1. Describe the interrelationship of the hydrologic cycle, streams, floods, and landslides. Water The volume of water that falls as precipitation in southeast Alaska averages more than 100 inches a year for the region. Despite the amount, most of this precipitation runs off the land into lakes and streams as surface water, and only a small amount filters into deeper layers as groundwater. The interrelationship of fresh water, surface water, groundwater, and the ocean systems—the hydrologic cycle—is shown in Figure 96. The earth's capacity to accept, store, and yield water depends on the type, size, number, and degree of interconnections that can store and conduct groundwater. The relative amount of water retained in, released to, or rejected from the ground depends on the nature and distribution of materials present in the shallow parts of the earth's crust. Sand and gravel store large amounts of water and transmit it readily. These permeable deposits are referred to as groundwater aquifers. Clay may contain as much or more water per cubic foot than sand and gravel, but it holds water in such small pores that it cannot be transmitted to wells in usable quantities—it is impermeable. Compact bedrock that contains water only in fractures is also impermeable. Impermeable material acts as a barrier to water movement through the ground. Copyright 1998-2004, UAA-ISER. Hydrologic Cycle ( Water Cycle ): The cycle of water movement from the atmosphere to the earth and back to the atmosphere through condensation , precipitation , evaporation , and transpiration . Hydrologic Cycle The description of the transport of water substance between the earth, the atmosphere, and the seas. Or In hydrologic terms, the natural pathway water follows as it changes between liquid, solid, and gaseous states
