Study of Infiltration Rate Name: Jemel Joseph Class: 6 1 S Date: Candidate No. : Statement of Purpose of Investigation The purpose of this study is to measure the infiltration rate of four (4) sites which were visited on our field trip to Cedros. Site 1 being the environment disturbed by man‚ soil compacted by actions of man and animals. Site 2 being the environment waterlogged‚ because of the mangrove present. Site 3 being the environment undisturbed by man‚ with vegetation present

The concept is very similar to sudden expansion in pipe flow‚ except that hydraulic jumps occur in open-channel flow. At

within the rock is encouraged‚ leading to increased infiltration. This will cause subsequent percolation and larger groundwater stores and baseflow‚ so that discharge contributed to the channel is significantly reduced. Discharge occurs via the emergence of throughflow and baseflow‚ hence the longer lag time owing to time taken for water to maneuver through soil particles. e.g. carboniferous limestoneConversely‚ impermeable rocks inhibit infiltration as water has very few openings to seep into.

Technique Equipment Description Justification (Why we did it – what would the results tell us?) Infiltration rate • Single ring Infiltrometer • Ruler • Water • Hammer • Measuring Tape • Stopwatch • Bucket First‚ a measuring tape was placed down along the 15m beach transect. Every 5 meter/15cm in diameter was hammered in to the wave cut platform. A bucket of water was then collected from the beach and poured into a 20cm high single-ring infiltrometer. We timed (with a stopwatch) how much

slope can also affect flows to and within a river channel. Flows to and within a river channel also include overland flow‚ infiltration‚ through flow and base flow. Overland flow is the movement of rainwater over land. It occurs when either the storm is too heavy for water to infiltrate into the soil‚ where the soil is impermeable or when the soil has become saturated. Infiltration is the downward movement of water through tiny pores in the soil. Through flow is the water reaching the river through the

(2 pts) Why are patients with cystic fibrosis prone to infections with Pseudomonas aeruginosa? Pseudomonas aeruginosa is an opportunistic infection that usually does not affect healthy patients‚ but is particularly detrimental in patients with cystic fibrosis. This is because they are antibiotic resistant to a certain extent. Paired with this‚ patients with cystic fibrosis have a decreased ability to produce mucous membranes‚ making it easier for biofilms associated with P. aeruginosa (Lyczak et

The unbalanced water distribution when water comes to the ground causing severe problems as flooding and erosion‚ destroying natural habitat and insufficient fill-in of water table. Porous pavement could increase the infiltration rate and interflow rate and reduce the overwhelmingly high rate

The amount of heat and moisture are gained from the building internal and external heat sources that is required to be removed by the building cooling system. Both heating and cooling loads form the basis in designing the HVAC systems for the building and occupied spaces to achieve both

How could the model be altered to include these processes? Answer = Precipitation and infiltration did not get represented. I don’t think it could be altered to include the these in the process without different specimens such as water‚ ice or even soil. 3. How would the “weather” be affected if the water was at a decreased temperature?
