Cassie Stuurman is a geophysicist at the University of Texas.In 2016,she found evidence of a huge ice deposit(沉积)on Mars.“If these researchers are right,this is the first time we’ve found evidence of a large water body on Mars.”Stuurman said.Researchers are not yet sure how deep ...
The decrease resulted from an increased use of surface water that became available from Lake Livingston on the Trinity River during late 1976. During 1975-79, withdrawals of ground water decreased in the Pasadena, Katy, Baytown-La Porte, Johnson Space Center, Texas City, and Alta Loma areas ...
groundwater and GDE training data (n = 34,454 training points; Extended Data Fig.1and Extended Data Table1) to map the likely presence of both aquatic and terrestrial GDEs at roughly 30 m resolution across global drylands. Within our random forest model, training data are used within...
using data collected between 1976 and 2019 (TableS1). We analyzed water clarity indicators over time in seven reservoirs invaded by zebra mussels (Blue Springs, Bull Shoals, Jacomo, Lake of the Ozarks, Lotawana, Smithville, Truman) to assess whether there was an abrupt shift in water clarity ...

摘要:The computer program AQUASIM was used to model biofilter experiments seeded with Lake Austin, Texas mixed-culture nitrifiers. These biofilters degraded four trihalomethanes (THMs) (trichloromethane (TCM) or chloroform, bromodichloromethane (BDCM), dibromo-chloromethane (DBCM), tribromomethane (TBM...

In Graham County between 90 and 100% of water is used for agriculture (U.S. Geological Survey, 2022a Table 1), and based on land use data, most of the water use likely occurs in the Safford Valley between these two sites. Globally, including the UCRB, irrigation return flows have ...
Lake Travis – the water levels were VERY low One of our favorite moments was the tailgate party in the parking lot! A little Justin celebration COTA magic Buttercup enjoyed every moment! Hi Morgan. We will be home soon! In Texas everything was fabulous!
