The mean Chl a concentration for 555 nm, 560 nm and 640 nm were; 0.31 \u00b5g\/l, 0.33 \u00b5g\/l, and 0.51 \u00b5g\/l respectively. Chlorophyll a showed strong correlations at band 640 (r = 0.92). The bands centered at 670\/490 were the best in predicting CDOM and turbidity in the Shenandoah River Basin with an r2 = 0.56. Chemometrics analysis show that total phosphorous, nitrogen and turbidity can be predicted between 450 to 555nm and 670 to 710 nm, the range of wavelengths which indicated better predictability for spectroscopic analysis. The resultant concentration is used to develop predictive models to determine sensitive spectral variables for nitrogen, phosphorous, Chl-a, and CDOM.<\/p>","DOI":"10.4018\/ijagr.2016040102","type":"journal-article","created":{"date-parts":[[2016,2,19]],"date-time":"2016-02-19T07:39:41Z","timestamp":1455867581000},"page":"14-37","source":"Crossref","is-referenced-by-count":1,"title":["Water Quality Estimation Using Combined Water Chemistry and Field Spectroscopy in the Shenandoah River, Virginia"],"prefix":"10.4018","volume":"7","author":[{"given":"Mbongowo J.","family":"Mbuh","sequence":"first","affiliation":[{"name":"George Mason University, Fairfax, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul R.","family":"Houser","sequence":"additional","affiliation":[{"name":"George Mason University, Fairfax, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ako","family":"Heidari","sequence":"additional","affiliation":[{"name":"George Mason University, Fairfax, VA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"ijagr.2016040102-0","doi-asserted-by":"publisher","DOI":"10.1080\/014311698215676"},{"issue":"6","key":"ijagr.2016040102-1","first-page":"1378","article-title":"Satellite hyperspectral remote sensing for estimating estuarine and coastal water quality.
