3H and 14C as tracers of ground-water recharge 3H and 14C as tracers of ground-water recharge

Surface spreading of water from the Santa Clara River is used to recharge aquifers underlying the Oxnard Plain. These aquifers are divided into an upper system about 400 feet thick, and a lower system more than 1,000 feet thick. In previous studies, it has been reported that surface spreading recharged aquifers in both the upper and lower systems. Water from most wells perforated in the...

A semi-implicit finite difference model for three-dimensional tidal circulation, A semi-implicit finite difference model for three-dimensional tidal circulation,

A semi-implicit finite difference formulation for the numerical solution of three-dimensional tidal circulation is presented. The governing equations are the three-dimensional Reynolds equations in which the pressure is assumed to be hydrostatic. A minimal degree of implicitness has been introduced in the finite difference formula so that in the absence of horizontal viscosity the...

Approach to data exchange: the spatial data transfer standard Approach to data exchange: the spatial data transfer standard

Significant developments have taken place in the disciplines of cartography and geography in recent years with the advent of computer hardware and software that manipulate and process digital cartographic and geographic data more efficiently. The availability of inexpensive and powerful hardware and software systems offers the capability of displaying and analyzing spatial data to a...
