| Abstract/Contents: | "Many western U.S. landscapes can be typified by irrigated areas in turf grasses, shrub beds, trees in turf grasses, and vegetable gardens. The irrigation systems can be typified as sprinkler irrigation systems, or often combination drip and sprinkler systems, with sprinklers used in appropriate turf areas and drip irrigation used in shrub beds. Generally, if these irrigation systems are properly designed, then there is clear distinction with individual laterals irrigating either turf grass or shrub beds. The water for irrigation is often potable but it can be raw water that is continued to be used for its decreed purpose, namely irrigation. In many parts of the country, the demands of landscape irrigation can be nearly 50 percent of the total annual potable water demand. Because landscape demand is seasonal, the peak season water treatment needs are in effect driven by the landscape irrigation. Under drought circumstances, supplies are limited and reductions must be made. Typical drought responses include odd-even day irrigation, a proscribed number of irrigation days per week, or some other, blanket curtailment. Alternatively, many water purveyors increase unit cost and reduce demand in a punitive way. None of these methods take advantage of the drought-resilience or economic value of landscape elements in their 'one-size-fits-all' approach to drought response. Landscapes offer tremendous flexibility to adapt water applications to the severity of the drought and drought response plans can be formulated at various levels that are tied directly to the drought severity. For example, under a moderate drought it may be suitable to simply reduce applications to turf grass. Increasing levels of drought severity result in expansion of the drought response to other areas of the landscape, from turf to shrubs to trees." |
