This paper presents a new and alternative method (in the context of urban drainage) for probabilistic hydrodynamical analysis of drainage systems in general and especially prediction of combined sewer overflow. Using a probabilistic shell it is possible to implement both input and parameter uncertainties on an application of the commercial urban drainage model MOUSE combined with the probabilis...

In this paper a multijoint robot f o r sewer inspection tasks i s presented. In order t o increase the operating scope the robot has been made able t o run round or over obstacles, to follow sewage branches and is aimed t o work wirelessly unlike mos t other sewer inspection robots. A s a result of the wireless approach the robot has to carry an energy resource and mus t be able to act autonomo...

Basic sanitation services are essential for human development, promoting health and inhibiting the spread of waterborne diseases. The availability information on water at local level supports formulation, implementation improvement public policies aimed advancing provision basic to population. In Brazil, National Water Sanitation Data System (SNIS), administered by Ministry Regional Development...

In previous research efforts, we have shown that what seem to be sizable geographic differences in poverty rates in rural Peru can be almost fully explained by taking into account the spatial concentration of households with readily observable non-geographic characteristics-in particular, public and private assets. This does not mean that geography is not an important determinant of income ineq...

Under the city of Barcelona, which has a population of three millions of habitants in an area of 98 Km, there is a complex sewage system with almost 1500 Km of length. That system is characterized for being unitary, that is, its collectors carry rain water and residual water. The yearly rainfall is not very high (600 mm/year), but it includes heavy storms typical of the Mediterranean climate th...

We present an overview of a project that aimed to develop and implement computer vision techniques capable of extracting quantitative, three-dimensional descriptions of the shape of the surveyed pipe from sequences of images captured by an uncalibrated camera moving along a small-bore urban sewer. The resulting techniques are capable of use both on-line, during actual sewer surveys, and offline...

I n this paper a multijoint robot for sewer inspection tasks is presented. I n order to increase the operating scope the robot has been made able to run round or over obstacles, to follow sewage branches and is aimed to work wirelessly unlike most other sewer inspection robots. As a result of the wireless approach the robot has to carry an energy resource and must be able to act autonomously. I...
