Sustaining or improving base flow
Vegetation can intercept precipitation, slow surface water runoff, and increase temporary storage of groundwater in soils, floodplains, and riverbanks, which is later released slowly during the dry season to increase the magnitude and permanence of flows. low.
To determine the base flow, it is common to measure the rainfall on the surface, to estimate the infiltration, redistribution, evaporation and percolation of the waters through the unsaturated zone. However, it is common to get errors due to the uncertainty of the soil parameters, which can easily produce errors in the storage-discharge relationship of groundwater.

RIOS introduces a science-based approach to prioritizing watershed investments by identifying where protection or restoration activities are likely to yield the greatest benefits for both people and nature at the lowest cost. RIOS can facilitate the design of investments for a single management goal or several at once, including erosion control, water quality improvement (for nitrogen and phosphorus), flood regulation, groundwater recharge, dry season water supply, and terrestrial and freshwater biodiversity
