Rainwater harvesting within the urban environment is being increasingly recognised for its important role in reducing pressures on mains water supply and reducing stormwater runoff. The extent to which rainwater tanks can improve our management of the urban water cycle depends on the level of usage of the rain-harvested water. By incorporating the hotwater service into the suite of uses of harv...

According to recent reports, millions of people across the globe are suffering from arsenic (As) toxicity. Arsenic is present in different oxidative states in the environment and enters in the food chain through soil and water. In the agricultural field, irrigation with arsenic contaminated water, that is, having a higher level of arsenic contamination on the top soil, which may affects the qua...

Prognostic equations for the rain mass mixing ratio and the rain drop number concentration are introduced into the large-scale cloud microphysics parameterization of the ECHAM5 general circulation model (ECHAM5-RAIN). For this a rain flux from one level to the next with the appropriate fall speed is introduced. This maintains rain water in 5 the atmosphere to be available for the next time step...

Nepal’s political institutions and administrative units were thoroughly restructured in 2015 with the promulgation of new Constitution. Several rural areas combined to meet definition urban threshold criteria classify into categories. Accordingly, over 3,900 local amalgamated 753 units, which, 293 are classified as urban. Within these newly defined areas, many natural environments have been con...

Water is a precious natural resource for sustaining life, agriculture and environment. The dependability on groundwater has reached high in all time recent decades due to reasons such as unreliable supplies from surface water vagaries of monsoon, increase demand domestic, agricultural other purposes. Karnataka largely dependent meet industrial, municipal, domestic irrigation needs. So, Rainwate...

The hydroxyl radical (OH radical) formation rates from the photo-Fenton reaction in river and rain water samples were determined by using deferoxamine mesylate (DFOM), which makes a stable and strong complex with Fe(III), resulting in a suppression of the photo-Fenton reaction. The difference between the OH radical formation rates with and without added DFOM denotes the rate from the photo-Fent...
