Über dieses Buch

The book presents a comprehensive study of the percolation of water from surface runoff with a focus on the retention capacity and intensity of precipitation.

Discussing the state of the art in scientific knowledge and solutions for the infiltration of water from surface runoff, the book addresses a wide variety of rainwater management issues, from precipitation, surface runoff and water infiltration, to impact on the drainage system. Although modern urban hydrology has improved the management of rainwater runoff for flood protection, public health, and environmental protection, current methods of drainage in urban areas mean that there is a continued threat to the regime of water flow and water resources. In this context, the book presents a new approach to rainwater management based on a unique fusion of hydrology, hydrogeology, urban engineering, and water management. It also includes research findings that are helpful in developing recommendations and technical guidelines for the use of infiltration systems in urban areas.

Chapter 1. Rainwater Management in Urban Areas

Abstract

At present, a new trend is arising in regard to approaches which try to renew the developmental treatment of runoff and the quality of water, with growing interest and acknowledgement of the fact that renewing the natural water balance contributes to a healthier environment and improves living conditions in urban landscapes. In the past, rainwater was considered only as an inconvenience; today, it is considered with increased interest as a resource. Yet, despite progress many uncertainties exist in urban hydrology. Additional research is required into the time–spatial dynamic of urban precipitation, particularly in order to improve the short-term prediction of the amount of precipitation. All problems and challenges are covered by the uncertainty of climate changes, which adds the obligation to ensure that systems of rainwater management are adaptable and resistant to changes. Urban hydrology plays an important role in the resolution of these problems.

Chapter 2. Urban Hydrology

Abstract

Requirements for sustainable long-term environmental protection are rising at present. Not only for financial reasons, but mainly because of concerns about the permanent provision of water resources and the protection of ecosystems, there are doubts about the suitability of the current method of urban drainage. Essentially, such a method of urban drainage is required which ensures not only the protection of humans from the impact of nature but also the protection of the environment from human impacts. The essence of the future solution lies in finding an acceptable compromise between these objectives.

Chapter 3. Research on Rainwater Infiltration

Abstract

Rainwater management in urban areas takes into account the needs of both the environment and people. The urbanization process has a dramatic impact on water retention hydrology, leading to increased volumes and outflow rates, filtration losses and subsurface flow. The creation of paved surfaces results in drainage of rainwater into a drainage network, which contributes to the reduction of natural filtration. The essence of the solution to urban hydrology lies in finding an acceptable compromise as an alternative solution for the drainage of rainwater from a territory. The subject of the research described in this chapter is a solution to water infiltration from surface runoff and a comparison of the results obtained from field measurements, laboratory analyses and numerical calculations. Such research is necessary mainly due to insufficient information in the technical standards of the Slovak Republic in the field of infiltration systems and rainwater infiltration, as well as solutions to them.

Chapter 4. Investigation of Rainwater Infiltration in Model Areas

Abstract

This chapter presents research results in model areas I and II. The results include graphical processing of total rainfall and rainfall intensity in Košice, as the tabled rainfall intensities from Slovak Hydrometeorological Institute (SHMI) (Table 3.2) were available only for this area. More detailed results are given in the annexes: C (relationship between rainfall and infiltration), D (rainfall total) and E (rainfall intensity). The chapter also presents the filtration coefficients obtained from the hydrodynamic tests, from the grain curves and the calculations based on empirical relations. In the following, a developed model to calculate the emptying time of the infiltration device is verified.

Chapter 5. Evaluation of Achieved Results

Abstract

When constructing any building, it is necessary to take into account all aspects of the functionality and operational ability of the building. One important task is the drainage of rainwater from the roofs, car parks, roads or pavements belonging to the buildings. A very advantageous and simple solution has recently been to drain this water into the sewer system, but with the continual development of cities, the construction of new buildings, existing sewerage pipes and lines becomes under-dimensioned, and their constant adaptation to actual needs is impossible. The current state of sewerage systems is insufficient in this respect, and so in the case of torrential rains, if there is more rain in a few minutes than during the whole month, there will be local floods.

Chapter 6. Overview of Rainwater Management Facilities

Abstract

Implementation of European legislation into our system of technical standards introduces a new philosophy of water drainage and protection of watercourses. The aim of this new approach to town drainage is regulation, reducing rainfall flows, reducing the frequency of floods, reducing overall transposed pollution and minimizing its impact on the recipient, and preserving watercourses and groundwater resources in good condition to be able to fulfill their additional functions and to achieve sustainable urban development.

Chapter 7. Conclusion

Abstract

This chapter presents conclusions and benefits from the research of rainwater infiltration for the practical as well as scientifical purposes. The further research in the field of rainwater management in the urban areas is also outlined.
