Abstract:
In the investigation and design stage of hydrological projects meteorological data plays an important role, and provides valuable information, therefore, the investigation of hydro-meteorological parameters is very important. In the investigation and design stage of water resources pro-ject, the hydro-meteorological data provides following in-fo rnati on.
(i) Direct climatological data give valuable informa-
tion such as (a) wind data for loading on structure, (b) temperature, radiation and humidity data for durability of materials.
(ii) Stastical analysis of meteorological data gives the information which has been required for the hydro-logical project, such as the information on the nature of stastical distribution of the element so that the frequency of occurence or certain events can be estimated as well as the probable extremes.
(iii) Estimate probable conditions when relevant hydrolo-gical data is not available. Knowledge of the physical relationships between elements with time and space enables interpolation to be done, and relationship can be established by stastical corre-lation.
