Book Description
There is not an extensive literature on street sweeping. Much of the research that has been completed exists in the "gray" area of technical reports and government documents. Furthermore, a great deal of this research is locally based, and has not been widely published. Indeed, our review of the scientific literature, revealed that, while storm water quality has received a lot of attention, few academicians have been involved in street sweeping research per se. Thus, throughout our research into street we sweeper effectiveness, sweeping protocols, and sweeping practices, wished that there had been a book summarizing some of the important issues associated with street sweeping. As our frustration grew, we realized that we were uniquely poised to write such a book as our research had encompassed a variety of different projects including sweeper testing, waste management, and related storm water quality. Also, early on in this exercise, we recognized that there was a growing demand for information about street sweeping policies and management, especially for studies focusing on the effectiveness of different sweeping schedules, on waste management operations, and on non-point, pollution reduction practices associated with storm water runoff. It was abundantly clear that there was a profound lack of research on street sweeping that could assist with developing local, regional, or national policies. There was, in effect, little guidance for city managers on these issues.

Book Description
Previous field demonstration projects in metro-Atlanta have shown that seep berms, which are elongated sedimentation basins at the outlet of a disturbed land area, can provide high suspended sediment trap efficiencies with respect to coarse sediments on construction sites having drainage areas greater than five acres. Previous literature has shown that vegetative filter strips are efficient traps for fine suspended sediment in stormwater runoff. A combination of a seep berm and vegetative filter in series was studied in this thesis as an erosion control measure with quantification of its flow resistance and sediment removal efficiency. First, a field demonstration project was implemented to evaluate seep berms as a viable erosion control measure through a side-by-side comparison with the more commonly-used silt fences on construction sites with drainage areas less than five acres in metro Atlanta. High suspended sediment trap efficiencies were recorded for the seep berm on two separate sites, and the seep berm was shown to be superior to silt fences with respect to sediment control in the site runoff. Then a vegetative filter was studied in the laboratory in a specially-built flume for that purpose. The relationship between vegetative drag coefficient and various parameters reflecting flow conditions and vegetation density in steady, uniform open channel flow was studied in the flume. Both rigid, emergent vegetation and submerged, flexible vegetation were studied at two different plant densities. The application of porous media flow concepts to open channel flow through vegetation resulted in a collapse of data for vegetative drag coefficient for the various vegetation types and densities into a single relationship when plotted against vegetative stem Reynolds number. Point velocity and turbulence intensity profiles at different locations in the vegetative filter were recorded with an acoustic Doppler velocimeter to observe the turbulence structure of the flow and its effects on vegetative drag and settling of sediment. A sediment slurry consisting of a suspension of fine sand was fed into the flume, and an automated sampler was used to measure suspended sediment concentrations along the vegetative filter length for a series of discharges from which sediment flux and trap efficiency could be determined. Experimental data for trap efficiency were plotted against a dimensionless settling efficiency for each type of vegetation and density. These relationships, along with the one developed for the coefficient of drag, were applied in a numerical design technique that allows designers to determine the flow depth, velocity and trap efficiency of a vegetative filter of known dimensions for a given flow rate, sediment grain size distribution, slope, and vegetation density. In a typical design example, the combined trap efficiency proved that a seep berm followed by a vegetative filter can be a very effective erosion control measure.

Book Description
Approaches to Water Sensitive Urban Design: Potential, Design, Ecological Health, Economics, Policies and Community Perceptions covers all aspects on the implementation of sustainable storm water systems for urban and suburban areas whether they are labeled as WSUD, Low Impact Development (LID), Green Infrastructure (GI), Sustainable Urban Drainage Systems (SUDS) or the Sponge City Concept. These systems and approaches are becoming an integral part of developing water sensitive cities as they are considered very capable solutions in addressing issues relating to urbanization, climate change and heat island impacts in dealing with storm water issues. The book is based on research conducted in Australia and around the world, bringing in perspectives in an ecosystems approach, a water quality approach, and a sewer based approach to stormwater, all of which are uniquely covered in this single resource. Presents a holistic examination of the current knowledge on WSUD and storm water, including water quality, hydrology, social impacts, economic impacts, ecosystem health, and implementation guidelines Includes additional global approaches to WSUD, including SUDS, LID, GI and the Sponge City Concept Covers the different perspectives from Australia (ecosystem based), the USA (water quality based) and Europe (sewer based) Addresses storm water management during the civil construction stage when much of the ecological damage can be done

Book Description
Environmental and engineering aspects are both involved in the drainage of rainwater and wastewater from areas of human development. Urban Drainage deals comprehensively not only with the design of new systems, but also the analysis and upgrading of existing infrastructure, and the environmental issues involved. Each chapter contains a descriptive overview of the complex issues involved, the basic engineering principles, and analysis for each topic. Extensive examples are used to support and demonstrate the key issues explained in the text. Urban Drainage is an essential text for undergraduates and postgraduate students, lecturers and researchers in water engineering, environmental engineering, public health engineering and engineering hydrology. It is a useful reference for drainage design and operation engineers in the water industry and local authorities, and for consulting engineers. It will also be of interest to students, researchers and practitioners in environmental science, technology, policy and planning, geography and health studies.
