streamflows造句

• Streamflows are augmented by releases from Lake Mendocino and Lake Sonoma.
• Also of interest are the interactions between streamflows and sediment contribution.
• Nearby groundwater pumping has decreased stream discharge and streamflows and decreased dace habitat.
• The dam reduced streamflows on the lower of the Bull Run River, at.
• Lower summer streamflows and warmer temperatures could affect water quality by concentrating pollutant levels.
• Analysis of streamflows and habitat conditions includes:
• Other effects may include changes in agricultural yields, reduced summer streamflows, species disease vectors.
• Runoff from volcanic snowfields and glaciers maintains streamflows for drinking water, irrigation, fish and wildlife.
• The 1977 drought affected most the western United States and lead to decreased streamflows in the watershed.
• The growing tourism and recreation industries such as whitewater rafting also could be affected by lower summer streamflows.
• Also, water from the late winter rains are partially lost from streamflows because of evaporation from the reservoir surfaces.
• In the summer, without increases in rainfall of at least 15-20 %, higher temperatures and increased evaporation could lower streamflows and lake levels.
• Rivers and streams have benefited tremendously from June rains, according to the NWS . Streamflows are now running close to or above normal for this time of year.
• Its mission is to engage in and support voluntary, market-based efforts to restore and protect streamflows using permanent acquisitions of water, leases of water, and physical solutions.
• Seasonal precipitation produces streamflows that vary from up to ( 49, 000, 000 m 3 ) per day to as low as ( 110, 000 m 3 ) per day.
• Cyanobacteria are found in stagnant freshwater enriched with nitrogen and phosphorus from septic tank and agricultural fertilizer runoff, and may be flushed into the ocean when streamflows are high in the rainy season.
• Similarly, in northeastern Wyoming, which has large deposits of minerals, coal, and petroleum, competition between mining, energy, and other users could intensify for the meager summer streamflows.
• Lower streamflows and lake levels in the summer and fall could affect the dependability of surface water supplies, particularly since many of the streams in West Virginia have low flows in the summer.
• High sediment levels can kill fish directly, bury spawning beds, reduce light transmission, alter temperature gradients, fill in pools, spread streamflows over wider, shallower areas, and reduce production of aquatic organisms used as food by other species.
• A 42-inch-diameter, joint-use outlet pipe is provided to release water into the aqueduct system; an 84-inch-diameter flood outlet pipe and a 15-inch-diameter river outlet pipe are provided to release floodwater and small streamflows.
