We describe a technique for determining mean lake depth utilizing a systematically aligned dot grid. This technique is, on average, 55% faster than the traditional planimeter methods, depending on the type of planimeter and the size and complexity of the lake. No detectable bias is associated with results from this technique compared with those of traditional planimeter methods. The relationship ND = 4√A; where ND = the number of dots falling within the shoreline of the lake and A = the surface area of the lake in ft2, gives a quick estimation of the number of dots that should fall within the shoreline boundary of a lake for optimum sampling. 相似文献

A mathematical model has been developed to predict radiocaesium concentrations over time within individual compartments of the lake and its catchment. The lake has been divided into five compartments; catchment, lake water (epilimnion and hypolimnion during stratification), lake sediment and fish. Radiocaesium enters the lake via contaminated rainfall and catchment runoff. A proportion of this radiocaesium absorbs onto suspended solids in the lake. This proportion is represented by a distribution coefficient. Sedimentation of the suspended solids occurs at a rate defined by the areal removal coefficient and results in increased caesium concentrations in the sediment. The ingestion of radiocaesium by either water column or benthic feeding fish is described by transfer functions. The model has been tested against data collected from Esthwaite water and Windermere shortly after the Chernobyl reactor accident from May 1986 to December 1987. The model simulates observed radiocaesium concentrations in Esthwaite lake water and sediment and also in lake water, sediment and fish in Windermere. The model could form the basis of a valuable management tool for the water industry should a major airborne pollution event occur again. 相似文献

Delay in lake recovery caused by internal loading 总被引:1,自引:0,他引:1
A simplified model of the lake-sediment system is proposed, which aims to predict the long term evolution and the recovery time of eutrophied lakes.The model represents the state of lake and sediment each by means of a single variable. Having recourse to a well-defined set of assumptions as for sediment processes, and adopting time independent coefficients, the model balance equations can be solved analytically, and the evolution of the state variables towards steady state conditions, can be discussed in terms of characteristic times of the considered system. Particular attention is devoted to the consequences of P saturation of the solid phase in surface sediment layers, i.e. to a situation which is frequently present in eutrophied lakes.The model is applied to the case of the highly eutrophied Lake Varese (Northern Italy), in which internal P loadings from sediments appear to be substantial.Taking into account the coupling between lake and sediments, the time needed to attain the steady state P concentration compatible with the present P loadings is evaluated as 5 times the water renewal time of the lake.It is also shown to what extent the assumptions on sediment dynamics affect the model predictions. 相似文献
