Using hydraulic head, chloride and electrical conductivity data to distinguish between mountain-front and mountain-block recharge to basin aquifers

Mountain-Block Hydrology and Mountain-Front Recharge

In semiarid climates, a significant component of recharge to basin aquifers occurs along the mountain front. Traditionally called “mountain-front recharge” (MFR), this process has been treated by modelers of basins as a boundary condition. In general, mountain-front recharge estimates are based on the general precipitation characteristics of the mountain (as estimated, e.g., by the chloride mas...

WATER ABOVE THE MOUNTAIN FRONT – ASSESSING MOUNTAIN-BLOCK RECHARGE IN SEMIARID REGIONS By

Mountains provide as much as 90-100% of the freshwater to surrounding basins in arid and semiarid regions because of their distinctive and complex topography, and the consequent effects on precipitation (P) and evapotranspiration (ET). One of the primary objectives of this dissertation is to estimate mountain-block recharge (MBR), an important component of the mountain contribution to groundwat...

NMR Logging to Estimate Hydraulic Conductivity in Unconsolidated Aquifers.

Nuclear magnetic resonance (NMR) logging provides a new means of estimating the hydraulic conductivity (K) of unconsolidated aquifers. The estimation of K from the measured NMR parameters can be performed using the Schlumberger-Doll Research (SDR) equation, which is based on the Kozeny-Carman equation and initially developed for obtaining permeability from NMR logging in petroleum reservoirs. T...
