The Tulane Institute on Water Resources Law and Policy works to foster understanding of the complex relationship between people and water. We are located in New Orleans, where water surrounds us. This provides us with a unique vantage point on the front lines of water law and policy. We provide law and policy analysis to decision makers and the public to ensure that water and the ecosystems it supports are maintained for future generations while providing for the needs of the people today. We work with a broad spectrum of institutions and individuals to incorporate science, engineering, and resource management practices to meet our society's ecologic, cultural, and economic needs. 


Water management – whether for navigation, flood control, public health, or environmental purposes – is more than a matter of science and engineering. Laws and policies also determine how we manage water. These laws and policies are growing in importance as global warming, imperiled freshwater supplies, and coastal erosion take their toll in Louisiana and around the world. Solutions can only come through a new generation of informed, purpose driven actions. The Institute seeks to find harmony between law and policy, science, and engineering to develop water management solutions that will address these global water issues. The scope of our work makes the Institute a unique vehicle for legal and policy thinking, one that looks beyond the abstract to consider the nuts and bolts of how to make good decisions in time for them to matter.
