项目摘要
Soil erosion is a serious problem in Australia and internationally. Each year 75 billion tones of soil are removed due to erosion causing siltation and reduced storage capacity of reservoirs (and in some cases dam failures), while reducing agriculture productivity. Also, the internal erosion of dams has historically resulted in about 1 in 200 dams failing. This project will develop a framework for understanding the initiation, progression and rate of erosion of soils including previously overlooked parameters. It will significantly advance the ability to manage and predict soil erosion. Engineers, land management authorities and dam owners will benefit directly through the development of new experimental and predictive tools.
土壤侵蚀在澳大利亚和国际上都是一个严重的问题。每年有750亿吨土壤因侵蚀而流失,造成淤塞和水库蓄水能力下降(在某些情况下还有水坝倒塌),同时降低了农业生产力。此外,在历史上,大坝的内部侵蚀导致大约200个大坝中有1个失败。该项目将制定一个框架,以了解土壤侵蚀的开始、发展和速度,包括以前被忽视的参数。它将大大提高管理和预测土壤侵蚀的能力。工程师、土地管理当局和大坝所有者将直接受益于新的实验和预测工具的开发。
