Show CLIMATOLOGY AND HYDROLOGY By definition, climatology is the scientific study of climate, which is defined as the long- term manifestations of weather. Hydrology is the scientific study of the waters of the earth, especially with relation to the effects of precipitation and evaporation upon the occurrence and character of water in streams, lakes and on or below the land surfaces. The extremes in the physiography of the Great Salt Lake drainage basin directly influence various climatological and hydrological aspects of the area. These climatological concerns include both the macro- climate, weather considerations applying to the general area, and the micro- climate, considerations involving only the Lake itself. Hydrological elements include the water supply to the Lake, varying Lake elevation, physical properties of the Lake and the effect of the Southern Pacific Railroad causeway on the waters of the Lake. GREAT SALT LAKE DRAINAGE BASIN Location and Size The Great Salt Lake Drainage Basin is a 21,540 square- mile closed basin surrounding the Lake with the Lake as the terminal point. The boundary of the Basin, as shown in Figure 3, is formed by the drainage of the Bear, Weber, and Jordan Rivers plus intermittent surface drainage from areas northwest and southwest of the Lake. The Bear River rises on the northern slope of the Uinta Mountains in Utah at an elevation of about 11,000 feet. It flows in a 500- mile |
