VECTOR Systems for Basic Water Resources Monitoring
Good predictive modelling requires good quality data. In the absence of such data you are faced with two options: either build a model with sketchy, incomplete field data that you perhaps didn't collect, or forego a model altogether and just make do with an "educated guess" of what the future may hold. HydroTechnics offers a modern alternative. With a VECTOR System, resource monitoring instantly becomes simple, clear, and and intuitive and when coupled to surface resource monitoring sensors or networks,
anything is possible.
- Within saturated zones under intermittent surface water bodies: Quantify and correlate contributions to the subsurface as a function of seasonal surface water availability (i.e. subsurface effects of gaining or losing streams, retention ponds, catchment basins, spreading ponds, treatment lagoons)
- Between well field and recharge zone: Observe ground water vector changes as a function of pump location and seasonal pumping schedule.
- As part of intensively monitored environmental networks: Couple surface water measurements, rainfall, temperature, soil moisture, and vegetation properties to ground water vector properties. Augment BASIN data with "subsurface environment" trends for more comprehensive watershed modeling.
- Salt water intrusion monitoring: Monitor movement rates of "subsurface environment" trends for more comprehensive watershed modeling.
- Determination of recharge rates: Effectively quantify recharge by observing short/long term ground water pulse velocity, direction, and duration.

- Well head protection zones: Determine zones of influence and perform vector manipulations accounting for background flows and their seasonal fluctuations.
- Determination of watershed protection zones: Quantify ground water flow directions independently of surface topographic driving forces.
- Verification of transient ground water velocity fields: (as model input parameters)
- Resolving seasonal influences to wetland subsurface dynamics
- Local/regional surface climatic effects on field-scale saturated flow environments
- Determine and verify irrigation/pumping and ground water cycling geometries
- Monitor subsurface flow rates and directions near dams and other surface water impoundments: Observe relationships between lake level and ground water vector.
- Induced surface water infiltration to the subsurface: Monitor effects of surface flooding to counteract land subsidence from ground water mining.
- Verification of isotope-obtained ground water age and source location
- Vertical/horizontal aquifer zone communication Localized effects from large, dewatered excavations: Monitor effects in unconso-lidated material aquifers near mine dewatering, pumped construction excavations, building foundation installations and other ground water diversions.
- Ground water injection and storage loss directions and velocities: Determine loss rate and direction within ground water "banks".
- Ground water mixing through aquitards

- Direct measurement of Hydraulic Conductivity: Establish this basic aquifer parameter in confined or unconfined aquifers using unambiguous, directly observed flow velocity data and without generating discharge from pump testing. Use vector subtraction to calculate various radial anisotropies using well head measurements and selective drawdowns.
- Changes in Hydraulic Conductivity from biofouling: Couple velocity changes, chemistry, and head measurements over time to observe changes in Hydraulic Conductivity as a function of biofilm build-up within an aquifer.
- Contributions and directions of recharge and discharge mechanisms
- Predict locations of stagnation zones and ground water divides
- Better quantification of modelling uncertainties
- Better calibration of model parameters
- Verification of stochastic flow assumptions: Observe and map the distribution and spatial variability of Hydraulic Conductivity without aquifer testing and dubious, chart-derived K values. Determine aquifer heterogeneity and hydraulic anisotropy scales in well penetrated field sites.
- Sedimentary property correlation: Link particular flow properties to the sediments in which they occur.
- Track contaminant plume migration: Predict future positions of specific chemistry. Back calculate likely contaminant source locations and ages.
