It can save money in the long run by preventing major repairs and service disruptions, and it can also help ensure the safety and well-being of society. Incorporating digitization and AI-powered 3D mapping into the maintenance and monitoring of underground water infrastructure is an investment in the future of our communities. By using advanced radar technology and AI to create accurate 3D maps of the underground water infrastructure, engineers and contractors can more accurately assess the condition of pipes and identify potential issues before they become major problems.Īdditionally, this technology can help communities prioritize which pipes to replace or repair first based on their condition and age, preventing catastrophic failures and minimizing the disruption of water service to residents and businesses. The issue of aging water infrastructure is not unique to any one community, and it is clear that waiting for pipes to fail is not a sustainable solution.ĪI-powered 3D mapping is a technology that can help communities address this problem. Coincidentally, a few days later, Hoboken declared a state of emergency ( ) after a contractor hit an unmarked main waterline during an excavation. Two days before on a cold winter night, a 100 years old waterline broke in Boston flooding dozens of residences. When I spoke at Boston University in February, one of the students asked, “how does 3D mapping help with the aging water infrastructure?” It was an insightful and timely question. Finally, I use to tell my friends and colleagues “Do not do geophysics with your tongue, do not trash your colleagues, and recognize the hard and honest work even when the results are not what you expect”. You may get surprised at the end of the survey campaign with the real results, good or bad it is just geophysics. The models are just a guide for your survey planning. The models are not unique and the site conditions may differ from the synthetic data. The success in your exploration or NDT survey will depend not only on how good are your models. With the simulated responses and sound experience in the field you can plan your survey extent, line spacing, profile length, frequency, source of energy and then discuss the possible outcomes with your client. Computerized programs will create 1D, 2D and 3D synthetic models using this information. There is nothing wrong on asking your client for the size of the target, the expected depth and other geometrical and physical properties that you will use for testing if your geophysical method will work. FWM applies to all geophysical techniques including GPR, Ultrasonic NDT, Electromagnetic Induction, Seismic, Induced Polarization and so on. In my humble opinion, no matter how many university degrees you hold, how experienced you are in any particular scanning or NDT method, you should run a forward modeling of your site conditions, target dimensions, physical property contrasts and survey methodology to see what responses you will get from your site and target.īy running your FWM before discussing the capabilities and limitations of your geophysical survey with your client, you should avoid unscrupulous and unethical people misleading your clients if the proposed technique and survey methodology will work or not. GPR Forward Modeling - Advantages and Disadvantagesįorward modeling (FWM) is one of the first geophysical methodologies that university professors teach in the university and is the base for understanding how physics, materials, measuring instrumentation and survey methodology work altogether.
