      Urbanization has a significant effect on many of the processes that control streamflow (McCuen, ). Hydrological effects of urbanization include: (a) a higher proportion of precipitation appears as surface runoff; (b) catchment response to precipitation is accelerated and the lag time between precipitation and runoff is decreased; (c) peak. The hydrological effects of the urbanization scenarios were assessed using Flow Duration Curves (FDC), mean discharge (Q-mean) and Flood Frequency Curves (FFC). FFCs were developed using Log Pearson Type III (LP III) distributions fitted to 35 years of the annual maximum series in order to investigate flood risks at the downstream end of the Cited by:

      THE GROUND'S HYDROLOGICAL RESPONSE Some of the most pronounced hydrological effects of urbanization are the changes in the runoff of precipitation water from the urban region. These changes are due to the fact that the natural drainage process, in which precipi-tation is converted to runoff, is completely changed in the urbanization process. ().

Aspects of Hydrological Effects of Urbanization. Urbanization both alters and complicates the natural hydrologic cycle. However, the effects are often not consistent, but depend on the nature and magnitude of the urban influence.

The effects of urbanization on four aspects of the hydrologic cycle are examined: (1) Low flow; (2) total runoff; (3)infiltration; and (4) ground Cited by: Hydrological impacts of urbanization are assessed on catchments.

• High, low and mean flows were impacted at a threshold of a 10% impervious area. • Waste water treatment facilities highly impact low flow but also mean flow. • Urban landscape patterns help interpret the divergent impacts of by: book.

Applications of hydrological models that focus on the effect of urbanization on hydrology in the United States have been documented for a variety of geographic regions, such as the Piedmont (Hejazi and Moglen ).

The current study relies on literature review and conceptual analysis to investigate the effects of urbanization and roof water harvesting on on-site and downstream hydrology of water-limited by: Considering run off as prime effect of urbanization to the hydrological cycle in terms of water infiltration, the intention of the study is to contribute to a better understanding of the relation of the local hydrological parameters in urban areas to the physical transformation of land covers as impervious built ups and develop an.

The effect of urbanization on the hydrosphere may also be defined in a broader sense. According to American geologists Savini and Kammerer; there are certain distinct phases of urbanization that might affect the hydrological cycle This phases can be.

Urbanization generally causes hydrologic change through increased imperviousness, increased connectivity (e.g., storm sewers), and increased delivery of pollutants.

Urbanization and Watershed Hydrology Urbanization Effects on Precipitation and Evapotranspiration For decades, it has been observed that urbanization commonly increases the storm runoff response to precipitation (Table 1) due to greater stormwater peaks generated by impervious surfaces.

Greater frequency and severity of flooding, channel erosion, and destruction of aquatic habitat commonly follow watershed urbanization. Alterations in the aquatic environment associated with these hydrological changes greatly compromise the normal.

Hydrologic Effects of Urbanization. Changes in the landscape as a result of urbanization may affect the natural hydrology by: Increasing the peak flow rates of runoff. Figures and illustrate a relatively natural hydrologic condition compared with that of an urbanized one.

As a consequence of these cumulative changes in. Roof water harvesting is a potential source of water for domestic and livelihood uses in water-scarce urban areas of the world such as sub-Saharan Africa (SSA). However, little is known about the hydrological impacts of incorporating roof water harvesting on on-site and downstream hydrology of urbanized catchments.

Therefore, the current review investigates the effects of urbanization Cited by: In this study, we carry out an assessment of the impact of urbanization on Butare, southern Rwanda and evaluate its effect on the hydrological process at the Migina catchment.

We used data from the meteorological stations of the Migina catchment, land-use maps of the region (obtained in and ) and GIS technology in order to analyse hydrological fluctuations Author: Olivier Clement Gatwaza, Xin Cao, Mukete Beckline.
