Scarcity of water is a major existing problem in India. Of all the available to us, only 3% pure and usable, with more than 7 billion people on earth. Rainwater most undervalued types freshwater available. harvesting one oldest simplest method for saving using water. It can be used residential household projects, even larger systems schools, hospitals other facilities. Considering scarcity our ...

in order to investigate the effects of super absorbent material on water saving and increasing rain water productivity under micro catchments water harvesting systems, a field experiment was conducted in east azarbaijan. the treatments included two mcwh patterns (small basins and semi-circular bunds), three catchments sizes, three runoff area treatments (natural, cleared and smoothed, wetting a...

Increased Cloud Condensation Nuclei (CCN) load due to anthropogenic activity might lead to non-precipitating clouds because the cloud drops become smaller (for a constant liquid water content) and, therefore, less efficient in rain formation (aerosol indirect effect). Adding giant CCN (GCCN) into such a cloud can initiate precipitation (namely, 5 drizzle) and, therefore, might counteract the ae...

We determined if winter drought stress could delay flowering and fruit development of immature ‘Valencia’ sweet oranges to avoid young fruit loss during late-season mechanical harvesting. Beginning in December over three consecutive seasons (2007–2009), Tyvek water-resistive barrier material was used as a rain shield groundcover under 13to 15-year-old trees. There were three treatments: 1) drou...

It is desired to simulate natural rain in a wind tunnel in order to investigate its influence on the aerodynamic characteristics of aircraft. Rain simulation nozzles have been developed and tested at JPL. Pulsed laser sheet illumination is used to photograph the droplets in the moving airstream. Digital image processing techniques are applied to these photographs for calculation of rain statist...

The paper reports very important findings on long term rain chemistry data from dry remote savanna site in Africa. The interesting part of observations is that the site has unique characteristics regarding chemical composition of rain water. In most of the temperate regions where acid rain is common phenomenon, the acidity is mainly reported due to very high non sea salt SO42-. The major role p...

In Papua New Guinea, a significant portion of morbidity and mortality is attributed to water-borne diseases. To reduce incidence of disease, communities and non-governmental organizations have installed rain catchments to provide drinking water of improved quality. However, little work has been done to determine whether these rain catchments provide drinking water of better quality than traditi...

and elevated ozone on tissue water relations of mature clones of a fast-growing genotype of ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and their half-sib seedlings. Whole seedlings and branches of mature trees were exposed to acid rain (pH 5.1 and 3.0) and ozone (ambient and twice-ambient) treatments in open-bottomed chambers. The acid rain treatment was applied to foliage weekly from Jan...
