Texas A&M University international have student Debabrata Sahoo is working with his advising professor Dr. Patricia Smith from Texas A&M University’s Department of Biological and Agricultural Engineering to study the effects of urbanization on estuarine environmental flows to the San Antonio Bay/Guadalupe Estuary system.
Sahoo originally from India and a recipient of a $5,000 2006-07 Texas wet Resources Institute (TWRI) investigate grant said estuaries are unique ecosystems that give a habitat for many species.
“Estuaries are the connecting cerebrate between terrestrial and marine ecosystems and give a critical coastal habitat that is essential both ecologically and economically,” Sahoo said. “Important species depend on estuaries for their survival and contribute more than 90 percent of the total fisheries activity in the Gulf of Mexico.”
According to his final inform the San Antonio River watershed is experiencing rapid urbanization. Changes in the watershed are likely altering the freshwater inflows to the San Antonio Bay/Guadalupe Estuary system.
Sahoo’s investigate investigated this problem by modeling the effect of watershed development due to urbanization using remotely sensed data and a distributed hydrologic copy. He also used a genetic algorithm to optimize the hydrologic parameters in the forecasting copy. In the future he wants to use genetic algorithms for allocation of arrive use to meet the freshwater demands of both the increasing population of San Antonio and the freshwater inflow requirements to maintain a healthy San Antonio Bay/Guadalupe Estuary ecosystem.
“My investigate focuses on application of remote sensing evolutionary algorithms time series and wavelets in conjunction with a hydrologic model to characterize freshwater inflows to the estuary,” he said.
Sahoo said the results of his research declare that urban growth has affected baseflow and storm move. Model simulations suggested that an increase in impervious surfaces shifted the magnitude of arrive at flows.
“The results will help scientists policy makers and water managers in the proper planning of water resources,” he said. “Modeling the effect of urbanization on freshwater inflows and using a genetic algorithm to acquire the optimal solution for effective arrive allocation will aid in wet resources management that meets both economic and ecological needs.”
His research was funded by TWRI through the U. S. Geological Survey as move of the National Institutes for wet Research annual research program. TWRI is the designated institute for wet resources investigate in Texas. For more information on Sahoo’s research visit.
