In southwest Kansas, the water cycle is shaped by scarce rainfall, high evaporation, and a strong dependence on groundwater. Precipitation either evaporates, supports vegetation, flows briefly through draws and streams, or infiltrates the soil; a small portion then percolates downward through permeable sediments to recharge local aquifers, including the High Plains Aquifer. That stored groundwater then sustains wells, springs, and riparian areas.
Rain that can’t soak in fast enough flows downhill across the surface into ditches, creeks and streams. Steep slopes, tight clay soils and hard downpours all push this share up, and runoff often carries loose soil and pollutants with it.
Water that turns to vapor straight from wet ground, puddles and leaf surfaces before it can soak in. In a semi-arid climate, sun, wind and dry air claim a large share of every storm, so it is set here as a fixed climate condition rather than a slider.
Water that soaks into the ground through the pore spaces between soil grains. Open, sandy soil and flat ground let more in; tight clay and steep slopes let less in. Once underground it takes one of two paths: back up through plants, or down toward the aquifer.
Soaked-in water that stays in the root zone and returns to the air. Roots pull it up, and leaves release it as vapor (transpiration), while some evaporates from the soil itself. In dry climates, most of the water that infiltrates ends up here.
Water that slips past the roots, trickles down through the unsaturated zone and reaches the water table, refilling the aquifer. It is the smallest and slowest path. Where the water table sits deep, the trip can take years or even decades.
