A STUDY OF THE REFERENCE CLIMATIC PARAMETERS AND THEIR IMPACT UPON THE HYDROLOGICAL REGIME. CASE STUDY: IALOMITA HYDROGRAPHIC BASIN
Journal Title: Present Environment and Sustainable Development - Year 2009, Vol 3, Issue 3
Abstract
The paper provides an analysis for the evolution and spatio-temporal variation of two climatic parameters (precipitation and evapotranspiration) and one hydrological parameter (the flown water volume) over a common period of time (1970-2007) in Ialomita Hydrographical Basin which has been recently affected by extended periods of drought. In achieving this aim we started our analysis from the equation of the water balance in a large hydrographical basin over a long period of time. Among the elements of this equation the amount of rainfall (precipitation) and evapotranspiration are further called the reference climatic parameters since they are the ones that influence the volume of the surface run-off. The evolution of the above mentioned parameters has been accomplished by taking into account the recorded data from 6 meteorological and hydrological posts that can be considered characteristic for Ialomita River Basin. They have been used to identify the tendency of these reference climatic parameters and establish their influence upon the hydrological regime. The parallel study of these three parameters may offer valuable data upon their tight connection in a regional context.We often use the air temperature as an indicator of how comfortable we will feel when we are involved in sports or other physical activities. However, the air temperature is only one factor in the assessment of thermal stress. Human thermal comfort depends on environmental and personal factors. The four environmental factors are: airflow (wind), air temperature, air humidity, and radiation from the sun and nearby hot surfaces. The personal factors are the clothing being worn and the person's level of physical activity.
