1.流域概述江桥水文站位于黑龙江省泰来县江桥镇,东经123°41′,北纬46°46′,流域面积177253km~2,基面为大连基面.白沙滩水位站位于吉林省镇来县丹岱乡,东经123°53′,北纬46°18′,1959年7月建站,基面1976年前为大连基面,1976年断迁移后为黄海基面.2 资料系列的选取2.1 江桥资料.江桥站枯水位选用1952年～1996年5～6月最低水位值.1961年10月,江桥水文站将基本水尺断面向下游迁移了1410m,并作了对比观测,因此1952年～1961年10月水位按下列改正:
1. Watershed Overview Jiangqiao Hydrological Station is located in Jiangqiao Town, Tailai County, Heilongjiang Province, east longitude 123 ° 41 ', latitude 46 ° 46', drainage area 177253km ~ 2, the base surface of the base surface of Dalian. White Beach Water Station in Jilin Province Dandai Township, Zhenlai County, east longitude 123 ° 53 ', latitude 46 ° 18', set up station in July 1959, the base surface before 1976 for the Dalian basal plane, the transfer of the 1976 Yellow Sea basal plane .2 data series selection 2.1 The data of Jiangqiao Station The lowest water level of Jiangqiao Station was chosen from the low water level from May 1952 to May 1996. In October 1961, Jiangqiao Hydrological Station shifted the section of the basic water downstream by 1410 meters and made a comparative observation, Therefore, in 1952 ~ October 1961 the water level was corrected as follows:
