Sea Level Change: Basics
This lesson describes the physical processes, both natural and human-induced, that lead to changes in sea level. The processes described include climate induced changes in ocean heat content and volume, natural oceanic cycles, and both natural and human-induced changes in coastal land elevation. The learning is enhanced with rich graphics and periodic questions.
Primary Influences on Water Temperature for Inland Streams
This lesson explores the primary influences, or drivers, on water temperature of inland streams and rivers. We use a simulated flight, or flyover, where we look down at the features of the South Boise River in Idaho. An unregulated as well as a regulated reach of the river are explored (above and below the Anderson Ranch Reservoir), with a look at cross sections of the river and its environment at key locations during the flyover. We explore how environmental factors (climate, geography, stream morphology) impact water temperatures. Then, after defining the factors that affect water temperatur ...

A Glass Half Empty: regions at Risk Due to Groundwater Depletion
UNEP, 2012The tiny fraction of freshwater not bound up in ice sheets and glaciers comprises only a very small fraction of total global water volume (about 0.79 %) (1). Global use of that freshwater, however, has been growing at roughly twice the rate of global population for the past century (2,3) (Figure 1). Even so, this volume of unfrozen freshwater is still more than adequate to meet all human needs. However, this essential resource, which is mostly stored as groundwater, is distributed quite unevenly around the globe. Furthermore, physical and economic constraints make it impractical in most cases ...

Variations of Terrestrial Water Storage in the Yangtze River Basin under Climate Change Scenarios
Atmospheric and Oceanic Science Letters, Volume 3 Number 6. Ma Quian; Xie Zheng-Hui; Zhao Lin-Na - Science Press, 2010In this study, the water balance-based Precipitation-Evapotranspiration-Runoff (PER) method combined with the land surface model Variable Infiltration Capacity (VIC) was used to estimate the spatiotemporal variations of terrestrial water storage (TWS) for two periods, 1982–2005 (baseline) and 2071–2100, under future climate scenarios A2 and B2 in the Yangtze River basin. The results show that the estimated TWS during the baseline period and under the two future climate scenarios have similar seasonal amplitudes of 60–70 mm. The higher values of TWS appear in June during the baseline period and ...
Runoff Processes: International Edition
The Runoff Processes module offers a thorough introduction to the runoff processes critical for flood and water supply prediction. This module explains key terminology and concepts including the following: types of runoff, paths through which water becomes runoff, basin and soil properties that influence runoff, and numerical runoff modeling. Examples of popular runoff models are also discussed.
Watersheds: Connecting Weather to the Environment
This short course provides broadcast meteorologists with knowledge and instructional materials to help them understand watersheds as our environmental home and to help their viewers understand the relationship between the weather and the health and protection of the environment. Environmental impacts in many areas of the country result from the daily actions of people. We can easily see the consequences of a major oil spill at sea that is driven ashore by winds and ocean currents, but what about the fertilizer that people put on their lawns and the de-icer they apply to their driveway, or chan ...

IHP Series on Groundwater, VI-No.15. Groundwater for emergency situations
UNESCO, 2006This volume comprises the Proceedings of the International Workshop on Groundwater for Emergency Situations (GWES), held in Tehran from 29 to 31 October 2006, organized by the Regional Centre on Urban Water Management-Tehran (RCUWM) and by the UNESCO Tehran Cluster Office, with the support of UNESCO/IHP. The GWES International Workshop and the topics discussed therein have provided significant support to the methodology of investigation, management and risk mitigation of groundwater resources in the West Central Asia region often affected by droughts and floods. Thirty-four experts from 10 cou ...
Understanding the Hydrologic Cycle
This module helps students gain a basic understanding of the elements of the hydrologic cycle. Making use of illustrations, animations, and interactions, this module examines the basic concepts of the hydrologic cycle including water distribution, atmospheric water, surface water, groundwater, and snowpack/snowmelt.
