In the Southeast U. In this part of Texas, we rarely get airmass thunderstorms for reasons that would take too long to explain here. One expected effect of climate change will be an increase in precipitation intensity: a larger proportion of rain will fall in a shorter amount of time than it has historically. Blue represents areas where climate models predict an increase in intensity by the end of the 21st century, brown represents a predicted decrease.
In parts of the Northern Hemisphere, an earlier arrival of spring-like conditions is leading to earlier peaks in snowmelt and resulting river flows. As a consequence, seasons with the highest water demand, typically summer and fall, are being impacted by a reduced availability of fresh water. Changes in water runoff into rivers and streams are another expected consequence of climate change by the late 21st Century.
This map shows predicted increases in runoff in blue, and decreases in brown and red. Find out why climate change matters. As societies change, so do scientific priorities. Water was once simply a commodity for human use and manipulation. Now, science and society have a greater awareness of how our actions impact nature. Add to collection. Nature of science As societies change, so do scientific priorities.
Activity ideas The Hub has a number of activities that model aspects of the water cycle. Building a water cycle models evaporation and precipitation. Water run-off models how rain can affect soil erosion and ground stability. Constructing an aquifer model explores the link between precipitation, surface and ground water.
Groundwater contamination models how contaminants enter aquifer systems. Water in Motion! Water moves continuously through our natural environment in a cycle. We pick up the water cycle with rain or melting snow, which in reaching land: Flows to rivers, creeks and lakes Seeps into the ground and wetlands where it is stored Plants absorb this water, and animals, including us, drink it.
Water Feeds Life Water supplies the needs of all life. Surface Water and Groundwater Surface water is the water that flows on the surface of the earth. Diving deeper… Groundwater Groundwater is stored in, and moves slowly through, aquifers. We use water for our day-to-day needs: Surface and groundwater are our drinking water sources We use water to irrigate our crops and golf courses Many industrial processes require water such as quarries In our urban areas, paved surfaces like roads, parking lots and buildings change how water moves over the landscape.
This leads to: Increased risk of flooding Higher rates of erosion on stream and riverbanks Increased water temperature in streams, rivers and lakes Impacts to fish and other animals living in water As rain and snowmelt falls on the ground, it becomes stormwater and can pick up pollutants such as: Pesticides, sediment and fertilizers from farm fields, lawns and gardens Water foul and pet waste Salt, oil and gas from parking lots, sidewalks and roads Take Action to Reduce our Impacts Green Your Property Join neighbours, farmers, business leaders and organizations across the watershed in creating positive environmental change.
Low Impact Development Slow down, soak up and filter stormwater to reduce the risks of flooding. Upcoming Events. More Events.
