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

描述：该项目支持V.S. Manoranjan和两位来自斯里兰卡的科学家，K博士。物理和化学科学系Tennakone和E.I.L.博士。斯里兰卡康提基础研究所环境研究系的Silva。 他们计划对地下水和地表水污染问题进行探索性研究，特别是化肥造成的硝酸盐和磷污染。 这项研究将采用数学模型，结合实验室测量和实地观察。 这些模型将用来描述污染物在土壤和水体中的移动情况，并将利用在斯里兰卡获得的实验室和实地实验数据加以验证。 这些模型将用于预测磷酸盐/硝酸盐淋失，特别是在难以进行测量的情况下。 适用范围：该项目支持美国应用数学家与斯里兰卡的物理和环境科学家合作，开发和测试影响许多发展中国家和美国的环境问题模型。 肥料沥滤造成的地下水污染影响到许多供水来源，并导致严重的环境恶化和人类健康问题。 这项合作帮助美国科学家获得外国科学家在国外实地研究中收集的数据，并帮助斯里兰卡科学家获得先进的分析建模技术和美国的高级计算设施。 它由INT和数学科学部共同资助。

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.
