U.S.-Sri Lanka Cooperative Research: Mathematical Modellingof Fertilizer Pollution of Ground/Surface Water

项目描述：本项目支持斯里兰卡康提基础研究所V.S. Manoranjan与两位斯里兰卡科学家（物理与化学科学系K. Tennakone博士和环境研究系E.I.L. Silva博士）的合作研究项目。他们计划对地下水和地表水污染问题，特别是化肥造成的硝酸盐和磷污染问题进行探索性研究。这项研究将结合实验室测量和实地观察采用数学模型。这些模型将用于描述土壤和水体中污染物的运动，并将使用将在斯里兰卡获得的实验室和实地实验数据进行验证。这些模型将用于预测磷酸盐/硝酸盐浸出，特别是在难以进行测量的地方。范围：该项目支持一位美国应用数学家与斯里兰卡的物理和环境科学家合作，开发和测试一个环境问题模型，该问题不仅影响到美国，也影响到许多发展中国家。化肥浸出对地下水的污染影响到许多供水水源，并导致严重的环境恶化和人类健康问题。这项合作使美国科学家能够获得外国科学家在国外实地研究中收集的数据，并使斯里兰卡科学家能够获得先进的分析建模技术和美国的高级计算设施。它是由INT和数学科学部联合资助的。

Description: This project supports a collaborative research project by V.S. Manoranjan with two scientists from Sri Lanka, Dr. K. Tennakone, Department of Physical and Chemical Sciences, and Dr. E.I.L. Silva, Department of Environmental Studies, at The Institute of Fundamental Studies in Kandy, Sri Lanka. They plan to conduct an exploratory study of the problem of groundwater and surface water contamination, especially with nitrate and phosphorus pollution, from chemical fertilizers. The study will employ mathematical models in conjunction with laboratory measurements and field observations. The models will be constructed to describe the movement of contaminants in soil and water bodies, and will be validated using laboratory and field experimental data that will be obtained in Sri Lanka. These models will be employed in predicting phosphate/nitrate leaching, especially where measurements are difficult to conduct. Scope: This project supports collaboration of a U.S. applied mathematician with physical and environmental scientists in Sri Lanka, to develop and test a model for an environmental problem that impacts many of the developing countries as well as the United States. The pollution of ground water by leaching of fertilizers affects many of the water supply sources and leads to serious environmental deterioration as well as to human health problems. The collaboration helps scientists in the United States by having access to data collected in field studies in foreign countries by the foreign scientists, and helps the Sri Lankan scientists by having access to advanced analytical modeling techniques and to high computing facilities in the United States. It is being funded jointly by INT and the Division of Mathematical Sciences.
