*Flood Hazard*

Title Description
Surf Your Watershed from the U.S. Environmental Protection Agency Enter your zip code and it will give you the name of your watershed. Step by Step Guide
Surf Your Watershed offers:
  • how to locate your watershed
  • location maps of each of the more than 2000 watersheds in the United States
  • links to information about individual watersheds
    You may choose to connect to information by watershed, by location of the watershed, by theme, by keyword (examples---drinking water, birding, chemicals, coasts, nature center, national water quality inventory).
California Rivers Assessment Interactive Web Database Once you have your watershed name you can find a map for it here. Select "Search by Basin", and then select your watershed. Under "Maps Available" there is a section for "Static, Pre-defined Maps". There you will find a hydrologic basin map, and a shaded relief map of your watershed. The legends for each of the maps are listed separately and will also need to be printed out. Step by Step Guide (pdf)
"The California Rivers Assessment (CARA) is a computer-based data management system designed to give resource managers, policy-makers, landowners, scientists and interested citizens rapid access to essential information and tools with which to make sound decisions about the conservation and use of California's rivers."
Enviromapper for Watersheds There are a few issues with this resource. The interative map isn't very user friendly and the map doesn't have a scale. I recommend using the CARA website above to get a map of your watershed, but in case that site is down you could use this one. 
Science in Your Watershed: USGS "Science in Your Watershed; Locate Your Watershed" by the United States Geological Survey enables a map-based search of river drainage basins of the United States. The result of each search narrows the range of watersheds to subregions shown on larger scale maps with the hydrologic units noted. Once the hydrologic unit is known the user can navigate to information using "Links by Watershed."
Santa Ana Watershed Project Authority Map Server Create a map on the Interactive mapper of the Santa Ana River Watershed in Southern California, print the map or download layers for a GIS project. The Santa Ana Watershed Project Authority (SAWPA) provides maps and information including the Arundo trails, Cooperative Well Measuring Program, and watershed water quality.

List of Flood Prone Area Maps for California (pdf) The Map Collection carries "Flood Prone Area" maps for certain quadrangles in California. You will need to recall your topographic quadrangle name from your first assignment, and then check the list to see if there is a map available.
Flood Zone Designations and other Frequently Asked Questions (FEMA) This site will give you information on specific terms (ex: 100 yr. flood), as well as different flood hazard zone designations (ex: Zone X), and what they mean.
The National Map Viewer This is a good site to use if you are having trouble finding your location. One of its best features is that it offers updated street names. This site has been recently updated and I do not have a guide available. You can input your address in the search box or zoom into your location. You want to check the box labeled "Scaned Topo Maps". Make sure to use the print button in the top right corner of the window. It will create a pdf of your map. 5/17/12 MY

Quoted from the site: "The geology of an area has a profound effect on many things, from the likelihood of landslides, to the availability of groundwater in wells, from the amount of shaking suffered in an earthquake, to the presence of desirable minerals, from the way the landscape is shaped to the kinds of plants that grow best there."
USGS Information on El Niño Information on what El Niño is and it's effects on floods, landslides, coastal hazards, climate and other information.

Preliminary Soil-Slip Susceptibility Maps, Southwestern California "This group of maps shows relative susceptibility of hill slopes to the initiation sites of rainfall-triggered soil slip-debris flows in southwestern California. As such, the maps offer a partial answer to one part of the three parts necessary to predict the soil-slip/debris-flow process. A complete prediction of the process would include assessments of “where”, “when”, and “how big”. These maps empirically show part of the “where” of prediction (i.e., relative susceptibility to sites of initiation of the soil slips) but do not attempt to show the extent of run out of the resultant debris flows. Some information pertinent to “when” the process might begin is developed. “When” is determined mostly by dynamic factors such as rainfall rate and duration, for which local variations are not amenable to long-term prediction. “When” information is not provided on the maps but is described later in this narrative. The prediction of “how big” is addressed indirectly by restricting the maps to a single type of landslide process—soil slip-debris flows."
The maps included are for all or parts of the 1:100,000 quadrangles listed: Santa Barbara, Los Angeles, San Bernardino, Long Beach, Santa Ana, Oceanside, San Diego and El Cajon.

The North America Tapestry of Time and Terrain "The North America Tapestry of Time and Terrain (1:8,000,000 scale) is a product of the US Geological Survey in the I-map series (I-2781). This cartographic Tapestry is woven from a geologic map and a shaded relief image. This digital combination reveals the geologic history of North America through the interrelation of rock type, topography and time. Regional surface processes as well as continent-scale tectonic events are exposed in the three dimensions of space and the fourth dimension, geologic time. The large map shows the varying age of bedrock underlying North America, while four smaller maps show the distribution of four principal types of rock: sedimentary, volcanic, plutonic and metamorphic."

"In a new comprehensive study, scientists have determined that the chance of having one or more magnitude 6.7 or larger earthquakes in the California area over the next 30 years is greater than 99%." You can download the 4 page report. Here is a pdf of the map.
Seismic Hazards Map: Probable Earthquakes, 1994-2024 "This site presents hazard analysis in terms of average rates of earthquake shaking displayed on a map. This analysis predicts that somewhere in southern California (not everywhere-many residents would not be affected) should experience a magnitude 7.0 or greater earthquake about seven times each century. About half of these will be on the San Andreas "system" (the San Andreas, San Jacinto, Imperial, and Elsinore Faults) and half will be on other faults."
Global Seismic Hazard Map The Global Seismic Hazard Assessment Program (GSHAP) was launched in 1992 by the International Lithosphere Program (ILP) with the support of the International Council of Scientific Unions (ICSU). Here you will find online colorful seismic hazard maps of the World,-- The Americas -- Europe -- Africa -- Middle East -- Asia --and the South-West Pacific. Seismic hazard data and reports are also available.
Southern California, Earthquake Hazards Program, U.S. Geological Survey The Pasadena USGS Office offers extensive information on southern California earthquakes and seismicity. The website presents data on the most recent significant earthquake in southern California and information on past, and present earthquakes.
National Atlas of the United States The National Atlas of the United States of America presents "map-like views of America's natural and sociocultural landscapes." The Atlas offer maps, digital geospatial and geostatistical data sets, and capability for interactive selection and display of map layers.

Make interactive maps within your web browser! This program allows you to select and display map layers. Roam across America and zoom in to reveal more detail. Point at map features to learn more about them. Locate and map more than 2,000,000 geographic names in the United States.
Shaken Awake! Impacts of California Earthquakes on Buildings In 1996 The Association of Bay Area Governments (ABAG) compiled this study where existing residential buildings were broadly classified according to the three sets of categories described below:
  • the material of the structure of the building,
  • the height or number of stories of the building,
  • and the age of the building.
    These three categories enabled classification of the Bay Area's housing stock into thirteen building types.
    You can select one of the building types for data on habitability following past California earthquakes, or scroll down for more information on the classification system used.
