Water Quality of Nour City Rivers
The goal of this research is recognition of species of pollution and a rough estimate of rate of transmitted pollution through northern Iran rivers to Caspian sea. Sampling from 3stations up-river, mid-river, and down-river in Lavij rood, Gland rood, and Sabze rood in a 6 month period from 2008/5/22 to 2008/11/22 coincides with warm, low rain, cold and rainy seasons and parameters as temperatur...
متن کاملWater quality management of heavily contaminated urban rivers using water quality analysis simulation program
Precisely management of water quality in urban rivers is of significant and water environmental capacity provide a useful tool. This study presented a water quality analysis simulation program model-based approach for dynamical load reduction in Ashi River, highly contaminated tributaries of Songhua River, China. The actual and surplus dynamic environmental capacity of CODCr and NH<s...
متن کاملWater Quality Monitoring in European and Turkish Rivers Using Diatoms
Water is one of the most essential factors for civilization, and also among the most important items in the new world order due to its unrenewable feature. In this regard, developed countries have continually been monitoring and classifying their water. For this reason, a number of EU countries have developed a national water quality system, considering characteristic structure of their own riv...
متن کاملEnergy Efficient Networks for Monitoring Water Quality in Subterranean Rivers
The fresh water in rivers beneath the Earth’s surface is as significant to humans as that on the surface. However, the water quality is difficult to monitor due to its unapproachable nature. In this work, we consider building networks to monitor water quality in subterranean rivers. The network node is designed to have limited functions of floating and staying in these rivers when necessary. We...
متن کاملHuman impact on the microbiological water quality of the rivers
Microbiological contamination is an important water-quality problem worldwide. Human impact on this category of contamination is significant and several human-related activities, and also the population explosion, have affected and are still affecting dramatically the aquatic environment. Extensive industrialization and agriculture have led to increased pollution and hydromorphological changes ...
