Introduction What is a LiDAR Payload? LiDAR stands for Light Detection and Ranging and has become an increasingly prevalent technology over the past decade. NASA and meteorologists have used LiDAR, now embedded within cell phones with the release of the iPhone 12 Pro. LiDAR is commonly used in surveying, mapping, and inspection applications where it can provide very detailed and accurate ...
It presents unique challenges often concerned with permafrost dynamics, seasonal freezing and thawing of soil substrates, surface and subsurface hydrology, as well as climatology. ...
Rip rap is a common channel protection method because of its resistance to most flows with appropriate rock size; however, it does have significant drawbacks. Material can be expensive, not locally available, and placement requires heavy equipment. Additionally, rip rap channels are prone to regular maintenance, collection of debris and garbage, erosion at boundaries, undermining, and movement. ...
Firmer Soil From Root Reinforcement Root systems physically reinforce soil and resist erosion. ...
Rothamsted Research is the longest-running agricultural research institute in the world, with a history dating back to the middle of the 19th century. Sir John Bennet Lawes, an archetypal Victorian scientist, entrepreneur and benefactor, became interested in agricultural science after leaving Oxford University. On assuming responsibility for the family estate at Rothamsted (Harpenden, ...
Not having a water management plan tailored to the post-closure scenario can produce a host of ill-effects, including: Degradation of soil structure and fertility Hydrological changes Ongoing contaminant leaching problems from end-pit lakes and tailings Job losses and poverty Social service and infrastructure deterioration In many cases, mine closure ...
The extent of damage to water quality after a fire depends on a number of parameters, including: Geographical features and the size of the watershed The size and severity of the fire The time between fire and heavy rain The types of soil and plant life in the area The extent of erosion. More intense fires can severely damage watersheds by killing ground vegetation, ...
Hydrology databases make it possible to map, track and observe water resources. ...
The canopies of forests and other natural vegetation are important in watershed areas for replenishing groundwater and hydrology, so they need to be monitored. To find out more about canopy cover, consult the following sources: Mongabay’s introduction in What is the Canopy FAO about effects of plant cover STRI about effects of canopy cover of tree plantations ...
This collaboration enables us to meet public goals such as water safety, and to meet private objectives by developing commercial products of interest to a national and international market. How does Eijkelkamp Soil & Water make the difference? Eijkelkamp Soil & Water wants to use its expertise to contribute to development of this system since it ...
This rain gauge has been installed to determine the influence of rainfall on hydrological processes in the soil. Rainfall can decrease, for example, which would also reduce soil moisture, but such a reduction would not be caused by the tunnel construction. How does Eijkelkamp Soil & Water makes the difference? Eijkelkamp ...
Soil Hydrology with the Stevens HydraProbe Soil Sensor This year at the Meteorological Technology World Expo 2018 event in Amsterdam Stevens is excited to present a 2-hour Soil Physics Workshop. ...
On the other hand, if the soil moisture is 30% by volume, the sandy soil will dry out quicker than the clay rich soil and the clay rich soil will have a higher ET rate over a longer period of time. Soil Salinity Another factor that affects the plant transpiration is the salt content of soil. ...
These factors include pesticide use, soil characteristics, hydrology and climate. ...

Infiltration basins rely on the hydrologic capacity of the soil and the overall footprint to ensure the runoff can infiltrate in a timely manner. ...
Low Impact Development (LID) Best Management Practices (BMPs) such as bioretentions, green roofs, rain barrels, vegetative swales, and permeable pavements have been implemented to diminish the adverse effects of urbanization. In this study, a hydrological model for a Rainfall-Watershed-Bioretention (RWB) system is developed by using the Environmental Protection Agency Storm Water ...
This research has expanded to develop a relationship between soil moisture levels and the impact on meteorological and hydrological models and forecasts. ...
However, any land conversion will affect the water balance and hence solute fluxes within the soil column and connected ecosystems. Understanding the consequences of land conversion on soil hydrology is essential to support an economically viable agriculture while minimizing its environmental footprint. ...
This sensor is ideal for high-accuracy readings in water, soil, and air. The hydrology version is small enough to easily deploy through standard 1” (2.5cm) PVC conduit with 8” (20.3cm) factory bend corners, and offers a loop hole which can be used to mount weights or pull the sensor through pipes or other small areas. The soil version ...
