dc.description.abstract The present investigation, it aims to develop a model of groundwater recharge, using geoformations located in the headwaters of basin of the Jequetepeque River as recharging system. To do this, work was carried out pre-coordination with the authorities and the population in the area of influence to the study, the collection of information, geographical and geological letters and the purchase of materials. In the field, achieving the identification of geoformations concave, the collection of data of infiltration, measurement of flow, soil moisture and its density, sedimentation and erosion, geomorphological assessment and weathering. Then it is interpreted and consolidated the information through software programs and spreadsheets. For the investigation, it was determined an area of influence of 1 113 km2, which found 37 geoformations concave along the headland of basin. In the concave geoformations will generate two types of recharging: diffuse infiltration of infiltration and runoff. The geomorphology at the bedside of basin is variable; from flats, hills and hills, to steep slopes, which has an influence on infiltration, and water conservation in the form of either storages refills or deep subsurface. The results allow concluding that more than 70 %, of the rainfall occurring in the concave geoformations are sources of recharge of groundwater, which have been formed by interaction of natural processes geological, climatic and soil continued. The diffuse infiltration, presents a hydraulic conductivity between 0.04 to 0.17 cm/h and a flow of infiltration which is between 0.17 L/s and 12.3 L/s that feeds the aquifer. Contributions to the recharges are directly related to their area of influence. In the concave geoformation (A-01) is the natural recharge of 9 387.31 m3/year, which, by adding artificial recharges through conduction systems 28 067.04 m3/year, generates a total recharge of 37 454.35 m3/year, that if you do not exist the concave geoformations would be lost as runoff. Likewise, in basins without glaciers, there is a conditioning process of natural environment, forming water mattresses in a porous medium and a medium with infiltration secondary.
