泰国的Klong Ngao河口是一条长7.5公里的潮汐溪，面向安达曼海，排出11.5平方公里的红树林沼泽。从丰水期到枯水期，河口的物理过程有很大的不同。在旱季，垂直均匀性占主导地位，沼泽表现得像一个蒸发池。盐和水被困上游，纵向梯度的结果，通过潮汐分散，营养物外流可能导致SiO2，可能NO2和NO3，但不是PO4。外流被困在沿海边界层。在雨季，短暂的当地洪水产生强烈的分层盐度和偶发性冲刷的河口，并可能使营养收支的测量不确定。在雨季，Klong Ngao红树林沼泽捕获了陆源沉积物。
The Klong Ngao estuary in Thailand is a 7·5-km long tidal creek facing the Andaman Sea and drains 11·5 km2of mangrove swamps. Physical processes in the estuary differ greatly from the wet season to the dry season. In the dry season, vertical homogeneity prevails and the swamp behaves like an evaporation pond. Salt and water are trapped upstream, longitudinal gradients result and, through tidal dispersion, nutrient outwelling may result for SiO2, possibly NO2and NO3, but not PO4. The outflow is trapped in a coastal boundary layer. In the wet season, short-lived local floods generate a strong stratification in salinity and episodical flushing of the estuary and may make measurements of nutrient budgets inconclusive. The Klong Ngao mangrove swamp traps land-derived sediments in the wet season.
