Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus. In the Pacific Northwest, low flow is defined as an annual phenomenon that occurs during the prolonged dry period, characteristic of the Mediterranean climate experienced in the region (WMO, Author: Vladimir Smakhtin.

Precipitation data from nine meteorological stations in arid oases of Hexi Corridor, northwest China during – were analyzed to detect trends in precipitation and Standardized Precipitation Index (SPI) at multiple time scales using linear regression, Mann–Kendall and Spearman’s Rho tests. The results found that annual precipitation in the observed stations was rare and fell into Cited by: 4. (ii) Thiessen Polygon Method: in this method the rainfall recorded at each station is given a weightage on the basis of an area closest to the station. Where, P 1,P 2 P n are the rainfall data of areas A 1,A 2 A n. The thiessen-polygon method of calculating the average percipitation over an area is superior to the arithmetic average method.

Eastern part of the Tauros mountain range. It drains an area of km2, which is shared by four countries (Table 1). About 54 per cent of the area lies in Iraq. The total length of the river is km of which km is in Turkey.

The mean annual rainfall in the basin is mm and precipitation decreases towards the south. The average. distinction between the response of rivers in areas of low precipitation and those in humid areas.

There is no clear evidence of the existence of higher, sediment yields or increased variability of annual yields in the former areas, but contrasts in sediment delivery and recovery response are apparent. of groundwater levels especially in the low precipitation areas served by canal irrigation.

Ground­ water balance analysis reveals obvious reasons for accretion of groundwater in marginal and saline districts. Vertical drainage appears to be a plausible solution to restrict the water table rise and to protect soils from secondary salinization.

Himalayan glaciers are the major source of fresh water supply to the Himalayan Rivers, which support the livelihoods of more than a billion people living in the downstream region. However, in the face of recent climate change, these glaciers might be vulnerable, and thereby become a serious threat to the future fresh water reserve.

Accurate spatial and temporal representation of precipitation is of utmost importance for hydrological applications.

Uncertainties in available data sets increase with spatial resolution due to small-scale processes over complex terrain. As previous studies revealed high regional differences in the performance of gridded precipitation data sets, it is important to assess the related Cited by: 5.
