when the South Jersey ResourceConservation and Development Council, Inc., was challenged toprovide a fast and convenient irrigation water management plan toarea farmers and, later, to areahomeowners, Campbell Scientific, Inc.,(CSI) quickly entered thepicture.  It was 1993 and the Council, a 501(c)(3) nonprofitorganization, was building the foundation for its ResourceInformation Serving Everyone (R.I.S.E.) network.  Thenet-work’s primary focus was, and remains, agricultural waterconservation, but grew into a multifunction undertaking when asecondary objective of fulfilling an Environmental ProtectionAgency (EPA) requirement for an in-kind local waterconservation project near a Superfund Site, and later an objectiveaddressing watershed modeling, were added.  R.I.S.E. stationsare currently distributed throughout eight of New Jersey’s11southern counties.  Now, with a total of 17 weather stationsand four water-quality stations spanning much of southern NewJersey, CSI remains at the heart of a system upon which watermanagers, farmers, homeowners, and researchers have learnedto depend.

Weather stations within the R.I.S.E. network are based around aCR10XMeasurement and Control System, which measures temperatureand humidity with a Vaisala HMP35C orHMP45C temperature andhumidity sensor, solar energy with a Li-CorLI200S or LI200Xpyranometer, wind speed and direction with a RM

R.I.S.E. station sites provide ample room forwheelchair access and allow school children the opportunity tostudy the network.

Young’s Wind Sentry Set, and rainfall with a TE525 or TE525WStipping bucket rain gage.  Sensors are measured every60seconds and output occurs hourly, every six hours, anddaily.  Conditional outputs document rainfall every sixminutes during an event.  Data are retrieved dailyvia telephone modems connected to each weather station. 

To maximize the benefits of the collected weather data, theCouncil incorporated the Penman-Monteith Evapotranspiration (ET)formula into each datalogger’s program.  This allows forthe approximation of the amount of water used by the turf undereach weather station.  Using crop coefficients developed byvarious researchers, and soil moisture numbers calculated by theUSDA Natural Resources Conservation Service, the user can develophis or her own irrigation water management concept for theirparticular agricultural crop.  These numbers can be found inthe Council’s web site athttp://www.sjrcd.org

Of particular interest to New Jersey researchers in watershedprotection and management, are the network’srainfall measurements.  More specifically, the six-minutesubset of rainfall is output during rain events.  Thatprovides our clients a detailed view of rainfall that wasnever before available. 

In response to the rapidly dwindling supply of fresh water, theCouncil was asked if the CSI system could help with a homeownerwater conservation program. Working with the local watercompany, United Water Toms River, the Council installed a CSIweather station and helped develop a lawn-watering program aimed athomeowners.  An ET amount and an approximation of minutes torun a hose-end or in-ground sprinkler system is pro-vided daily tothe local cable TV system, one radio station, and the localnewspapers.  This activity resulted in an approximate 1million gallon per day reduction in peak daily summer waterrequirements throughout this water system.

Once R.I.S.E weather stations record theirdata, customer-developed forms, including the typical SPLITparameter files found in CSI’s  PC208W software, make it manageableand easy to read. From its inception, the R.I.S.E. net-work hasgreatly eased South Jersey RC& D Council’s challenge ofproviding area farmers and homeowners with important informationrequired for effective  irrigation water management.  Thesystem, now easily accessed via the Internet, allows the Council togather instantaneous data for access by its many subscribersas well as to rebroadcast much needed irrigation information tolocal television, newspaper, and radio station audiences. Buildingon its initial goals, the South Jersey RC & DCouncil, Inc., has expand-ed into watershed monitoring in itspursuit of supplying useful, pertinent information to those whocan have an impact on resource conservation.  Findingweather data to be just part of its environmentalmonitoring needs, the Council expanded its presence by selectingCSI water-quality stations to provide related environmentaldata needed in the area.

Depth ranges from base flow of less than a footto 5 feet in storm events at this water quality station.  Theenclosure houses a CR10X, PS12LApower supply, phone modem, and VMTinterface.

 

Using a Campbell Scientific CR10X Measurement and ControlSystem, each water-quality station includes a VMT Water VelocitySensor, pH probe,OBS3Turbidity Monitor, Oxyguard Dissolved OxygenProbe, shaft encoder, Vaisala HMP45C Temperature and HumidityProbe,TE525WS Tipping Bucket Rain Gage, and a phone modem. Thesensor assemblage allows each station to contribute to a clearunderstanding of the hydrologic dynamics and man-made influences onthe Upper Cohansey Watershed in New Jersey’s Cumberl and County.

This map of New Jersey shows the location of the17 weather stations that comprise the R.I.S.E network, distributedthroughout eight of the state’s 11 southern counties. An additionalfour water quality stations are located on the UpperCohansey Watershed in Cumberland County.
