The salt concentration of the drainage water is normally 5 to 10 times higher than that of the irrigation water, thus salt export matches salt import and it.

The irrigation (and drainage) scheme of the LSIP has been successful in increasing the crop yields of the cultivated lands in 1st, 2nd, and 3th stage irrigation areas. The 4th stage area has partly revealed some alleviations in salinity but in general has reflected some dilemma in terms of the conservation and sustainable use of wetlands.

The irrigation‐drainage interaction is characterized by the function between applied water and deep percolation. Irrigation and drainage are inseparably linked. Since the major irrigated areas are located in arid and semiarid regions of the world, salinity becomes a significant factor in the interrelationship between irrigation, drainage, and.

The drainage requirement for salinity control should be based on leaching requirement, salt balance, and capillary‐rise concepts. This chapter is concerned with these aspects of drainage.

If the calculated extent of leaching is to be obtained, natural or artificial drainage must be adequate to convey the drainage water away from the root zone. 24 percent and irrigation water salinity (EC i) of 2 dS/m.
