The contracts are still being negotiated, but the price to farmers in the Westlands Water District is likely to be close to $500 per acre-foot—that is, the amount that it takes to flood an acre of land a foot (30 cm) deep.

合同还在谈判中，不过卖给西部水源地区农民的价格很可能接近每英亩英尺500美元——也就是灌溉一英亩土地一英尺深（30厘米）所用水的花费。

Based on the continuously irrigating model test of brackish water(4.7g·L-1)on the shallow thick-bedded clay parting heavy loamy soil with treatments of different amendments,such as zeolite,phospho-gypsm and so on,the effects of long term brackish water irrigation on the physical and chemical characters of soil and the effects of amendments on the soil of long term brackish water irrigation were all discussed.

结果表明，长期灌溉微咸水有恶化土壤化学性状、物理性状的趋势，土壤表层聚盐、氯钠离子比例提高、土壤初始入渗率逐年降低，短期灌溉还能破坏土壤水稳性团聚体，但施用沸石、磷石膏等适宜土壤改良剂能够起到缓解的效果。

Layout forms of irrigation canal system can be generally classified as three categories: series-wound canal system, equivalent shunt-wound canal system and nonequivalent shunt-wound canal system.

文摘：灌溉渠系的布置形式一般可分为串联渠系、等效并联渠系和非等效并联渠系，对这3种灌溉渠系水利用系数进行了理论研究。

Taking a winter wheat field (4 400 m2) of Jinghai county seed farm as experimental plot,sampling by regular grid with with 10 m ×10 m grids,48 sample points were oriented by GPS receipt machine to analyze soil water content at the depth of 0~20 and 20~40 cm in pri-winter,jointing stage and filling stage of winter wheat.The spatial distribution map of soil water of the winter wheat field using geostatistical analyst model of ARC/INFO was drew.And the spatial variability of soil water in vertical and horizontal direction was analyzed.The results could offer scientific evidence for the deciding of the exact time and quantity for winter irrigation.

以天津市静海县良种场内一块长约110m，宽约40m的冬小麦田作为试验区，采用规则格网采样，按照10 m ×10m设置格网，共设48个采样点，通过GPS手持机进行定位，分别于小麦越冬前、拔节期、灌浆期，利用便携式土壤湿度数据采集器对试验地各个采样点0~20、20~40 cm 2种深度土壤含水量进行了测定，利用ARC/INFO的地统计分析模块绘制了冬小麦3个不同生育期试验区土壤水分空间分布图，并分析了其垂直和水平方向的空间变异特征，以期为确定最佳灌溉时机和灌溉量提供科学依据。

The overriding lesson from history is that most irrigation-based civilizations fail," writes Sandra Postel in her compelling survey of the global water crisis, Pillar of Sand: Can the Irrigation Miracle Last?"
