urban synergetics lab using D3/Skeleton- Skeleton documentation.
The first visualisation was derived by using the Attribyte DATA_Val ( which represents the average mean value of depth of all the wells combined in that state w.r.t the sea level)
From the first graph we can conclude that the states with the largest depth in well water levels are :- WY; CO; CA; KS
The Second visualisation was derived by using the Attribyte STAGE ( which represents the mean FLOOD Level Stage or the point at which the well is said to have surplus water) of all the wells combined in that state w.r.t the USGS Flood Level Water Scale)
From the second graph we can conclude that the states with the largest depth in well water levels are :- CO; NM; WY; MT
The map depicts streamflow conditions as computed at USGS streamgages. The colors represent real-time streamflow compared to percentiles of historical daily streamflow for the day of the year. Here each Point size is determined by the Water Level whcih helps us visualise the areas impacted
The Data considerd to visualise this graph is between the months of December 2018 - February 2019 ; which is during the occurance of the Hurricane Florence which took place on the east Coast
The fourth Visualisation represents the Comparison between the No of records(Wells) collected and also the arranged according to the category of Percentile into which they fall .
From the above Visualisations we can infer that there is a corelation between the occurance of a hurricane and the ground water levels as the water levels inside wells on the East coast which came under the areas which were influence by the Hurricane Florence are higher than the wells on the West Coast
Formatted output is returned for each site that meets the filter criteria. Each site grouping contains the following elements:

site_no |
Each site in the USGS data base has a unique 8- to 15-digit identification number. Site numbers are assigned based on this logic. You can search using an exact match or match using a partial site number. To use an exact match you must include all of the digits including any leading zeros (0) that make up the complete site number. A site will not be found if the site number has a leading zero and it is not included in the string tested using an exact match. |

In the United States, watersheds have been numbered since the 1970's using an 8-digit system known as a "Hydrologic Unit Code" (HUC). |

|
flow |
Is the volume of water flowing past a given point in the stream in a given period of time. For periods where flow is replaced by a status code see the following reference for additional information on status codes. |
114 |
|
flow_unit |
A rate of the flow, in streams and rivers, for example. It is equal to a volume of water one foot high and one foot wide flowing a distance of one foot in one second. One "cfs" is equal to 7.48 gallons of water flowing each second. |
cfs |
|
flow_dt |
Is the measurement date and local standard time of the flow element. |

|
stage |
Is the height of the water in the stream above a reference point (also known as gage height). Gage height refers to the elevation of the water surface in the specific pool at the streamgaging station, not along the entire stream. Gage height also does not refer to the depth of the stream. Measurements of gage height are continually recorded by equipment inside a gagehouse on the streambank. For periods where stage is replaced by a status code see the following reference for additional information on status codes. |

|
stage_unit |
Is the unit used in the measurement of the stage element. |
ft |
|
stage_dt |
Is the measurement date and local standard time of the stage element. |
