The International Boundary and Water Commission (IBWC) is responsible for maintaining a series of flood-control projects beginning in New Mexico and extending along the Rio Grande’s international border dividing the United States and Mexico. A review by the USIBWC indicates that, over time, the flood-control capability of the levees has been compromised. Recent flood events along the international border, resulting in significant economic damages and loss of human life, emphasized the need for a timely assessment of impacts of potential flood-control failure. Given a short project time line mandated by IBWC and the large geographic extent of the river and floodwaylevee system (stretching from Caballo Reservoir in New Mexico to the Rio Grande’s mouth, near Brownsville, TX.), innovative methods were developed to conduct a rapid and preliminary economic assessment of the flood-control infrastructure.
