Other HyMet Projects
-
Climate Changes Tracking Project
is an informal study of temperature changes worldwide using data
provided by individual participants.
-
Simulating runoff of the Amargosa River
in California as
part of a hydrologic study of the groundwater connection to the
atomic waste repository at Yucca Mountain, Nevada.
-
Determining the connectivity between flowing springs and
groundwater aquifers at Montesol Ranch near Napa Valley,
California for the Perrier Water Company.
-
A hydrologic rainfall/runoff model to
simulate the flow of the North
Platte River, Nebraska for the State of Wyoming, Office of
the Attorney General.
The
North Platte River in Wyoming and Nebraska was the subject of a
lengthy interstate lawsuit in the 1930's and another lawsuit filed
in 1986. In dispute were the impacts of water development activities
on the flow of the river over the last 40-50 years with
Nebraska
making the charge that the reduced flow of the
North Platte
was due to excessive water-use in Wyoming. This report examined
changes in streamflow and consumptive use for the 120-mile reach of
the North Platte River between the Wyoming-Nebraska state-line and
the gage at Lewellen, Nebraska over the period from 1953 to 1995.
The study determined that the decreased flow of the North Platte was
caused by a significant increase in irrigation acreage and
groundwater pumping in Nebraska. Shortly after this report was
published on the HyMet website in 1999, the $250 million lawsuit was
settled out of court.
-
A mass-balance model for Columbia
Glacier, Alaska for use in conjunction with an iceberg
prediction model (see Iceberg Monitoring Project).
A paper, Using
low-altitude meteorological observations to calculate the mass
balance of Alaska’s Columbia Glacier and relate it to calving and
speed , describes this model and was presented at the
Tidewater Calving Glacier Workshop on February 28 - March 2, 1997,
at the Byrd Polar Research Center, Columbus, Ohio.
-
Reconstruction of the flow of Del Puerto
Creek, California
(near San Jose) to assess its potential for water supply.
-
The Iceberg Monitoring Project (IMP) was
started in 1996 by Austin Post and Wendell Tangborn under contract
to the Regional Citizen’s Advisory Council (RCAC) in Anchorage,
Alaska. The main purpose of this project is to reduce the hazard of
a possible oil tanker/iceberg collision. Columbia Glacier,
after hundreds or even thousands of years of relative stability,
began to break-up and retreat about 1980. There has been a 500
percent increase in the calving rate, which now reaches about 100
tons of ice per second during the summer months. The average calving
rate is about 7 million tons per day or about 2.5 cubic kilometers
per year. Its retreat rate is now approximately 0.7 km (nearly ½
mile) per year and will continue for another 20-25 years. The final
product of IMP will be an iceberg prediction model that uses tidal
observations and weather data to forecast the timing and the amount
of ice that will reach the shipping traffic lanes in Valdez Arm each
day. See the paper, Iceberg
prediction model to reduce navigation hazards: Columbia Glacier,
Alaska for further details.
