Introduction
The alteration of watercourses has been extensive in Sweden as well as in other industrialised countries. Since the end of the last century the water table of about 2500 lakes have been lowered in order to reclaim farmland. More than 600 of these have been completely drained. This particular activity came to a halt at the end of the 1950s whereas the ditching of wetlands and dredging and channelisation of watercourses for the benefit of forestry are still ongoing activities. The regulation of rivers for the purpose of meeting differential needs of hydroelectric power commenced in the beginning of this century, At that time, the floating of timber constituted the economically most important profit from exploitation of northern Swedish rivers. 相似文献

与其他工业化国家相似,瑞典的河流改道十分普遍。为了围湖造田,从19世纪末期至今大约有2500个湖泊的蓄水量减少,其中超过600个湖泊完全干涸。直到20世纪50年代末,专门的围湖造田行为才停下来,然而为了林业的发展,湿地筑渠、疏浚河道与对河道的渠道化改造却依然进行。为了满足水力发电的不同需要,本世纪初又开始了对河流的调控。那时瑞典北方河流的开发最重要的经济收希来自漂木运输。 相似文献

Applicability of Adapted Reservoir Operation for Water Stress Mitigation Under Dry Year Conditions 总被引:1,自引:2,他引:1

This paper introduces the conjunctive use of a deterministic water quality model and water balance criteria for supporting the assessment of simulation and to evaluate the effectiveness of proposed operation strategies. By this, the applicability of enhanced reservoir operation strategies addressing both water quality as well as water quantity aspects under water deficit conditions in dry years can be shown. Arguments will be developed to address stakeholders and decision makers in the context of a more conservative past operation regime. Results are presented for the Kaparas reservoir, which is located in the lower Amu Darya River, on the border of Turkmenistan and Uzbekistan. As being one out of four large reservoirs of the Tuyamuyun Hydro Complex (THC), the Kaparas reservoir could be increasingly used for drinking water supply for the lower Amu Darya region. The results for the dry year 2001 indicates that the combination of simulation together with practical assessment criteria confirm the applicability of adapted operation rules for THC reservoirs and ways can be found to supply the local population (of the lower Amu Darya region) with more potable water of higher quality even subject to a parallel reduction of water deficits. Future aggravation of water stress due to increasing population growth and water quality deterioration will require a more comprehensive consideration of water quality aspects in many arid and semi arid regions. The experience gained during this study emphasizes the fact that classical deterministic water quality models provide effective tools to address even more complex water quality problems under water stressed conditions, provided processing of results is performed, to support the decision making process. 相似文献

在水电、房建工程项目管理中,为了对成本和进度进行有效控制,必须同时监控成本和进度的变化。有效成本、进度综合控制的关键是只要一发现成本、进度差异和低效率就积极地着手解决它,而不是放任不管。特别是在水电工程里,进度控制尤为重要,问题越早提出,则对整个项目的冲击和经济效益的影响就越小。 相似文献
