Document Summary
Insects as diverse as dragonflies, mayflies, mosquitoes develop as larvae in streams: fish consume aquatic insects, and birds such as kingfishers, herons, ospreys dine on fish, many amphibians spend their larval stages in streams and some live forever. Lakes and ponds are ecologically diverse systems: are bodies of open standing water, their physical conditions and the types of life within them vary with depth and the distance from shore. Groundwater plays key roles in hydrologic cycle: we can approach the hydrologic cycle from a systems perspective, reservoirs: ocean; ice caps and glaciers; and then groundwater, processes: precipitation, surface runoff, in ltration, percolation, evaporation, transpiration, fluxes: The global hydrologic cycle maintains mass balance total amount of water is xed. Aquifer"s upper layer/zone of aeration: contains pore spaces partly filled with water. Water table mimics topography: where water table intersects surface = surface water. Recharge = water ows into an aquifer via precipitation/in ltration.
