Hydrological and hydrogeological systems are networks that concentrate and funnel fluids to outlets. Plants adapt to the availability of water: Hence, plant communities concentrate along channels, flow paths, depressions and discharge areas and consume water that was recharged upstream. As a result net recharge decreases with increasing catchment size by secondary evaporation. These feedbacks also complicate basin response to climate changes. Higher rainfall and higher recharge can result in an expansion of discharge zones and in an adaptation and increase of vegetation density therein. | Hydrological and hydrogeological systems are networks that concentrate and funnel fluids to outlets.
