Progress Report On Effects Of Contour Banking On Surface Runoff At The Berkshire Valley Experimental Catchment (Near Moora) 1961-82, K J. Bligh
Resource management technical reports
The time lag prior to peak runoff following rains of comparable high intensity increased by approximately 80 per cent in the largest event after the construction of contour banks. Although 80 per cent more runoff also occurred because the catchment was wetter and had been cultivated for three years in a row, the peak rate of runoff increased by only approximately 20 per cent. That the peak rate was not increased by 80 per cent, may be primarily attirbuted to the effect of the contour banks.
Preliminary Groundwater Investigations In Relation To Soil Salinity At Fitzgerald, Western Australia, C J. Henschke
Preliminary Groundwater Investigations In Relation To Soil Salinity At Fitzgerald, Western Australia, C J. Henschke
Resource management technical reports
This study investigated soil salinity problems in relation to new land releases at Fitzgerald near the south coast of Western Australia. Fairly widely spaced set of bores was established to compare the groundwater hydrology regimes beneath cleared and virgin land. A large storage of soluble salts (over 100 kgm-2 in some profiles) was measured in the pallid zone clays under both cleared and virgin land conditions. Seasonal fresh to brackish perched watertables were found to overlie highly saline deep waterbles at a number of valley sites on land which has been cleared for agriculture during the past 15 years. Salinity …
