Responses to Drought and Flooding02:41

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Applications of GIS: Disaster Management and Emergency Response

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...
Precipitation Gravimetry01:03

Precipitation Gravimetry

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
Precipitation Processes01:12

Precipitation Processes

The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...
The Water Cycle01:00

The Water Cycle

The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.
Precipitation and Co-precipitation01:17

Precipitation and Co-precipitation

Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Area of Science:

  • Environmental Science
  • Hydrology
  • Citizen Science

Background:

  • Distributed hydrologic measurements, such as baseflow, are costly due to equipment and personnel requirements.
  • There is a need for cost-effective methods to gather spatially and temporally distributed hydrologic data at the watershed scale.

Purpose of the Study:

  • To develop and evaluate a crowdsourced database for inexpensive, distributed stream stage measurements.
  • To assess the accuracy and viability of citizen scientist-collected hydrologic data.

Main Methods:

  • Implementing staff gauges with signs encouraging voluntary measurements via text message.
  • Establishing a server to store and display crowdsourced stream stage data.
  • Analyzing the accuracy of citizen scientist measurements and the overall data collection approach.

Main Results:

  • Crowdsourced data collection is a feasible supplemental method for gathering hydrologic information.
  • Citizen scientist participation in collecting stream stage data is promising.
  • The developed approach provides web-accessible hydrologic data.

Conclusions:

  • Crowdsourcing offers a cost-effective alternative for supplemental hydrologic data collection.
  • Citizen science initiatives can effectively engage the public in environmental monitoring.
  • This method demonstrates potential for expanding the reach of hydrologic data acquisition.
