Present status of urban hydrology - A research report by National Institute of Hydrology

The study reviews the present status of urbanization in the developed and developing countries and assesses the changes in urban hydrological cycle owing to this. The softwares used for studying urbanization and sanitation issues in the urban areas have been reviewed.

The constant increase in impervious area due to increasing urbanization is resulting in an increased runoff in less time leading to an enhancement of the runoff rate. The hydrological problems associated with these are also increasing. Several hydrological models have been developed to provide better estimation of runoff from urban catchments.

An extensive review of literature on urban hydrological modeling and catchment research has been done in the report. This shows that in almost all the countries, authentic data on long term basis is not available, specially the discharge data through urban drains.

The technology transfer or information exchange programs, data on pollutant transport, snowmelt database and validation of runoff models for water quality measurements are some of the aspects that need to be studied.
