In order to test the hypothesis that certain species can discriminate high and low dissolved phosphate concentrations, epilithic microalgae were collected and dissolved orthophosphate concentration concurrently determined at 63 rivers of Northern Mindanao. Microalgae were identified to the lowest taxon, and density of each species was estimated following standard methods for epilithic microalgae. Dissolved phosphate varied significantly between rivers with 27% of the sites registering high levels which were primarily attributed to anthropogenic input. Constrained multivariate linear Redundancy Analysis (RDA) showed that phosphate significantly explained the variability of abundance for Gomphonema sp.1, Melosira varians, Navicula concentrica, Navicula sp.8, Navicula sp.9, Navicula sp.12, Navicula sp.15, and Oscillatoria sp.1. Discriminant analysis showed that Gomphonema sp.1 and Navicula sp.12, and Oscillatoria sp.1 can discriminate high and low phosphate concentrations, respectively. Hence, these species may be regarded as practical environmental indicators of levels of dissolved phosphate in tropical river systems. This electronic document is a “live” template.

It is located in the Firouzabad watershed at the west part of Fars province. The first stage in the time series analysis was drawing the data diagram and finding the statistical parameters. In the second stage, stabilization of data was carried out by deleting the process and periodic components from the time series. Then, the auto correlation and the partial auto correlation functions of the data were drawn and the appropriate model was chosen from auto regressive (AR), moving average (MA) models and a combination of them, (ARIMA) or (ARMA). The result of this study, in addition to simulation and modeling the river flow, is data generation for the future condition that requires correct management and decision making. Using these data, one can predict the river's floodwater flow rate in the future.","PeriodicalId":262661,"journal":{"name":"2010 International Conference on Environmental Engineering and Applications","volume":"781 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117028209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
