摘要 本文利用数值模拟程序MARUN,对比了考虑和忽略密度效应两种情况的数值解,模拟了单一潜水含水层,分别取不同坡度时密度效应对水头波动的影响。模拟结果表明,在潮间带下部含水层中,坡度为10°时,考虑和忽略密度效应两种情况的数值解之间的最大误差为2.5%,该误差随坡度的增加而增大,坡度为46°时,误差达到百分之十几,说明密度效应在影响水头波动的同时会受到坡度的影响。 We simulated the density effect on tidal head fluctuations with the MARUN code. A single unconfined aquifer is simulated. It has different beach slopes. Numerical simulation results indicated that, when the beach slope is 10 ° , the maximum error is 2.5%, which appears on the sea-land interface. The maximum error increases with the beach slope. When the beach slope is 46°, the maximum error becomes more than 10%. It shows that the water table fluctuation of the single unconfined aquifer is affected by both the density effect and the beach slope.
