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

CLASSIFICATION OF SOILS (IMPORTANT STATEMENT: These lecture notes are based upon BS5930:1999 and BS1377:1990 but‚ where appropriate‚ reference is made to “Eurocode 7 related documents”. These are namely BS EN ISO 14688-1:2002‚ BS EN ISO 14688-2:2004 and BS EN ISO 146891:2003). During this transitional stage as the full recommendations of the Eurocode are being implemented during 2010 students are advised to be aware that published text books are likely to make little reference to the Eurocode 7

In nature‚ organisms of all shapes and sizes greatly affect the ecosystems which surround them. As African elephants stomp through the savannah‚ pushing over trees and crushing shrubs‚ the forest is kept from overtaking their grasslands. The predatory nature of wolves in the Pacific Northwest prevents overpopulation as they hunt out rabbits and deer. While ecosystems rely on animals to maintain a healthy status‚ they also rely on the environment to keep from drastic change. However‚ glaciers all

Stratigraphy of the Jurassic Upper Jurassic The Upper Jurassic is described in the record by a low-relief transition from shallow-water into basinal facies (Winker & Buffer‚ 1988). Further‚ there is little to no evidence of seismic expression It has been documented that there are facies tracts from past basinal marine all the way to shallow marine as well as nonmarine in this area. In addition to this‚ the oldest confirmed Mesozoic sediments classified as marine in the province of the basin

Wadia April 01‚ 2013 Glazier Features Observed in Wayne County Ground Moraine (14‚000 to 24‚000 years old)- Ground Moraines often show up as rolling‚ strangely shaped land covered in grass or other vegetation. They don’t have the sharp ridges of other moraines. A ground moraine is made of sediment that slowly builds up directly underneath a glazier by tiny streams‚ or as the result of a glazier meeting hills and valleys in the natural landscape

Spatial distribution of gully head activity and sediment supply along an ephemeral channel in a southern Ethiopia‚ Arbaminch \ Abstract In this study‚ we examined the factors that control the spatial distribution of bank gully heads along a reach of an ephemeral river (Arbaminch‚ Ethiopia) in an area threatened by desertification in Southern Ethiopia. The activity of 58 gully heads was assessed in the field by pre-defined criteria such as sharp edges‚ presence of a plunge pool‚ tension cracks‚

Soil properties: Some physical and chemical properties of the soil were measured‚ which are presented in Table 1. The availability of nutrients and even contaminants depends on the degree of soil acidity. The most suitable pH for soil microorganism’ activity is 7‚ as nutrient solubility depends on soil pH changes (Riser-Roberts‚ 1998). The soil used in the present study has neutral pH and therefore does not limit the activity of microorganisms or the solubility of nutrients except for phosphorus

The area is also surrounded by many plate boundaries so it is a common place for many earthquakes and landslides to occur. The area is often in long periods of droughts followed by heavy showers. The area is covered with basin

Muriwai is located on the west coast of the north island New zealand and is approximately 40km from Auckland city‚ The two natural processes i am going to talk about that interact are long shore drift and Aeolian transportation and deposition. Long shore drift is a process where sediment is moved along a beach by the action of waves.When the waves approach a beach‚ the base of the waves drags along the sea bed picking up sediment and causing the wave to break‚ the wave then swashes up onto the

Rainfall simulations are important contributors to understanding infiltration and factors‚ which influence infiltration rate‚ such as bulk density‚ plant biomass and percent cover‚ and topography.
