Hydrologic Cycle

[Richter, B] 2003 Mar 11. Protecting Instream Flows: How Much Water Does a River Need? The Nature Conservancy. Listed on the US EPA Watershed Academy Web. <http://www.epa.gov/watertrain/river/>

This document is used as one of the required modules in the EPA’s Watershed Academy Certificate Program. It discusses the importance of streamflow restoration in sustaining biological diversity and natural ecosystem functions of rivers and riparian areas. It is especially applicable when establishing ideal water flows from dams and in projects aimed at restoring natural watershed functions and hydraulic regimes. This document was written in through the Nature Conservancy’s Freshwater Initiative.

[The Nature Conservancy] 2003. Indicators of Hydrologic Alternation and the Range of Variability Approach. Sustainable Waters Program. <http://www.freshwaters.org/tools/>

This website allows you to download the Indicators of Hydrologic Alteration (IHA) software package that is used by water resource managers. IHA uses daily hydrologic data (streamflow, river stages, ground water levels, etc.) to create a statistical description of daily stream flow and measure changes over time. IHA also includes the Range of Variability Approach (RVA) to assist adaptive management programs in identifying management targets.

[The Groundwater Foundation] 2004 Aug 16. Groundwater Glossary. Get Informed Webpage. <http://www.groundwater.org/gi/gwglossary.html>

Created in 1985 in Lincoln, NE, The Groundwater Foundation’s mission is to educate and motivate people to care for and about ground water. This webpage includes a comprehensive glossary of groundwater terms and concepts. This page also provides links to their home page where you can learn more about the organization and a “kid’s corner” with educational activities and material for students.

[Massachusetts Government] 2004 Sept. 7Q10 Fact sheet. Low Flow Inventory Webpage. <http://www.mass.gov/dfwele/river/rivlow_flow_inventory/7q10.html>

This website provides a thorough explanation of the term 7Q10 and other watershed management terms. It also provides links to informational pages on groundwater, physical environment, dams, and ecology as well as a glossary and an incredible resources page with further links to applicable water management topics: streamflow, habitat and ecology, water conservation, sources of data, groundwater recharge, stormwater infiltration, new technologies, etc. The website appears to have been produced in conjunction with Mass. Executive Office of Environmental Affairs, Mass. Department of Fish and Game, and Mass. DFG Riverways Programs.
