In the summer of 1970-71, a change in the normal weather pattern occurred in Hobart, with a series of heavy thunderstorms of an intensity common in the tropics but not recorded before in Hobert. As a result of these storms, extensive local flooding occurred in suburban areas due to the overflowing of rivulets where they entered the flatter areas of the city. Subsequent investigations showed that in the piped sections of the revulets and their tributaries, there had been spare capacity and that most of the flooding was caused by the inability of gully pits on the steeply sloping ground to adequately transfer the water to the underground system. Full-scale field experiments were carried out to see if a more effective intake could be devised to deal with this problem. These experiments showed that the standard gully pit did not intake the quantities of water anticipated. A new type gully pit with deflectors and side intake has been designed and is now being field tested. /Author/
