The Elephant Butte Irrigation District desired the construction of a small-scale hydrologic model located in the southern Rincon Valley within the EBID (Rincon Model) using MODFLOW with the Farm Process (MF-FMP). The purpose of the model is to obtain a tool to demonstrate an MF-FMP model on a pilot project scale before adopting MF-FMP for a regional model encompassing the entire EBID and to illustrate how MF-FMP can simulate (a) un-metered historic pumpage, (b) impacts of surface-water and groundwater abstraction on Rio Grande stream and return flow, and (c) scenarios of changing allotments influence deliveries and downstream stream gains/losses.
