Traditional Channels The North and South Diversion Channels are examples of traditional channels, or concrete-lined arroyos that move floodwater to the river. The city website has more information about Albuquerque’s Arroyos. Non-traditional Channels The Calabacillas Arroyo is one example of a non-traditional channel built by AMAFCA. Dams and Levees A typical AMAFCA dam contains a principal spillway, which is a pipe under the dam, and an emergency spillway, which is the large channel around the side or over the top of the dam. Dams and other types of detention basins collect floodwater, and release it slowly to prevent downstream damage. AMAFCA dams are capable of fully detaining the one percent (100-yr) storm. A storm greater than that, however, could flow through the emergency spillway, which is a safety valve, and cause some downstream flooding. A levee is like a dam but confines water along a waterway such as a river. Water Quality AMAFCA is also concerned with protecting the quality of water for Albuquerque and its surrounding areas. Structures which catch debris and protect the Rio Grande from pollution are often modeled in the UNM Hydraulics Lab before they are built by AMAFCA. These web pages (West Bluff and North Pino) provide more details on recent AMAFCA models. Drainage Policy Download AMAFCA’s Drainage Policy. (pdf) |
