Examples
- Beven 18 suggested that when it is applied in its original form to a river basin with thin soils over an imperme - able base , the quasi - steady state approximation holds . however , he also noted that for a variety of alternative transmissivity profiles , or when the saturated depth of the aquifer is large , the deviation in the actual shape of the water table from a steady - state shape can be both large enough and last long enough to call into question the assumption of quasi - steady dynamics
Beven 18也也指出这种“拟稳定”的地下径流机制虽然能够较好地应用于那些不透水层之上的土壤厚度比较薄的流域,但对于那些非饱和土壤层的厚度随空间的变化较大也就是地下水位的变化比较大,或者潜水面的厚度较大的流域,使用这种“拟线性”的topmodel地下径流机制就容易产生问题
