Rivers can absorb certain amounts of contamination relying on different factors such as: river discharge, the primary conditions of the river, the river depth, discharge and the river viscosity of the offloaded wastes in the river. From parameters of water quality point of view, it is recom-mended to determine some parts of the river which are lower than the standard level in order to find out ...

Clostridium perfringens (CP) and sulphite reducing clostridia (SRC) densities in the Selangor River, Bernam River and Tengi River Canal were examined between April 2007 and January 2008. Water samples were taken from two or three locations along each river, using either depth-integration or grab sampling methods. The downstream sampling site of the Selangor River, Rantau Panjang, reported the h...

So far many optimization models based on Nash Bargaining Theory associated with reservoir operation have been developed. Most of them have aimed to provide practical and efficient solutions for water allocation in order to alleviate conflicts among water users. These models can be discussed from two viewpoints: (i) having a discrete nature; and (ii) working on an annual basis. Although discrete...

The paper presents the state-of-the-art in flood forecasting and simulation applied to a river flood analysis and risk prediction. Different water flow forecasting and river simulation models are analysed. An advanced river flood forecasting and modelling approach developed within the ongoing project INFROM is described. It provides an integrated procedure for river flow forecasting and simulat...

introduction the khoshk river is originated from golestan and ghalat highlands and flow in a northwest and southeast direction. after traversing a short distance it covers golestan and dukohak from the right and the ghasr ghomshe tributary from the left. then, in a direct cross from the middle of shiraz metro police, it will divide it into half in south and east and at the end it will pour into...

We compared the values of the biomass, chemical composition and nutritive value of the emergent aquatic macrophyte S. alterniflora in a river affected by the discharge of domestic sewage (Guaú River) and in an unpolluted river (Itanhaém River). S. alterniflora, water and sediment samples were obtained in the two rivers in November, 2001. The Guaú River presented the highest levels of Total-N an...

The Illinois River is one of the major tributaries of the Mississippi River in the central United States with a drainage area of 75,156 square kilometers. The Illinois River connects the Great Lakes with the Mississippi River through the Illinois Waterway that consists of eight lock and dams along the Illinois River and its tributaries. Because of its central location in the state and being the...

Today, there are varieties of methods for determining the risk flooding in different areas a catchment. However, use GIS-based weighting is receiving increasing attention among researchers. In early 2019, severe and continuous floods occurred some provinces Iran. Khorramabad was one cities most affected by floods. Regrettably, during construction development city, minimum distance from roads vi...
