Impact of Climate Change on Irrigation Water Management

These factors will eventually impact to greater uncertainty regarding water supplies and increased water control. Against this background three scenarios were developed through SAPWAT3 (Van Heerden, et al., 2008) to illustrate the expected impact of climate change on the irrigation water requirement of crops in the central parts of South Africa: 1.


Having less water of lower quality is a fact the industry may face. To reduce water consumption and mitigate pollution runoff, horticultural operations may capture and recycle irrigation runoff. The Water Pollution Control Act sets the standard for clean water and prescribes point-discharge requirements for federal, state, and regional water

Research You Can Use Buffer Strips, Runoff, and Leachate

The leachate water samples were analyzed for nitrate- and ammoniacal-N and soluble phosphorus. Runoff samples were analyzed for three P types: soluble P, biologically active phosphorus (BAP), and total phosphorus (TP), which were extracted from both sedi-ment in the water aswell as the water itself Sediment in runoff was collected and quantified.


Surface runoff generally is the main loss with flood irrigation. Surface runoff occurs due to the large amount of water ponded on the soil surface during irrigation. After the irrigation water is terminated or cutoff, the ponded water continues to flow down the field. If the cutoff time (time that the application of irrigation water ends) is

Washington Water Laws - A Primer

Early water law Early in Washington s history, acquiring the right to use water was a fairly simple process. If water was available, anyone could make reasonable use of it. Because water is essential to life, most settlement and human activity occurred close to water. The riparian doctrine of water law allows for the historic rea-

The percentage of irrigation water applied and lost to runoff during the weekly irrigation-induced runoff events averaged 28 ± 8% and 28 ± 2% for the August and September studies respectively (Table 1). In addition to the irrigation-induced runoff events (4 in August and 5 in September), one natural rainfall event occurred during each study.

Water that percolates below the root zone (deep percolation) is lost to crop production, although deep percola-tion may be necessary to control salinity.

urban agriculture can be widely promoted by the municipal authority, the effect on plant growth, sustainability of grey water irrigation (in terms of medium-to-long-term effects on soil quality), community acceptance of the practice, and associated health risks both during irrigation, and as a result of crop consumption, need to be investigated.

Runoff can be calculated using the following relation: R=Kb * P (1) Where, Kb and P are the rainfall and runoff coefficient, respectively. Infiltration The process by which water on the ground surface enters the soil that is governing by two forces: gravity and capillary action are known as infiltration. The water enters the surface starter of

The kinds and quantities of minerals dissolved in surface water of the basin are related principally to the geology of the runoff area and to rainfall

Capturing and Recycling Irrigation Runoff as a Pollution

Capturing and recycling irrigation runoff can eliminate pollution of local water supplies by nurseries. Water availability varies from region to region. For example, in some parts of Texas, water is a limited commodity for growers. Surface water is not as readily available, so water is pumped from deep wells. If the quality of the water is

Shares of irrigation withdrawals from surface-water sources vary from year to year depending on surface runoff and water stored in reservoirs. Surface-water availability in 1990 was below normal in much of the West.6 Ground water is the primary supply source for irrigation in about half of the States in table 2.1.1.

AREI Ch. 2.2 Irrigation Water Management

Water management is an important element of irrigated crop production. Efficient irrigation systems and water management practices can help maintain farm profitability in an era of limited, higher cost water supplies. Efficient water management may also reduce the impact of irrigated production on offsite water quantity and quality.

The limits to the availability of land, and especially of water, necessitate the careful use of these resources, particularly the efficient use of water in irrigation. Irrigation, a human intervention, has a twofold effect on the natural environment:

Technologies Affecting Surface Water Storage and Delivery In the Western States, where demand for wa-ter often exceeds supply, additional surface water can be made available by: 1) increasing the total amount of water in storage, or 2) con-serving existing water supplies.

4C: Erosion and Sediment Control

Water erosion is generally recognized in several different forms. Sheet erosion is a process in which detached soil is moved across the soil surface by sheet flow, often in the early stages of runoff. Rill erosion occurs as runoff water begins to concentrate in small channels or streamlets. Sheet and rill erosion carry mostly
