STORM SEWER DATA

FR0130

SEPT 1990

SUMMARY

I OBJECTIVES

  1. To provide a database for evaluation of sewer flow simulation models, in respect of: (a) extreme events; (b)accuracy of above ground flow routines.
  2. To add to the national database (held at the Institute of Hydrology) for possible future updates of sewerage hydraulic analysis models.

II REASONS

The limitations of existing sewerage hydraulic analysis models are apparent to many users. Many of these limitations arise from the paucity of relevant data for model development.

III RECOMMENDATIONS

  1. The gully meter catchment data, not included in the database, is analyzed and suitable events added to the database.
  2. The electromagnetic flowmeter calibrations are checked and the present data transfer arrangements are simplified.
  3. The Oxhey Lane and one other catchment used for data collection in the 1950's are re-commissioned to enable any long term changes in run-off characteristics to be identified.

IV RESUME

This report briefly describes the three catchments from which data are to be added to the database, Lammas Road (Coventry), Beaumont Leys (Leicester) and Chaddesden (Derby), the catchment instrumentation and the database held at the Institute of Hydrology.

Copies of the report are available from FWR, price 15.00, less 20% to FWR Members.
