Speaker 1:        [00:00:30 ] Welcome to spectrum the science and technology show on k a l x Berkeley, a biweekly 30 minute program bringing you interviews featuring bay area scientists and technologists as well as a calendar of local events and news. 

Speaker 3:        Good afternoon and welcome to spectrum. My name is Chase Jakubowski and I'll be the host of today's show. Today we present part two of our two interviews with Robert B professor emeritus of civil and environmental engineering at UC Berkeley. [00:01:00 ] Dr B served as an engineer for the U S Army Corps of Engineers, Shell oil, shell development and Royal Dutch Shell. His work has taken them to more than 60 locations around the world. Has Engineering work, has focused on marine environments, is research and teaching, have focused on risk assessment and management of engineered systems. He is cofounder of the Center for catastrophic risk management at UC Berkeley in part two. Brett swift asks professor B about the California Delta balancing development and environmental conservation and shoreline retreat. [00:01:30 ] Is civil engineering misunderstood 

Speaker 4:        or do people simply have a love hate relationship with the built environment? I think a mixture of civil engineering has been changing, so people's preconceived views in many cases are out of date and it's also low of, hey, when the built in art man bite you, it hurts and [00:02:00 ] hurt, encourages. Hey, there is a big reliance on it though at the same time as well. Yes. Airports, bridges, tunnels, water supply system, sewage supply, large ill NGS. That's our game. We're out of Egypt and Rome. That's where we got our start. And now the new term is infrastructure. Yes. To sort of put all that together into one idea. Yes. [00:02:30 ] Are there landscapes scale projects out there that people should be aware of and cognizant of? Yeah, that are underway or have recently completed? Yes. One we've been watching carefully is location than the other lunch and it's what's called the water works and the reason we zoom in closely is it's an excellent laboratory test bed for a comparable [00:03:00 ] problem we face here in California with aren't California Delta infrastructure systems. 

Speaker 4:        Now the Lens, much more comeback, but it deals with an unforgiving test that's the North Sea. And so they've been learning actually over a period of 3000 years. How would it work in a constructive collaborative way with water? We face the same problem here at home. [00:03:30 ] Often the attention associated with civil engineering projects is due to the tension between environmental degradation and economic gain. Is it possible to have balance when you're doing something on this kind of scale? Answer is yes and it's a term bounce. Nature itself can be extremely destructive to itself. Watch an intense [00:04:00 ] storm attack, a sensitive reef area in the ocean. The tension and it can be constructive if it's properly managed, is we need to develop these systems, some of which need to make money and at the same time we need to ensure that what is being achieved there is not being degraded, destroyed by unintended consequences [00:04:30 ] to the environment. 

Speaker 4:        One of the very good things that happened to civil engineering here at Berkeley is we changed our name. We're known as civil and environmental and that's to bring explicit this tension between built works, the natural works, and for God's sakes, remember we have a planet that we've got to live on for a long time. As engineers, we are still [00:05:00 ] learning how to deal with that tension and particularly when something's on a really large scale, best of intentions going forward, body of knowledge at the time you do the project, how do you know what the environmental impacts are going to be? Those unintended impacts reveal themselves. How do you walk these things back? How do you backtrack from having installed something on a landscape level? That clunky question. [00:05:30 ] That's one of the reasons for my fascination with the Netherlands, but the way I've worked there for a year, complements of previous employer [inaudible] is Royal Dutch Shell, so I was there learning all the dodge had confronted flooding from the North Sea and essentially the approach was built a big dam wall between you and at [00:06:00 ] water, you're on the dry site and it's on wet side. They promptly learned that was not good. The in fact heavily polluted areas that they were attempting to occupy and suddenly a new thing started to show in their thinking called give water room so that today they have actually sacrificed areas back to the open ocean [00:06:30 ] to get water. The room needs to do what it needs today and in the end the entire system has been improved. We've been trying to take some of those hard won lessons back to our California Delta 

Speaker 5:        [inaudible].

Speaker 6:        You were [00:07:00 ] listening to spectrum on k a l x Berkeley. Brad swift is interviewing Bob Bobby, a civil and environmental engineer at UC Berkeley. In the next segment they talk about the California Delta 

Speaker 5:        [inaudible].

Speaker 7:        We've talked about the delta a bit. Do you want to expand on the challenges of the Delta and [00:07:30 ] the downside? 

Speaker 4:        Well, I'll start with the downside. One of the things I used to say in class when I was still teaching here is terror is a fine instructor. Okay. So the downside would be if we had what we call the ultimate catastrophe and it's foreseeable and in fact predictable [00:08:00 ] in our delta, we would be without an extremely important infrastructure system. For a period of more than five years. That includes fresh supply for small cities like Los Angeles and San Diego and small enterprises like the Central Valley Agricultural Enterprise. So the picture makes Katrina New Orleans look like a place [00:08:30 ] story. This is big time serious. You'd say hooky bomb. That's a pretty dismal picture. Why? And the answer is back to this risk crepe. The delta infrastructure systems started back in the gold rush days and we want to add some agricultural plans that we built, piles of dirt that I've called disrespectfully [inaudible]. And then we put in transportation [00:09:00 ] roadways, power supply, electrical power, and then we come up with a bright idea of transporting water from the north side of the delta to the South side of the Gel so we can export orders. 

Speaker 4:        Southern California. Those people need water too. Well, it's all defend it by those same piles or hurt built back in the 1850s it's got art, gas storage under some of those islands and our telecommunications goes through there. [00:09:30 ] Our railroads go through air, so if you lose critical parts, those piles there, you got big problems. We can foresee it, we can in fact analyze, predict it. We've in fact quantified the risk. They are clearly unacceptable. We've talked to the people who have political insight and power. They are interested to the point of understanding [00:10:00 ] it and then they turn and ask, well, how do you solve the problem? Well, at this point we say we don't know yet, but we do know it's gonna take a long time to solve perhaps much like the Netherlands, 50 a hundred years. And you can see a Lee blank because there's a two to four year time window. What's this? 50 to a hundred years. Oh, can you tell me about tomorrow's problem? And tomorrow solutions [00:10:30 ] answer, no, this one's not that. So we've run into her stone wall. 

Speaker 7:        So does it then become something that gets tacked on to all the other things that they want to do with the water? Because there's always a new peripheral canal being proposed. Right? Right. And the north south issue on water's not going away. So for some 50 years solution to happen in California politics, you'd have to have a pretty serious [00:11:00 ] consensus north and south to the shared interests there. Correct. And there's no dialogue about that really? No. Within the state, no. How about within the civil engineering community? Within the state? No. So everyone wants to ignore the obvious threat to the, so the California economy because basically you're talking about have you applied a cost to the a catastrophic event of the Delta failing? 

Speaker 4:        Oh yeah, we thought that. Or Action Katrina, who Orleans [00:11:30 ] ultimately has caused the United States in excess of a hundred bill young as ours. Paul that by five or 10 because just the time extent. The population influence though we're talking about hundreds of billions, trillions of dollars. So the economic consequences of doing nothing or horrible and then you'd say, [00:12:00 ] well, is it possible to fix it? Answer is yes. Well, do you know exactly how? No, we don't. That's going to take time to work through. It also takes key word. You mentioned collaboration. Different interests are involved and we need to learn how to constructively and knowledgeably liberate the signings to say, here's a solution that makes sense to the environmental conscience [00:12:30 ] in the environment. Here's a sens
