NRS-15482 | Burrinjuck Dam calculations - spillway models

This volume is consists of an original report dated 9 September, 1920, by the Committee of Engineers on the Burrinjuck Dam spillways. The members of the Committee were H.H. Dare, Commissioner, Water Conservation and Irrigation Committee, J.J.C. Bradfeild, Chief Engineer, Metropolitan Railway Construction, and E.M de Burgh, Chief Engineer, Water Supply and Sewerage. The report examines provision for floods in the original design of the dam, and after analysing historical information about floods in the vicinity suggests that the slipways may not be adequate. Revised plans were prepared by the Water Conservation and Irrigation Commission and experimental models were made to test recommendations. Attached to the report are experimental observations and calculations of the capacity of the spillways at Burrinjuck Dam, photographs of the experiments conducted on spillway models, and folded linen-backed plans of the models. The photographs are dated and there are explanations of the experiments they depict. Custody History This record series was handed to the Archives Authority of NSW on 11 June 1968 by the Bradfield family. It was apparently an archival estray.

本卷宗收录1920年9月9日由宾贾达克水坝（Burrinjuck Dam）溢洪道（spillways）专项工程师委员会出具的原始报告。该委员会成员包括：水利保护与灌溉委员会专员H.H.戴尔（H.H. Dare）、都市铁路建设总工程师J.J.C.布雷德菲尔德（J.J.C. Bradfeild），以及供水与排污部门总工程师E.M.德伯格（E.M. de Burgh）。
报告首先检视了该水坝原始设计中的防洪设施配置，经分析周边区域洪水历史资料后指出，原溢洪道或无法满足防洪需求。随后水利保护与灌溉委员会修订了设计方案，并制作实验模型以验证所提出的改进建议。
本报告附带的资料包括：宾贾达克水坝溢洪道泄洪能力的实验观测数据与计算结果、溢洪道模型实验的实拍照片，以及采用亚麻布背板装帧的折叠式模型图纸。所有照片均标注了拍摄日期，并配有对应实验场景的详细说明。
保管履历：本档案系列于1968年6月11日由布雷德菲尔德家族移交至新南威尔士州档案管理局，原属无主归档档案。
