“…These stations are at the downstream portion of the river, which carries significant quantities of organic/inorganic wastes. Previous records have also highlighted the effects of anthropogenic influences on the River Meenachil [39][40][41]. Only a few reports are focused on organic phosphorus in rivers/lakes, as it was previously believed that organic phosphorus contributes insignificantly to the phosphate levels in the water.…”

Phosphorus (P) concentration in rivers and lakes receives greater attention due to its significance in contributing to eutrophication. This study aimed at profiling phosphorus species in Vembanad lake (Ramsar site) and its adjoining rivers. Four phosphorus fractions (total reactive phosphorus (TRP), total acid hydrolysable phosphorus (TAHP), total organic phosphorus (TOP) and total phosphorus (TP)) were monitored according to premonsoon and postmonsoon seasons. Meenachil river mouth is a hotspot for eutrophication with high values of most of the phosphorus fractions. Among the four fractions TRP, TOP and TP were recorded maximum concentration during the premonsoon and postmonsoon seasons. Each fraction of TRP, TAHP, TOP, and TP had an average concentration of more than 300 µgL-1 P throughout two seasons, which is highly eutrophic. The result reveals that the surface water of Vembanad lake is highly polluted with phosphorus input and it may trigger algal growth and consequent destruction of the biodiversity rich wetland system.

“…Today there are many cities throughout world facing ansevere shortage of water and nearly 40 percent of the world's food supply is grown under irrigation and a wide variety of industrial processes depends on water. The environment, economic growth, and developments are all highly influenced by water-its regional and seasonal availability, and the quality of surface and groundwater 1 . The quality ofwater is affected by human activities and is declining due to the rise of urbanization, population growth, industrial production, climate change and other factors.…”

The seasonal variation study on groundwater water quality is very much important in identifying sequential changes in aquifer system for watershed management essential in sub basin level study. In this study, 9 nos of groundwater samples were collected in during post monsoon ( December,2017), and summer (April, 2018) seasons and analysed for pH, EC, TDS, TH, TA, HCO3, Ca, Mg, Na, K, Cl, SO4and F. The analyzed samples were compared WHO, BIS and ICMR standards. pH and EC values are within permissible limit for both the seasons. TDS values are higher the permissible limit in jangalpatti for post monsoon and summer season. Similarly, Na and Cl values are higher in Cumbum, jangalpatti, sankarapuram and uthamapalayam in both seasons and other parameters are within limit prescribed by BIS. From piper diagram, all the samples falls under Na-Cl and Mg-HCO3 types. In reference to irrigation suitability based on EC and Sodium AbsorptionRatio (SAR), %Na shows all the values comes under within Seasonal… R.Padmanaban et al.

The hydrological response of rivers to upstream reservoir regulation is one of the increasingly important research issues of watershed management. In this study, a hydrodynamic coupling model was used to simulate water level and flow processes of the Jing river and diversion flow of three outlets before and after the operation of TGP (Three Gorges Projects). The results indicated that water level and flow of three diversion channels both decreased in flood and dry seasons: the compensation regulation of the TGP was significant to maintain the water level and flow of three diversion outlets in the Jing river, but it also increased zero-flow days in the diversion channels of the Yangtze River. The riverbed erosion of channels in the upper reaches as well as lower reaches caused hydraulic gradient varying so much that it can’t be ignored in the water exchange process between the Yangtze and Jing river. This mechanism cooperates with the operation of TGP to change the natural process of the Yangtze-Jing river’s hydrologic process. This work provides essential information for future water resources and environmental management of the river-lake system and facilitates the effective flow regulation of dams, which has significant implications not only for the Dongting river-lake system but also the similar lakes and rivers elsewhere.
