悬浮固体浓度和分布系数决定了污染物在湖泊水体中的命运。希尔顿（1985）提出了湖泊沉积物再分配的四种主要过程：随机再分配（RR）、间歇完全混合（ICM）、周边波作用（PWA）和斜坡滑动和滑塌。这些过程有可能使沉积物重新悬浮回水柱。再悬浮的程度，从而悬浮固体（SS）的浓度可以直接由主动redistribucion过程的影响。道格拉斯&里佩（2000）利用波混合层（WML）理论（SMITH & SINCLAIR 1972）研究了一个大型浅水湖泊中主要的沉积物再分布过程。他们发现，最大的30% WML值的平均值与内伊湖的沉积物再悬浮密切相关。本研究利用WML理论、时间序列沉积物捕获器和一系列湖泊，进一步检验WML理论的强度，并探讨以RR为主导再分布过程的湖泊悬浮物浓度预测模型。
The suspended solid concentration and the distribution coefficient determine the fate of a contaminant in the water column of a lake. HILTON (1985) idenrified four major sediment redistribution processes in lakes: random rediscribution (RR), inrermittent complete mixing (ICM), peripheral wave action (PWA) and sliding and slumping on slopes. These processes have the potential to resuspend sediment back into the water column. The degree of resuspension and hence the suspended solid (SS) concentration can be direcdy influenced by the active redistribucion processes. DouGLAS & RIPPEY (2000) used the wave mixed layer (WML) theory (SMITH & SINCLAIR 1972) to investigate the dominant sediment redistribution process in a large shallow lake. They found that the average of the largest 30% WML values correlated strongly with the sediment resuspension in Lough Neagh. The present scudy uses WML theory, a time series sediment trap, an d a range o f lakes to further test the strength of the WML theory and to investigate models for predicting the suspended solid concentration from the lake area in lakes where RR is the dominant redistribution process.
