A new methodic for estimation the water quality parameters such as chlorophyll `a' concentration, absorption of `yellow substance' at 390 nm and Vsp--volume concentration of small particles from spectral vertical attenuation coefficient Kd((lambda) ), and spectral radiance was developed. These problems were solved by nonlinear programming methods with adaptive strategy. Adaptive strategy permits results with higher precision than the usual nonlinear methods and provides stability of solution in comparison to the least square roots method.
