河流比降比率 channel gradient ratio ; [水文] stream gradient ratio
弯曲型河流的水流运动研究包括流速及流速分布、比降、流场分布、环流运动、紊动特性等。
The research about the bend-flow includes velocity, the distribution of velocity, slope, the distribution of flow, circumfluence of flow and the characteristic of turbulent.
并且由于海平面高度相对稳定在较高位置，河流纵比降较小，流速也较小。
The sea level stops in a high position for a long time, so both drop of water and current velocity are small.
