The Prediction of Waste Water Dilution by a Long-Term Tracer Experiment
Prediction Waste Water Dilution Long-Term Tracer Experiment
2009/10/29
In general tracer experiments made for the evaluation of waste water dilution
in recipients have been of short-term type, with the tracer having an injection
time that is markedly less than the time...
Groundwater Recharge in Panjab State (India) Using Tritium Tracer
Groundwater Recharge Panjab State Tritium Tracer
2009/10/29
Vertical recharge to groundwater due to the 1972 monsoon plus supplemental
irrigation has been measured at 21 sites in the state of Panjab(1ndia) using tritigm
tracer. Average recharge is found to b...
