Pollutants from various sources are entering groundwater systems due to changing land use and because groundwater environments are deteriorating at various scales worldwide. The health status of a groundwater environment can be used to indicate the degree of deterioration under natural or manmade stresses. This study proposes a concept for groundwater environment health and sets up an assessment index system to diagnose the health status of a groundwater environment based on a Bossel sustainable development index framework. The index system covers six basic categories (survival, effectiveness, freedom, security, adaptation and coexistence), which indicate various aspects of the health status of a groundwater environment. A projection pursuit (PP) model is developed for the assessment of groundwater environments and PP grade evaluation (PPGE) was used to evaluate the health status of a groundwater environment. The model was applied in Western Jilin province, China as a case study for groundwater environment management. Source

Hydrological data is usually large scale, including a lot of double counting. Hydrologists are facing new challenges with the massive hydrological data processing. Base on the data channel of MATLAB and Excel established by Excel Link, we studied a new method to process hydrological data in batches, namely, calling MATLAB functions in Excel directly by means of Data Management Function of Excel Link and implementing large-scale processing by the fill handle. It has overcome the shortcomings of the heavy workload caused by double counting, thereby improving the data processing efficiency significantly. Finally, by taking gray GM (1, 1) model in the application of runoff prediction for example, to illustrate the process of constructing new method by the combination of MATLAB and Excel. The results indicate that the new method presented in this article can give full play to tabulation function of Excel and data-processing capabilities of MATLAB, improving the efficiency and accuracy in the runoff prediction dramatically, which has important significance and practical value for massive hydrological data processing. © Sila Science.

Nowadays, agricultural non-point source pollution has become the main pollution source of water environment, especially for drinking water. Water sources protection has become a major problem in national economy and people's livelihood. Rural contiguous improvement project, including rural drinking water source protection, rural domestic sewage treatment, rural living garbage and livestock industry pollution treatment, can not only improve rural living environment, but also effectively reduce the non-point source pollution source of the water sources. A case study in north China showed that, after rural contiguous improvement, the amount of pollution source reduced significantly, so as to protect and improve the environmental quality of water source reserve effectively. © (2014) Trans Tech Publications, Switzerland.

In this paper, the Shitoukoumen reservoir of Yinma River basin has carried on the detailed investigation, use the over flow curve section of upstream and downstream the Shitoukoumen reservoir ecological base flow calculation, and sensitive water demand calculation. Considering the reservoir scheduling of economic benefits, ecological benefits and social benefits, and construct a complete set of reservoir scheduling optimization model, provides a theoretical basis for Shitoukoumen reservoir water dispatching. © (2014) Trans Tech Publications, Switzerland.

It has been very urgent situation that the Yitong River ecological environment gradually worsening and aquatic ecological environment restore, especially the city wastewater and wastewater emissions increased gradually, making the river self purification capacity decreased gradually. In order to maintain the basic ecological functions of rivers, it is very important to study the instream minimum and appropriate ecological flow. The Yitong River main control section's (Yitong Hydrology Station and Nongan Hydrologic Station) minimum and appropriate ecological flow is calculated based on Tennant method. After the Tennant method of flow standard is modified, the ecological water demand is 0.17×108m3, minimum in Yitong station, the suitable ecological water requirement is 0.23×108 m3, respectively, representing average annual flow in Yitong station 26.3% and 36.3 %. The minimum ecological water requirement of Nongan station is 0.77×108 m3, the suitable ecological water requirement is 1.13×108 m3, respectively, representing the Nong2 an station mean annual runoff 21.3% and 31.3%, providing a reference for ecological regulation of Yitong river ecological protection and restoration.
