摘要

[摘要]张建军，张建军。利用风挡指数评价露天蓄水池的风挡条件。湖泊保护区管理。XX: XXX-XXX。确定给定水体中受风影响的区域有助于实施一些蒸发控制方法，因为蒸发量是风挡的函数。本文以伊朗德兹大坝为例，提出了一种确定水库开放水域受风影响区域的方法。通过雪区最常用的风挡指数(Sx)，计算开阔水面上不同点的风挡。然后使用聚类分析方法根据风挡指数值对这些点进行分类。为此，计算了Sx值，然后使用湖面的28,321个点进行聚类。利用该方法，将水面划分为5个区域，其中5个区域具有不同的避风效果。平均而言，相当一部分湖面(66%)比其他部分更容易暴露在风中。因此，可以预测这些区域的蒸发量高于湖面其他区域。

Assessment of wind shelter conditions of an open water storage reservoir using wind shelter index

Abstract Sharifi MR, Shahi Z. 2020. Assessment of wind shelter conditions of an open water storage reservoir using wind shelter index. Lake Reserv Manage. XX:XXX–XXX. Identifying the wind-affected area in a given waterbody facilitates the implementation of some evaporation control methods because the amount of evaporation is a function of the wind shelter. In this study, a method is developed to identify the wind-affected area of open water in reservoirs, using the Dez Dam in Iran. Through the wind shelter index (Sx), which is most commonly used in snowy areas, the wind shelter was calculated at different points on the open water. The points were then categorized in terms of the wind shelter index values using cluster analysis. For this purpose, Sx values were calculated and then clustered using 28,321 points of the lake’s surface. Using this method, the water surface was classified into areas, with 5 parts having different wind sheltering. On average, a considerable part of the water surface of the lake (66%) was more exposed to the wind than other parts. Therefore, it can be predicted that the evaporation at these areas is higher than at other areas of the lake surface.

期刊介绍： Lake and Reservoir Management (LRM) publishes original, previously unpublished studies relevant to lake and reservoir management. Papers address the management of lakes and reservoirs, their watersheds and tributaries, along with the limnology and ecology needed for sound management of these systems. Case studies that advance the science of lake management or confirm important management concepts are appropriate as long as there is clearly described management significance. Papers on economic, social, regulatory and policy aspects of lake management are also welcome with appropriate supporting data and management implications. Literature syntheses and papers developing a conceptual foundation of lake and watershed ecology will be considered for publication, but there needs to be clear emphasis on management implications. Modeling papers will be considered where the model is properly verified but it is also highly preferable that management based on the model has been taken and results have been documented. Application of known models to yet another system without a clear advance in resultant management are unlikely to be accepted. Shorter notes that convey important early results of long-term studies or provide data relating to causative agents or management approaches that warrant further study are acceptable even if the story is not yet complete. All submissions are subject to peer review to assure relevance and reliability for management application.
