This document discusses water erosion, which is the removal of soil by water. It defines erosion as the detachment, transportation, and deposition of soil. The main causes of erosion are misuse of land, deforestation, and poor soil management. The agents of erosion are wind, water, temperature, and biological factors. Water erosion specifically refers to the removal of soil particles by rain or flowing water. The forms of water erosion are rain splash, sheet, rill, gully, and stream erosion. Climate, soil properties, and topography affect the rate of water erosion.

water erosion is the detachment, transportation and deposition of soil particles from one place to another by the force of water
Soil erosion by the water is the result of rain detaching and transporting of vulnerable soil, either directly by means of rain splash or indirectly by rill and gully erosion.

Soils can process and hold considerable amount of water. They can take in water, and will keep doing so until they are full, or until the rate at which they can transmit water into and through the pores is exceeded. Some of this water will steadily drain through the soil (via gravity) and end up in the waterways and streams, but much of it will be retained, despite the influence of gravity. Much of this retained water can be used by plants and other organisms, thus contributing to land productivity and soil health.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Water erosion
1. WATER EROSION
Muhammad Nadeem Ashraf
Student, Soil & Environmental Science
Faculty of Agriculture, Rawalakot
2. EROSION
“Removal of soil from its original position”
Or
“It is the process of detachment,
transportation & deposition of soil
materials from one place to another by
erusive agents”
8. Water Erosion
“ It is the detachment, transportation & deposition
of soil particles by the force of water from one
place to another.”
Soil erosion by water is the result of rain
detaching & transporting of vulnerable soil,either
directly by means of rain splash or indirectly by
rill & gully erosion.
9. Forms of water erosion
A). Rain Splash Erosion:
Rain splash erosion is caused by the impact of
water striking the surface of soil.
It takes place in two steps.
1. As precipitation fills the pore spaces, loosening
& driving soil particles apart.
2. Impact of subsequent rain drops hitting the
surface, transporting particles to other area.
12. B) Sheet Erosion.
“ It is the uniform removal of soil in thin
layers in sloping land resulting from rain
splash erosion.”
surface runoff forms when the rainfall
intensity of a storm exceeds the infiltration
capacity of soil.
14. C) Rill Erosion.
It is caused by water concentrating into
innumerable, closely spaced small
channels. Left unchecked, rills can cut
vertically & horizontally and when joined
form gullies.
17. D) Gully Erosion.
Gullies are steep-sided trenches formed by
the coalescence of many rills.Once they are
started difficult to stop.
Stages of gully erosion.
Stage-1. Cutting top soil.
Stage-2. Enlargement of gullies.
Stage-3. Healing stage.
Stage-4. Stablization.
22. Factors affecting water Erosion
A) Climate.
1. Precipitation.
2. Temperature.
3. Wind.
4. Humidity.
5. Solar radiation.
23. B) Soil.
1. Physical properties of soil.
2. Vegetation cover.
3. Organic matter contents in soil.
4. Moisture contents of soil.
5. Soil density
C) Topography.
