Water resources are very important to humans and ecosystems. Only 2.5% of the Earth's water is freshwater, and less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere but 70% of the freshwater used by humans goes to irrigation and agriculture to ensure enough food is produced. Due to large population growth and climate change, the common past perception that water was an infinite resource is no longer valid. In reality, many countries (including California in the U.S.A.) are facing a water crisis. Our industry partner InteliRain Inc is at the forefront of innovations in designing high efficiency sprinkler system which is capable of applications to large landscapes. The developed system produces excellent uniformity distribution and uses less water compared to most existing standard industry system. However, the performance of the InteliRain system deteriorates significantly when it is tested in open field with wind. The goal of this project is to work with our industry partner to improve the sprinkler design so that the attractive features are retained in the presence of wind condition. The project will make a contribution to the sustainable management of water resource, and helping the irrigation and agriculture industry in Alberta and Canada to find better ways to use water more efficiently.

水资源对人类和生态系统都非常重要。地球上只有2.5%的水是淡水， 而河流、湖泊和大气中的淡水不到0.3%，但70%的淡水被 人类通过灌溉和农业来确保生产足够的粮食。由于人口的大量增长 以及气候变化，过去普遍认为水是无限资源的看法不再有效。在……里面 现实中，许多国家(包括美国的加利福尼亚州)正面临着水危机。我们的行业合作伙伴 InteliRain Inc.在设计高效喷水灭火系统方面走在创新的前沿，该系统能够 在大型景观中的应用。所开发的系统产生了良好的均匀分布和使用 与大多数现有的标准行业体系相比，用水量更少。然而，InteliRain的表现 当系统在野外受风测试时，系统的性能会显著恶化。这个项目的目标是工作 与我们的行业合作伙伴一起改进喷头设计，以便在 有风的情况。该项目将为水资源的可持续管理做出贡献。 资源，并帮助艾伯塔省和加拿大的灌溉和农业行业找到更好的使用方法 更高效地用水。
