Sediment from runoff on land can cover corals or simply turn the water cloudy, cutting them off from the sunlight they need to survive.

陆地流失物中的沉淀会覆盖在珊瑚表面，哪怕仅仅使海水变混，都会导致珊瑚就无法接受日光照射而死亡。

But those near the main Hawaiian island population centers are under pressure from sediment found in runoff, overfishing and invasive algae.

但是，生长在夏威夷主岛的人口聚集地附近的珊瑚礁却面临着径流沉积物、过度捕捞以及扩散性水藻等重重压力。

The seasonal variations in water and sediment discharges affect the distributions of annual runoff and sediment discharge.

水沙的季节性变化影响着年内的径流量、输沙量的分配情况。

The sediment of runoff was between 103 and 308 kg ha-1 h-1, while the soil losses by needle erosion were between 6, 3 and 61, 0 ton ha-1.

The soil erosion was measured through the needle erosion and the sediment in the runoff.

It was movement of particles of soil, but it has high roughness that reduces the transport capacity of sediment of the runoff.
