Trends in precipitation and stream flow in the semi-arid region of Atrak River Basin, North Khorasan, Iran
In this paper trends of precipitation and stream flow are analyzed in the Atrak River basin in the North Khorasan province. Normal score linear regression, Mann-Kendall, and Seasonal Kendall trend tests were adopted. Three precipitation variables and two stream flow variables including total precipitation, maximum daily precipitation, and number of rainy days, mean discharge and peak discharge ...
متن کاملEvaluation of meteorological, hydrological and groundwater resources indicators for drought monitoring and forecasting in a semi-arid climate
Drought as a natural phenomenon characterized by a significant decrease of water availability during a period of time and over a large area. In recent years, droughts and its frequent in arid and semi-arid regions like Iran on the one hand, and water demand has been rising on the other hand and, as a result, their impacts are being aggravated. Therefore, the meteorological and hydrological...
متن کاملThe Hydrogeology and Water Supply Problems in North - Central Chile !
The north-central zone of Chile is described with respect to groundwater supply problems. In this region, groundwater is almost exclusively obtained from the thin alluvium in the main transverse valleys, which descend from the Andes in those sections where the valleys cross the northerly trending "central valley." Because of the steep groundwater gradients prevailing, the groundwater resources ...
متن کاملCatchment-scale spatial variability analysis of soil hydro-physical properties in a semi-arid region of Iran
Soil hydrau-physical data are important for many hydrological modelings. They are the main variables controllingthe key processes such as water and chemicals movement and transport in the soil profiles. This study was conductedin order to analyze the spatial distribution of selected soil hydrau-physcial characteristics including infiltration rate(IR), saturated hydraulic conductivity (Ks), bulk...
متن کاملForecasting Crop Water Requirement By Et-Hs model For Arid and Semi Arid Region of Iran
Estimating actual crop water requirement and irrigation schedule are essential for designing of the irrigation systems, storage construction and water conveyance structures. Many models have developed for estimating crop water requirement. Although most of these methods need different climatic parameters, providing and forecasting all of these parameters always are not available. Most of the ti...
