The influence of some climatic parameters on dewatering of interior lakes of Iran

Earth's climate is one of the most important structural factors. Any anomalies in each of the components will cause irregularity and commotion in the whole system. The coefficient of variation of less precipitation is reagent stability and even time distribution. To examine the relationship between climatic factors and its effect on local lakes dewatering was used of the temperature and precipitation data of 50-year-old Asfazari database in cells 15 x 15 km. In addition to measurements of temperature and precipitation of central tendency, indexes used of dispersion indexes in statistical processes. Thresholds obtained show that the basin con ensures exit of the lake that to be the average temperature of less than 15.78, average annual rainfall more than 215 millimeters, snowy coefficient more than 13 percent, the coefficient of variation of precipitation less than 40 percent and the coefficient of variation of temperature more than 7.43. All basins inside Iran changed to a temperature not fit in the Quaternary. Status and evidence there are of lakes dewatering in the Quaternary do not match whit precipitation double and decline of temperature 6-12 degrees compared to the current conditions. So that line equilibrium of water and land could be the effects of the Quaternary terrace lacks by reducing 3, 9 and 12-degree temperatures and increased precipitation. Change the line equilibrium of water and, land cannot be interpreted with a temperature and precipitation changes alone and causality must search in changes of precipitation regime and geomorphology of the region.
