WAFLEX
WAFLEX is a spreadsheet-based model. It can be used to analyse upstream-downstream interactions, dam management options and water allocation and development options. Structure of the Model WAFLEX is set up as a network, where each cell is river reach, demand node or reservoir. Each cell contains a simple formula to add water flowing into it from adjacent cells, and to subtract any demand connected to that cell. The network is set up twice, in demand mode and in supply mode. The inputs to WAFLEX are: * river inflow time series - source area of where the model starts * demand node time series, e.g. a settlement water supply * reservoir rule curves and dimensions * time series from gauges for calibration The outputs of WAFLEX are: * time series for specified points on the rivers - these can be calibrated against gauges * time series of abstractions and shortages for each demand node * time series of reservoir levels Code can be readily added to generate the above outputs graph ...

Hydrological Transport Model
An hydrological transport model is a mathematical model used to simulate the flow of rivers, streams, groundwater movement or drainage front displacement, and calculate water quality parameters. These models generally came into use in the 1960s and 1970s when demand for numerical forecasting of water quality and drainage was driven by environmental legislation, and at a similar time widespread access to significant computer power became available. Much of the original model development took place in the United States and United Kingdom, but today these models are refined and used worldwide. There are dozens of different transport models that can be generally grouped by pollutants addressed, complexity of pollutant sources, whether the model is steady state or dynamic, and time period modeled. Another important designation is whether the model is distributed (i.e. capable of predicting multiple points within a river) or lumped. In a basic model, for example, only one pollutant mi ...

North China Plain
The North China Plain () is a large-scale downfaulted rift basin formed in the late Paleogene and Neogene and then modified by the deposits of the Yellow River. It is the largest alluvial plain of China. The plain is bordered to the north by the Yanshan Mountains, to the west by the Taihang Mountains, to the south by the Dabie Mountains, and to the east by the Yellow Sea and Bohai Sea. The Yellow River flows through the plain, before its waters empty into the Bohai Sea. The part of the North China Plain around the banks of the middle and lower Yellow River is commonly referred to as the Central Plain (). This portion of the North China Plain formed the cradle of Chinese civilization, and is the region from which the Han Chinese people emerged. ...

Heihe River
Ejin River (), also Etsin Gol, Ruo Shui () or Ruo He in ancient times, is a major river system of northern China. It flows approximately from its headwaters on the northern Gansu side of the Qilian Mountains north-northeast into the endorheic Ejin Basin in the Gobi Desert. The river forms one of the largest inland deltas or alluvial fans in the world. Its drainage basin covers about in parts of the Chinese provinces of Gansu and Inner Mongolia, which flows within the Zhangye area of Gansu; when it flows across Jiuquan area, it was renamed as Ruo Shui; when it flows across Alxa League, it is called Ejin River. History About 2,000 years ago, the river was said to have a much more abundant flow than it does today and thus its perennial reaches stretched much farther out into the desert than it does today. Parts of the river flow through the Hexi Corridor, a valley which once formed a significant portion of the Silk Road. The upper section of the river, also known as the Heihe (or ...

Spreadsheet
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term ''spreadsheet'' may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial ...
