The combined impacts of woody plant encroachment and climate variability have the potential to alter water balance in many sagebrush steppe ecosystems Western USA, leading reduced availability these already water-scarce regions. This study compared water-balance characteristics two adjacent semiarid watersheds central Oregon, USA: one dominated by big western juniper. Precipitation, springflow,...

Studies examining potential evapotranspiration (PET) for a mature forest reference compared with standard grass are limited in the current literature. Data from three long-term weather stations located within 10 km of each other in the USDA Forest Service Santee Experimental Forest (SEF) in coastal South Carolina were used to (1) evaluate monthly and annual PET estimates from five different met...

Seeking to contribute with the management of water resources in Itaipu Binacional reservoir region, this research aimed characterize dynamics evapotranspiration and evaluate performance different mathematical methods, which determine reference (ETo) from air temperature values. Fifteen municipalities were analyzed. After obtaining data series, ETo was estimated using six methods: Camargo (C), H...

Abstract One of the significant components hydrological cycle is evapotranspiration. Monthly meteorological parameters 35 years from 19 stations across Northern Region Nigeria (NRN) were obtained and utilized for calibration Hargreaves–Samani (HS) model by comparing between potential evapotranspiration (ET o ) values estimated original HS Penman–Monteith (FAO-56 PM) models. The calibrated equat...

The aim of this study was to analyze the water demand in banana, papaya and coconut crops grown irrigation districts Araras Norte Baixo Acaraú, located State Ceará. A historical meteorological series regions where from are used. Precipitation, maximum minimum temperatures, relative humidity data were obtained these series. From acquired precipitation data, frequency intensity dry rainy years ar...
