Seasonal prediction of winter extreme precipitation over Canada by support vector regression
winter extreme precipitation Canada support vector regression
2011/1/7
For forecasting the maximum 5-day accumulated precipitation over the winter season at lead times of 3, 6, 9 and 12 months over Canada from 1950 to 2007, two nonlinear and two linear regression models ...
Application of genetic algorithms for optimal seasonal furrow irrigation
Application genetic algorithms optimal seasonal furrow irrigation
2009/12/4
A quasi-optimum irrigation season calendar based on economic profit maximization for sloping and runoff-free furrows can be obtained by OPTIMEC (EConomic OPTIMization, in Spanish), a seasonal furrow i...
VARIABILITY OF SEASONAL AND ANNUAL RUNOFF IN NORWAY
VARIABILITY SEASONAL AND ANNUAL RUNOFF NORWAY
2009/10/29
A preliminary map of variability of annual runoff in Norway has been
prepared based on estimates of the coefficient of variation cv for 56
non-regulated discharge stations having more than 35 years ...
The paper presents a method for testing second order stationarity against
the alternative that seasonal variations take place in the autocovariance
function. This is a modification of a test suggest...
Seasonal Variability in the Pole-to-Pole Water Vapor Balance During the IGY
Seasonal Variability Pole-to-Pole Water Vapor Balance IGY
2009/10/29
A study of the vertically integrated fields of water vapor and its transport on a
planetary scale derived from aerological data taken during the IGY (International
Geophysical Year) is presented. Th...
Seasonal Fluctuations of Physical and Chemical Parameters of a Weir Basin in a Regulated West Norwegian River
Seasonal Fluctuations Physical Chemical Parameters Weir Basin
2009/10/28
Both before (1967-69) and after (1976-78) the regulation of the river Ekso in
western Norway, physical and chemical analyses were made of the river water.
After the regulation water samples for chem...
The Effect on Storm Runoff Response of Seasonal Variations in Contributing Zones in Small Watersheds
Storm Runoff Response Seasonal Variations Contributing Zones
2009/10/28
Storm runoff production by saturation overland flow has been studied in two
small watersheds in south-central Ontario. One is in rural land use and contains
a wetland. The total saturated zone is at...
Utilization of Satellite Snow-Cover Observations for Seasonal Streamflow Estimates in the Western Himalayas
Satellite Snow-Cover Observations Seasonal Streamflow Estimates Western Himalayas
2009/10/28
The results presented in this study indicate the possibility of seasonal runoff
prediction when satellite-derived basin snow-cover data are related to point
source river discharge data for a number ...
Seasonal Variations of Oxygen-18 in Soil Moisture and Estimation of Recharge in Esker and Moraine Formations
Seasonal Variations Oxygen-18 Soil Moisture Moraine Formations
2009/10/28
The use of Oxygen-18 as a natural tracer of soil moisture and estimation of
recharge in different types of soils is presented and discussed. The 8 values ~f
180 in summer and winter precipitation in...
Soil Moisture Deficits in South-Central Sweden I-Seasonal and Regional Distributions
Soil Moisture Deficits South-Central Sweden Seasonal and Regional Distributions
2009/10/27
Some commonly used assumptions about climatically induced soil moisture
fluxes within years and between different parts of a region were challenged
with the help of a conceptual soil moisture model....

Nonlinear Covariance Seasonal Snowmelt Snow Cover Western Himalayas
2009/10/26
Log-linear, exponential and fractional relations for estimating seasonal snowmelt
from early-spring snow accumulation in the Indus and Kabul river basins
in the western Himalayas are developed with ...
Seasonal Variations in Suspended Sediment Yield in the Baltic Sea Drainage Basin
Seasonal Variations Suspended Sediment Yield Drainage Basin
2009/10/26
The aim of this article is to describe the seasonal fluctuations of suspended
sediment yield in the Baltic Sea drainage basin and to quantify the monthly
inflow of suspended sediment to the Baltic. ...
Areal Extent of Seasonal Snow Cover in a Changed Climate
Areal Extent Seasonal Snow Cover Changed Climate
2009/10/26
In mountain snow basins, a change in climate will likely cause a change in the basin snow cover extent. A procedure for evaluating whether a given climate change scenario will speed up or slow down th...
