abstract = "Assuming that physico-chemical attributes affect the spectral
curve of sediments, the objective of this work is to study the
relationships of organic matter, phosphorus, nitrogen and
granulometry with the laboratory spectral reflectance (350 to 2500
nm) of Brazilian semiarid sediments from the bottom of reservoirs.
The study was carried out in the reservoirs Pereira de Miranda and
General Sampaio, belonging to the watershed of the Curu river, in
the state of Cear{\'a}. The results showed that sand and silt
produced positive and negative correlation with reflectance,
respectively. The best correlation for them was obtained in the
band positioned at 662 nm. The clay had negative correlation with
reflectance, especially at 2290 nm. The mostly correlated chemical
attribute with reflectance was organic matter with negative
coefficients from 567 to 761 nm, and a correlation peak at 662 nm.
For phosphorus, the correlations were positive and from 0.37 to
0.63 with a maximum value at 511 nm. On the other hand, nitrogen
behaved differently, with much lower correlation coefficients
(0.19 to -0.17). We concluded that the spectral reflectance of
sediments from the bottom of reservoirs can be used to estimate
their physical and chemical attributes, confirming that the
reflectance spectroscopy is a valuable tool for this purpose.",
