Thesis Submitted for the Degree of Ph. D. in the University of London THE HYDROLOGICAL EFFECTS OF URILANI SA'f ION IN ME CANON'S BROM: CATCI1LE T, IIAIZLO14IIEW TOI;N, ESSEX. GEORGEEDWARD HOLLIS Thesis submitted for the degree of Ph. D. in the University of London. 1974 2 ABSTRACT The effect of the construction of Harlow, Essex on the hydrology of the Canon's Brook is investigated using pre-recorded r infall and rundff records. Similar hydrological data covering a per od of urban- isation was found for 32 other English catchments. The 8.25 sq. mile clay basin of the Canon's Brook had an average rainfall of 23.9 inches per year during the study period 1950-68; a three year rural period was followed by urban expansion resulting in 16.6% of the catchment having impervious surfaces by 1968. Water yield was increased by urbanisation; a digital IýAAJaI simulation model of the rural catchment revealed increases in/water yield of between 0.3 and 4.9 inches with about 16% of the basin paved. The increase in yield was smallest in wet years and greatest in dry years, confirming the results of a synthesis of data from published papers. Low flows increased with modal flow rising from 2 to 4 or 5 cusecs during the study period. The mean maximum monthly floods increased 220% because of the urbanisation and the frequency of summer floods, particularly those in the range 40-100 cusecs, increased markedly whilst the frequency of winter floods did not alter. The mean unit hydrograph for the 16% paved basin had a peak 4.6 times greater than its rural counterpart and the time of rise and width of the unit hydrograph at 50% of peak flow were 44% and 20% of the rural values respectively. However, large floods of over 150 cusecs, with a return period of perhaps 20 years, were largely unaffected by urbanisation, thus confirming the results of a synthesis of published data which showed that the effect of urbanisation on floods is inversely related to the interval recurrence of the floods. The apparent enlargement of the channel because of the changed flood conditions was not statistically significant. Sediment accumulation in a regulating reservoir gave a rate of erosion of 0.088 inches for per century a period of construction activity which when compared figures with published supports the view that construction activity increases erosion and sediment yields.
