過水斷面The phase change of soil moisture and inflation of the frozen moisture c ause the reduction of hydraulic conductivity by reducing the area of flow section and the aperture of soil pore space, increasing the capillary resisting force to soil moisture, and decreasing the water potential gradient because of the increasing of movement distances of soil water
導水率減小是凍結土壤入滲能力減小的根本原因,而土壤中液態水的相變是導水率減小的根源所在。土壤水分的相變及其膨脹通過減小土壤水分過水斷面面積和孔隙孔徑,增大阻力和由於增長運動距離而減小水勢梯度使凍結土壤的導水率降低。Excavating riverbeds in one channel may not only reduce the velocity area in some areas but also increase the velocity in other areas by increasing flow rate in this channel without correspondent changes in riverbeds of rocky rapids. in result, the velocity in waterway may be increased instead of be reduced, the flow condition may also be deteriorated. thus, which branch should be excavated and how to excavate in improving the flow condition of the branch should be further explored
但在分汊河道內,情況較為復雜,在一汊河道內採取開挖措施后,雖然其過水斷面有所增加,局部流速相應降低,但是由於工程后,汊道的分流比將會相應變化,而石質河床一般無法通過沖淤變化以適應水流條件的改變,因此,航道內工程處的流速可能降低,也可能不降反而有所增加,惡化了航道的水流條件。So far as the aqueduct with large discharge and lower head is concerned, the non - uniform flow will occur in the aqueduct, when the discharge is enlarged after the water - carrying section being determined based on the design discharge and the given head ; for which the flow condition must be presumed, so as to determine the water surface profile
