Hydrologic Station

 

(1) An agency of the Hydrometeorological Service of the USSR that observes and studies the hydrologic conditions of bodies of water and territories. (Hydrologic stations on rivers study the water level and temperature, speed of the current, turbidity, and ice phenomena.) Hydrologic stations have observation points (posts) that are equipped with the appropriate devices and instruments. They are classified as river, lake, swamp, water-balance, avalanche, mudflow, glacial, and marine hydrologic stations.

(2) A location at some point at sea (or in a lake) with certain coordinates, where a series of hydrologic observations is made from a vessel, including observations of the condition of the sea (or lake) and the weather, the transparency and color of the water, its temperature and chemical composition at various depths, and the direction and speed of the current.

The study catchment is located in the upstream basin of the Huaibin hydrologic station in the Huai River basin, China (Figure 1).
Then, the model error for the validated SWAT model is estimated based on the in situ streamflow observations at the Huaibin hydrologic station. Besides, the observation error estimation for the ESA CCI SM is implemented before the bias correction on the basis of the model-simulated soil moisture.
Besides, there are six hydrologic stations (Dapoling, Changtaiguan, Zhuganfu, Xixian, Huangchuan, and Huaibin) (Figure 1) with daily streamflow measurements of 1992-2008 (the data quality issue exists for the years 2000 and 2001) in this basin.
The suitability of the tide gauge data is highly dependent of the location of the hydrologic station. The river regulations have large effects on the water level, leading to distorted seasonal signals.
Gauged water level time series are available from the Argentinean area of the basin, consisting 21 hydrologic stations of 7 rivers.
The XAJ model has been widely used in China for flood forecasting, hydrologic station network design, and water availability estimation [37].
The successive heavy rainfall storms lead to two peak discharges passing the main hydrologic station (Wangjia Dam) in the main channel of Huaihe River.
In this study, we focus on Yishu River catchment (upstream catchment of Linyi hydrologic station).
Runoff data of year and month in the Upper Minjiang River Basin between 1990 and 2005 was collected from Zipingpu hydrologic stations. According to the data analysis results, during the period 1990-2005 in Upper Minjiang River Basin, the annual runoff depth, and the annual precipitation both revealed a decreasing trend (Figure 3); annual average temperature was on the rise (Figure 4); minimum monthly average depth in dry season appeared nearly consistent in February; and February monthly runoff depth exhibited a decreasing trend (Figure 5).
More than 100,000 data values were collected in the H-L watershed from 1958 to 1985 at 74 hydrologic stations and 64 precipitation stations.
Water level and flow velocity were obtained daily at each of the 13 hydrologic stations, and water-discharge-rating curves were constructed.
