Abstract In India, the implementation of river-cleaning operations through River Action Plans (RAPs) conventionally focuses on a reduction in concentrated or point sources of organic loading to the river, and is assessed by monitoring the consequent improvement in river water quality. However, in the case of Indian rivers or river stretches having substantial background pollution due to distributed or non-point loading of organic matter and nutrients, elimination of point sources of pollution may not substantially impact or improve river water quality. It is suggested that implementation of River Action Plans in India under such circumstances must be conducted using a multi-tier approach. The initial emphasis in such cases should be on the selection of priority stretches of the river, where pollution control will have maximum beneficial impact on the citizens, and interception and diversion of all concentrated or point loads of pollution from these stretches. In addition, measures to minimize non-point pollution and visible pollution to the river and initiation of riverfront restoration and development projects are necessary in these priority stretches. Such measures would result in aesthetic improvements, increase the beneficial uses of the river and its surroundings, and generate favorable public perception towards RAPs, though they may not be sufficient to enhance the river water quality to the desired levels. However, as a result of the above actions, public support for funding more expensive and longer-term river cleaning schemes, resulting in comprehensive reduction in organic and nutrient loading to the river from point and non-point sources all along its length, may be generated. The need for this alternative methodology for implementation and assessment of RAPs in India has been illustrated by taking the example of the Ganga Action Plan (GAP) and assessment of its implementation near the city of Kanpur in the state of Uttar Pradesh, India, as a test case.

Tigris River

Diyarbakır is the biggest city and the largest urban settlement in the Tigris Basin in Turkey. It has been gradually developing and growing thanks to the Southeastern Anatolia Project (GAP), and is one of the most important centers of industry, agriculture and animal husbandry in the Tigris Basin. The Tigris River is an important water source for the city, and it serves for irrigation, fishing, recreation and receiving wastewater. With the development of industry, agriculture and the growth of urban population, its pollution has become a serious problem. Pollution from domestic, industrial and agricultural activities has led to deterioration of water quality. In this context, the aim of the present study is to identify point sources of pollution and to assess the surface water quality of the Tigris River in the study area by monitoring physicochemical parameters. Diyarbakır produced a negative impact on the Tigris River water quality, particularly after the WWTP discharge. Concentrations of chemical oxygen demand, organic nitrogen, total nitrogen and total phosphorus increased markedly downstream of Diyarbakır WWTP discharge point. During the summer, the extent of organic pollution was so serious in the stations, downstream of WWTP, that dissolved oxygen became almost absent from the river water. The metal concentrations of all water samples were mostly below or close to the maximum permitted concentration for protection of aquatic life and drinking water.
