With the new year comes the start of legislative sessions in Maryland and Virginia, and its continuation in Pennsylvania. This is a critical time for bay restoration. At the halfway point between and the question is: Are we on track? See how Virginia waterfront property owner Norman Colpitts uses a cost-effective living shoreline to protect his property while benefiting the environment.
The living shoreline includes a small oyster reef to prevent erosion on his property. These oysters create wildlife habitat, filter and clean the water, and slow down waves before they erode the shore. This video captures the devastating effects of heavy rains that pummeled Pennsylvania the week of July 23, These scenes were shot on July 26, the day before the river crested.
The James River in Richmond overflowed its banks after heavy rain washed huge amounts of dirt and pollutants into the current. Clear, clean water turned the color of chocolate milk. Even days after the storm the surge continues as runoff flows miles downstream from the headwaters. Stay up to date about the Bay! Sign Up. And it offers steps that local, state, and federal governments can take to reduce pollution and achieve clean water for local streams, rivers, and the Chesapeake Bay.
Florida, Oct. When Hurricane Irene passed over Florida in , the heavy rainfall over land caused extensive amounts of runoff that first entered Florida's rivers which then dumped the runoff water, containing lots of sediment, into the Atlantic Ocean.
Florida, Dec. The east coast of Florida is mostly clear of sediment from runoff. The shallow coastal waters to the west of Florida are very turbid sediment-filled , perhaps from a storm that passed over a few days earlier. This story map discusses the problem with stormwater, the potential benefits and challenges of green infrastructure, and how this effort is evaluating its effectiveness. Skip to main content.

Science Center Objects Overview Maps When rain falls onto the landscape, it doesn't just sit there and wait to be evaporated by the sun or lapped up by the local wildlife—it begins to move due to gravity.
Below are map products associated with surface and overland runoff. Filter Total Items: 1. Urbanization increases surface runoff, by creating more impervious surfaces such as pavement and buildings do not allow percolation of the water down through the soil to the aquifer. It is instead forced directly into streams, where erosion and siltation can be major problems, even when flooding is not. Increased runoff reduces groundwater recharge, thus lowering the water table and making droughts worse, especially for farmers and others who depend on water wells.
Reference Terms. Runoff that occurs on surfaces before reaching a channel is also called overland flow. The air is full of water, as water vapor, even if you can't see it. Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head.
And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head. You can't see it, but a large portion of the world's freshwater lies underground. It may all start as precipitation, but through infiltration and seepage, water soaks into the ground in vast amounts.
Water in the ground keeps all plant life alive and serves peoples' needs, too. Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human A spring is a place where water moving underground finds an opening to the land surface and emerges, sometimes as just a trickle, maybe only after a rain, and sometimes in a continuous flow.
Spring water can also emerge from heated rock underground, giving rise to hot springs, which people have found to make a delightful way of soaking away their problems.
