• Abstract:
  The research team conducted a thorough literature review to provide an overview of the state of knowledge regarding hydrological practices in playa lakes, arid zones, and karst terrains. This involved reviewing a wide range of sources, including drainage design manuals from state departments of transportation, publications from the Federal Highway Administration (FHWA), stormwater design guidelines from various states, cities, and international sources, as well as over 300 research studies published in scientific journals and presented at conferences. The review revealed that while many studies have focused on these regions, few address the specific hydrological challenges these environments pose to infrastructure design. To further evaluate current practices, a survey was conducted with 76 experts from 30 state Departments of Transportation (DOTs), 13 university faculty members, 12 consultants, and 21 other agencies (federal, state, city, and local). The survey received 24 responses, providing valuable insights into the effectiveness of existing guidelines and hydrological modeling approaches. Additionally, follow-up interviews with 2 selected participants, including representatives from DOTs in Kansas, Minnesota, New Mexico, and Virginia, as well as other experts, provided deeper insights into current practices.
