Variability of streamflow and precipitation in Washington [Kresch, David L.] on *FREE* shipping on qualifying offers. Variability of streamflow and precipitation in WashingtonAuthor: David L. Kresch. To understand changes in streamflow components in the context of climatic variability, streamflow trends were compared to the trends of several precipitation metrics (Table 1 and Fig.

Statistically significant decreasing trends in annual precipitation were observed in four watersheds (Fig. 3 e), ranging from − mm/yr to − mm/: Christine A. Rumsey, Matthew P. Miller, Graham A. Sexstone. Introduction. Climate and land use are two important factors that influence hydrological responses of a river.

Climate variability can impact flow routing time, peak-flows and volume by affecting the amount and distribution of regional precipitation and temperature (Changnon and Demissie,Schulze,Wang et al., b), while land use changes can cause changes in baseflow, annual Cited by: Read chapter 3 Climate and Hydrology of the Colorado River Basin Region: Recent studies of past climate and streamflow conditions have broadened understan.

This study presents a comprehensive assessment of the variability and trends of the precipitation and temperature along with the trends in drought indices over the State of California. The non-parametric Mann–Kendall trend test is applied with a trend-free pre-whitening procedure in trend identification.

International Journal of Cited by: To this end, this study models the relationship between teleconnection patterns and streamflow by considering a spatial domain (°E–°E, 32°N–40°N) from the Korean Meteorological Administration (KMA.

; Oh and Moon, ) to enable a subjective separation of typhoon and non‐typhoon seasonal precipitation and by: The goal of this work is to assess climate change and its impact on the predictability of seasonal (i.e., April–July) streamflow in major water supply watersheds in the Sierra Nevada.

The specific objective is threefold: (1) to examine the hydroclimatic impact of climate change on precipitation and temperature at the watershed scale, as well as the variability and trends in the predictand (i Cited by: 2.

Understanding of precipitation and streamflow variability on these extended time scales is developing (e.g., Probst and Tardy, Lettenmaier et al.MarengoCayan et.

Year Published: Spectral analysis to quantify the response of groundwater levels to precipitation—Northwestern United States.

Persistent atmospheric patterns that lead to wet and dry seasons and droughts over periods of months to decades and longer-term climate change over periods of decades to millennia affect groundwater resources.

Note: The majority of climate models run for WW are projecting changes to annual precipitation that do not deviate largely from our region’s historical climate. This means natural variability is expected to play a larger role in precipitation trends into the future than forcing from GHGs.

On the whole, a 66 % of total decline in streamflow was observed due to human activities and 34 % due to climate variability. Most reduction in streamflow (59 %) due to climate variability was. UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON: For sale by Book and Open-File Report Sales U.S.

Climatic variability and flood frequency of the Santa Cruz River, Pima County,Cited by:   The relative sensitivities of low streamflow to precipitation and temperature changes have important implications for adaptation planning because global circulation models produce relatively robust estimates of air temperature changes but have large uncertainties in projected precipitation amounts in the Pacific Northwest U.S.

Improvements were greatest for models including parameters describing interannual variability in measured base flow (median August temperature) or measured streamflow (median July temperature, July or August daily range) at the HUC6 scale and with the inclusion of modeled average streamflow for median July temperature (Table 6, ΔAIC = Author: Naomi E.

Detenbeck. This study aims to provide a mechanistic explanation of the empirical patterns of streamflow intra-annual variability revealed by watershed-scale hydrological data across the contiguous United States.

The Alabama River, for which the model overestimated streamflow, showed marked improvements during both the calibration and validation periods, with relative bias reduced to ‐% and % from % and %, respectively.

The calibrated model accurately reproduced the magnitude and variability of annual by: 1. Changes in the seasonality and timing of annual peak streamflow in the north-central USA are likely because of changes in precipitation and temperature regimes.

A source of long-term information about flood events across the study area is the U.S. Geological Survey peak streamflow database. However, one challenge of answering climate-related. Chapter 2. Current Understanding of Colorado River Basin Climate and Hydrology 43 Key points • On average, about million acre-feet (maf) of precipitation falls over the Colorado River Basin annually, but only about 10% (17 maf) becomes natural streamflow available for use.

Garfoot Creek drains mi 2 upstream from the streamflow-gaging station near Cross Plains (fig. 1), and the stream channel is mi long from the station to the stream headwaters. The overall channel slope is 97 ft/mi, and the channel slope between the and 85.

Environmental and Societal Impacts Group. Additionally, summertime precipitation is predominately convective in this area and is responsible for a large portion of summer streamflow variability. Streamflow typically increases by 50 to percent of baseflow for moderate rainfall events for periods of up to one : J.

H. Copeland. Analyses of long-term records at 35 headwater basins in the United States and Canada indicate that climate change effects on streamflow are not as clear as might be expected, perhaps because of ecosystem processes and human influences.
