可以通过忽略侵入流体中的任何能量耗散来分析在水平地板上传播的平面重力流前部的运动。然而，最大侵入深度和前沿速度的相应结果与测量结果并不一致。发现差异部分是由于先前的研究人员目视确定侵入层的深度所致。还尝试将剩余的差异与侵入层和连续层中的放电联系起来。
The motion of the front of plane gravity currents spreading on a horizontal floor can be analyzed by neglecting any energy dissipation in the intruding fluid. The corresponding results for the maximum intrusion depth and the front velocity are, however, not in good agreement with measurements. The differences are found to be partly due to a visual determination of the depth of the intruding layer by previous investigators; an attempt is also made to relate the remaining differences to the discharge in the intruding and in the continuous layers.
