In Ch 4 of Silent Spring‚ Carson brings about the fact that the most essential natural resource in the world‚ water‚ is being contaminated. With every spray and use of the pesticides and human-made chemicals‚ persistent as they are‚ the resulting effects spread throughout ecosystems. Bioaccumulation occurs through the levels of the food chain(biological magnification)‚ microorganisms and fish are exposed to the chemicals that render the water polluted‚ fish are eaten by birds and other aquatic life

Formula is one of the most frequently used urban hydrology methods in Malaysia. It gives satisfactory results for small catchments only • The formula is: C . y It . A Qy = 360 where‚ Qy = y year ARI peak flow (m3/s) C= dimensionless runoff coefficient yI t = y year ARI average rainfall intensity over time of concentration‚ tc ‚ (mm/hr) A= drainage area (ha) Or Q=CiA i = average rainfall intensity (in/hr)equals to tc A = catchment area ( acre) Q = Peak flow ( cusecs)
