至少有260万个小型人工水体点缀在美国本土的景观中;大多数位于该国的东半部。这些特征约占美国静水面积的20%，它们对水文学、沉积学、地球化学和生态学的影响显然与其面积成比例。这些特征局部地提高蒸发，转移和延迟下游水流，并改变地下水的相互作用。显然，它们拦截的侵蚀土壤与更大、更好记录的水库一样多。估计垂直加积率要高得多，因此，推断沉积化学反应必须是不同的小功能比大的。最后，这些特征大大改变了整个景观的水生栖息地的特征。(C)2002 Elsevier Science B. V.保留所有权利。
At least 2.6 million small, artificial water bodies dot the landscape of the conterminous United States; most are in the eastern half of the country. These features account for approximately 20% of the standing water area across the United States, and their impact on hydrology, sedimentology, geochemistry, and ecology is apparently large in proportion to their area. These features locally elevate evaporation, divert and delay downstream water flow, and modify groundwater interactions. They apparently intercept about as much eroded soil as larger, better-documented reservoirs. Estimated vertical accretion rates are much higher, hence, inferred sedimentary chemical reactions must be different in the small features than in larger ones. Finally, these features substantially alter the characteristics of aquatic habitats across the landscape. (C) 2002 Elsevier Science B.V. All rights reserved.
