水位变化条件下海湾水库盐分达标探讨
Salinity of water in an estuarine reservoir under water level decrease
摘要
Abstract
An estuarine reservoir in northern China is characterized by intermittent inflows, continuous outflow, and dynamic salt release from sediments. We developed a quantitative model coupling water quantity and salinity, and u-sing the proposed Muguandao reservoir as an example, examined factors that influence salinity, specifically those that cause it to exceed the standard. We also explore methods to maintain standard salinity levels in a mixed estuarine res-ervoir. The results showed that the cumulative effects of millimeter-scale evaporation on salinity in reservoir water are noticeable when the water level decreases. Under adverse hydrological conditions, salinity in a mixed estuarine reser-voir, affected by salt release from sediments, evaporation, and water outflow, tends to exceed the standard. In contrast with the constant water level conditions, salinity increased with increasing water outflow when water levels decreased. Therefore, decreasing daily outflow could help maintain salinity standards. To ensure water quality safety, the daily a-vailable water as determined from the integration of water quantity and salinity, should factor in the management of an estuarine reservoir.关键词
