Hydraulic transients (also known as water hammer) can seem innocuous in a residential setting, but these spikes in pressure can cause major damage to large pipelines and industrial pipe networks. In this video, we briefly discuss how water hammer occurs and how engineers mitigate the effect.
Expansive soils cause more property damage per year than earthquakes, floods, hurricanes, and tornadoes combined. Expansive soils are a slow-moving geologic phenomenon, which makes them not very news-worthy. However, they still cause a tremendous amount of damage to buildings and the public infrastructure we rely on every day.
A few things that can go very wrong when you put steam in a pipe. We talked about the damaging effects of water hammer, but there’s another state of H2O equally if not more dangerous when put in pipes. In this episode, we’re talking about steam hammer and differential shock.
This course discusses the evolution and role of urban public transportation modes, systems, and services, focusing on bus and rail. It covers various topics, including current practice and new methods for data collection and analysis, performance monitoring, route design, frequency determination, vehicle and crew scheduling, effect of pricing policy and service quality on ridership.
This course will focus on basic technologies for the treatment of urban sewage. Unit processes involved in the treatment chain will be described as well as the physical, chemical and biological processes involved. There will be an emphasis on water quality and the functionality of each unit process within the treatment chain. After the course one should be able to recognize the process units, describe their function and make simple design calculations on urban sewage treatment plants.
Groningen, a province in the northeast of the Netherlands, is experiencing earthquakes due to the extraction of gas. This phenomenon is called induced seismicity. But what is induced seismicity? And how can the risk to life safety and the consequences for the built environment be reduced? The Groningen situation is unique and for this reason, solutions for the built environment cannot simply be copied from abroad. To contribute to a basic understanding of the various topics in this field, knowledge lectures have been developed as Open Course Ware by a large number of scientists and practitioners.
There is more to Surveying and Spatial Information Systems, and Geomatic Engineering than just measurements and calculations, but this book is about calculations. Calculations and plan drawing are a traditional part of surveyors' work and many fields of surveying involve data collection, calculations and presentation of results using computers.
