The generalized stream X-machines (stream X-machines with basic functions replaced by relations and having as output, strings of symbols rather than single symbols) with output delimiter (any output string has at the right end side a special delimiter) are introduced. It is proved that testing methods similar to those already developed for ordinary determi-nistic stream X-machines may be applie...

Accurate and detailed information of hydrological balance, and its dynamic nature is needed to develop strategies for sustainable use and management of water resources. In this concern, a fully integrated MIKE SHE model was developed to study the hydrological balance of the Chirchik River Basin, Uzbekistan. Parameters in the model were calibrated and simulated results were validated for the per...

The delta of the River Senegal was modified substantially by the construction of the Diama dam in 1986 and the floodplain and estuarine areas on the Mauritanian bank were affected severely by the absence of floods. In 1994, managed flood releases were initiated in the Bell basin (4000 ha) of the Diawling National Park, as part of a rehabilitation effort. The basin was designated as a joint mana...

The sedimentation basin is an important part of hydraulic engineering. Because the prototype size too large and not easy to analyze, Mike 21 has advantages input, conversion, analysis, demonstration data results, which are flexible convenient; however, this method been used in engineering by previous researchers. This research Yellow River Diversion Project as object, a simulation model channel...

An approach of models approximation, applicable in the model-based optimization of water resources, is described. It was applied to the optimization of a system of the three reservoirs located in the Apure river basin in Venezuela. Its development plan requires to increase the period when the river is navigable along the certain reach. The problem was posed as a multi-criterial decision making ...

This paper applied the fuzzy comprehensive evaluation (FCE) technique and analytic hierarchy process (AHP) procedure to evaluate the wastewater treatment for enterprises. Based on the characteristics of wastewater treatment for enterprises in Taihu basin, an evaluating index system was established for enterprise and analysis hierarchy process method was applied to determine index weight. Then t...

background: zayandeh-rood river is the only perennial river in the central basin of iran that has fresh water. water from this source is used for drinking, industrial and agricultural purposes. drinking water is extracted from upstream portion (upstream of chamaseman dam) of zayandeh-rood river and therefore its quality is very important. due to growth of population, industry and other factors,...
