drainage catchment
解釋
排水流域-
At last, based on the feedback analysis of the data of site investigation, the suggestions about whether to supply drainage measures in the catchment of high - ductility soil area are provided
最後根據現場觀測資料進行了反饋分析，對在高塑性土區下游側是否有必要增加補充排水措施提出了論證意見。 -
The design capacity of the communal drainage system is intended for handling the surface runoff arising from rainstorms, the volume of which is much higher than the volume of wastewater being inappropriately discharged into the drainage system. even though some wastewater may find its way into the communal drains, the drainage system which is serving a large catchment area should be able to handle it without increasing the risk of flooding
公用排水系統的流量設計，是要把大雨所引致的地面徑流收集並排走，其容量及排流量遠遠超過錯誤排入的污水流量，加上集水區的面積廣闊，就算有污水錯誤排入，公用排水系統都足以應付，不會增加水浸的風險。 -
The main points includes : 1. study the basic flood design theories and methods of the middle or small catchment according to the characters of the middle or small catchment drainage of henan province
本課題主要包含以下一些研究內容： 1 、針對河南省中小流域的實際特點，研究中小流域設計洪水計算的基本理論與方法。 -
Then, by the comprehensive analysis of essential conditions for stone forest development, and the quantitative study on the evolution phases of bajiang karst catchment and the spacial coupling analysis of its hydro - geomorphological system, the paper studies the relationship between the evolution of bajiang karst drainage area and the development of stone forest, and, combined with the evolution history of the catchment, puts forward a model concerning the relationship between the evolution of bajiang karst catchment and stone forest development, in the mechanism of " tri - level erosion ", if a < s < c, the visible and actual height of stone pillars will keep on increasing, meanwhile, soil layer among stone pillars will become thicker and thicker, so the the height of stone pillars " root will become higher and higher, too
在「三重剝蝕」機制中，若a s c ，石柱的可見高度和實際高度會不斷增高，同時，石柱的根部的土層會增厚，其土下部分的高度也會不斷增大。若a c s ，說明石柱的實際高度在增加的同時，其可見高度也在增加，但土層會變得越來越薄，最終當底土被完全剝蝕掉后，氣下溶蝕和土下溶蝕的差異消失，此時a接近於c ，石柱的實際高度將停止拔高或極緩慢增長，並在各種物理、化學風化的作用下而變得日益矮小。若s a c ，石柱的可見高度將趨于變矮，但驅動石林發育的土層厚度將會增大。 -
As a kind of karst geomorphology, stone forest is always distributed in a kast drainage basin, its development is inevitably related to evolution of the whole catchment
作為一種喀斯特地貌形態，石林總是分佈於特定的流域中，它的形成和發育演化與其所在流域的整體演化必然存在著密切的聯系，石林的出現、消亡是和流域地貌的發育演化階段相關的。 -
On the basis of raster digital elevation model ( dem ) data over the laohahe river catchment in the upper and west area of the liaohe basin within inner mongolia autonomous region, the digital elevation drainage network model ( dednm ) is applied for assigning flow - vector directions over flat and depressional areas of the dem, for identifying stream network and watershed divides, and for establishing spatial topological structure of subcatchments and stream network
基於遼河水系老哈河流域柵格數字高程模型（ dem ）數據，採用數字流域水系模型（ dednm ） 、河流工具rivertools 、地理信息系統arcview軟體，根據地形提取水系信息，構建數字流域水系、子流域與河網的空間拓撲關系。
