Embung compote is a water structure that functions to distribute and ensure the availability of supply for crops or livestock in dry rainy season. Located Tempurejo Village, Wates District, Kediri Regency. micro-sized reservoir (reservoir) around agricultural land built accommodate amount rainwater during season become The current condition source experiencing problem decreasing resources part ...

Strong fieldwide gradients from southeast to northwest in gas/steam and 6"O have been found in steam produced from wells at The Geysers. These gradients result from recharge from the southeast that has increased liquid saturation in the southern part of the reservoir and flushed gases and high 6"O connate waters to the north and out of the system through surface vents. Variations in the steepne...

One of the main problems in operation hydrosystems for various purposes is silting up reservoir. Silting a reservoir leads to decrease useful capacity. And, course, hydrosystem's facility will not be able fully perform its functions. This issue particularly relevant territories located arid zone with transboundary rivers, whose water resources are used industries different types consumption (fi...

ABSTRACT Among several techniques for prevention and mitigation of reservoir sedimentation, bottom outlets arise as a means removing sediment deposited close to the dam. Given reduced removal provided by traditional under pressure flushing conditions, this article proposes new type structure that aims increase in direction parallel dam axis. An experimental installation was employed evaluate it...

Elimination of sediments from river reservoirs is a common management problem for hydroelectric power plants. Periodical flushing can have negative impacts downstream. This study investigated the impact of a flushing event on the physico-chemical changes in the downstream sections and on the consequences for the benthic macroinvertebrate community. A special emphasis was placed on trace metal f...

A detailed description is presented in this paper of small sand and water culture equipment. A number of large out-of-doors sand cultures both for tree and annual crops have also been constructed at the U. S. Regional Salinity Laboratory, Riverside, California. In their general features these latter cultures are like those described in an earlier publication (3). The more significant modificati...

Methylisoborneol (MIB) and geosmin are cyanobacterial metabolites that occur at nanograms per liter levels in surface water supplies and are responsible for many taste and odor complaints about the aesthetics of drinking water. This study evaluated three water supply reservoirs with bottom-release (hypolimnion) outlet structures in Arizona. MIB concentrations were always higher than geosmin con...
