<br />programmed to activate at even lS-minute intervals to record a data measure- <br />ment. The DCP then computes a transmit interval utilizing a random number <br />generator. This interval is between 2 and 10 minutes. If a 6-minute interval <br />is utilized, the random transmission will be made at 1421 hours. The elapsed <br />time from event occurrence to transmission of data is 13 minutes. Scenarios <br />could be given which would give a minimum elapse time of two minutes or a <br />maximum elapse time of 24 minutes. In addition, a random transmission occur- <br />ring on channel 118W has approximately a 20% chance (with current channel load <br />levels) of not being received due to interference with another random trans- <br />mission being sent at the same time. <br /> <br />. <br /> <br />F. Future Applications <br /> <br />Any data that can be collected remotely can be monitored by the <br />satellite-linked monitoring system. Future applications, based primarily on <br />current sensor capabilities, are likely to be in the areas of runoff' forecast- <br />ing, water quality monitoring, and in irrigation planning. Runoff forecasting <br />will require the addition of sensor configurations capable of monitoring <br />liquid and frozen precipitation, air temperature, solar radiation, and soil <br />moisture. Water quality monitoring covers an extremely wide spectrum but <br />would likely consist of a sensor configuration capable of monitoring conduc- <br />tivity (total dissolved solids), water temperature, dissolved oxygen, and <br />turbidity. Irrigation planning would require a sensor configuration capable <br />of monitoring humidity, precipitation, soil moisture, soil temperature, air <br />temperature, wind velocity and azimuth, evaporation rates, and solar radiation. <br /> <br />The addition of a DECTALK unit to the system will make the data base more <br />accessible to the general public. Real-time flow data will be available from <br />any phone by computer-generated voice-synthesized message. <br /> <br />-55- <br />
