This document summarizes sediment and nutrient losses monitored at Soaring Eagle Dairy from 2004-2006. Key findings include:
- In 2005, a drought year, 1,000 lbs of sediment was lost, underestimating actual losses. Most sediment came from a plowed grass waterway.
- In 2006, a wet year, 1,000 lbs/acre of sediment was lost, mostly in a 3-day May runoff event. Phosphorus losses were 640 lbs (2 lbs/acre), mostly particulate.
- Nitrogen losses were 850 lbs (3 lbs/acre) in 2005 and 13,000 lbs (44 lbs/acre) in 2006, mostly as nitrates. Losses occurred

In recent years, Westport residents noticed that the salt marsh islands in the Westport Rivers, particularly in the West Branch, were disappearing rapidly. In response, the Westport Fishermen’s Association, the Buzzards Bay Coalition, the Marine Biological Laboratory Ecosystems Center, and the Buzzards Bay National Estuary Program partnered to measure the rate of salt marsh loss in the Westport Rivers and try to identify causes of this erosion
Land is a complex, multi-component natural entity that becomes a resource base when used for a specific purpose or purposes. Land degradation is a concept in which the value of the biophysical environment is affected by one or more combination of natural and human-induced processes acting upon the land. It is a temporary or Permanent decline in the productive capacity of land. It is also the reduction in the capability of the land to produce benefits from a particular land use under a specified form of land management. Major forms of land degradation are water and wind erosion, desertification and chemical erosion. Urban expansion is also a form of land degradation. Negative effects of land degradation affect heavily on environment and economy which is a cause of grave concern. Land degradation has significant costs, particularly in developing countries (Rosegrant and Ringler, 1991). It does not only reduces farm productivity affecting livelihood and regional economies, it also leads to reduced biodiversity. Land degradation in most developing countries is becoming a major constraint to future growth and development. About 40-75% of the world’s agricultural land’s productivity is reduced due to land degradation (IFPRI, 2001). Increased support for research and extension to increase crop yields is crucial to meeting the needs of a growing human population for food, biomass energy, fiber, and timber. There is a need to increase support to biodiversity preservation by alleviating pressure to convert remaining natural habitat to croplands. There is a need for more public investments to support SLM to slow land degradation.
This is the talk I gave at the Forest day, March 21 2016, at MUSE in Trento. I talked about the interaction between the water cycle, vegetation and climate. As a modeller, I conclude talking about the challenge of modelling all of this complexity at various spatial and temporal scales.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
1. Understanding Nutrient and Sediment Losses at Soaring Eagle Dairy - 5 Sediment and Nutrient Losses Eric Cooley and Dennis Frame UW Extension/Discovery Farms
2. Data The data presented in this presentation were provided by the U.S. Geological Survey as part of a cooperative agreement with the UW-Discovery Farms Program.
3. Monitoring at SED Monitored from December 2004 - October 2006 Field year = 12-months (Nov. 1 – Oct. 31) Always represents the year in which it ends Field year coincides with the crop year.
4. 2005 Field Year The first year November 2004 – October 2005 = drought year. Precipitation (ice, sleet and snow) was 21.7 inches, compared to the 30-year average of 30.5 inches for Manitowoc County .
6. Sediment losses Measured sediment losses represent only a portion of what occurred due to issues at the monitoring site. (see SED Part 4) There were events that occurred in March that caused significant soil erosion, but these events were not sampled.
7. 2005 Sediment loss The majority of sediment entering the monitoring site came from the area immediately north of the flume.
8. 2005 Sediment loss Sediment moved from the field adjacent to the station, which was plowed in the fall. Major contributing factor to loss was the accidental plowing of the grass waterway. Waterway was reseeded in the spring of 2005.
9. 2005 Sediment loss June 2005 after planting Field is not steep, but it does slope into an area of concentrated flow which then flows to the stream. Remainder of the year was dry with little runoff.
10. 2005 Sediment loss The lesson learned is that on these gently sloping fields in Northeastern Wisconsin, grassed waterways play a critical role in reducing soil erosion and sediment delivery to surface waters.
11. 2005 Sediment loss Data was not collected during the winter months because of frozen water conditions. Backwater subsided in early April and sampling started again. Remainder of the year was dry, with only a few small runoff events occurring.
12. 2005 Sediment loss The monitored events during 2005 produced approximately 1,000 lbs of sediment. yield of about 3.4 lbs/acre Values are greatly underestimated because the monitoring equipment was not working during the critical runoff periods.
13. 2006 Field Year To improve the site, the waterway was re-graded to create better getaway conditions.
14. 2006 Field Year Second year was much different than the first. 37.1” precipitation (ice, sleet, & snow) > 6” above the 30-year average Majority recorded in the spring (May 7.1”)
16. 2006 Field Year 2006 had a more complete monitoring record, but still issues. Water flowing under the wing wall. USGS was able to estimate discharge.
17. 2006 Field Year The computed sediment and nutrient losses listed are reasonable, based on the experience of the authors and USGS staff. About 1,000 lbs/acre of sediment passed through the flume. >99% lost during the non-frozen ground period
18.
19. 2006 Sediment loss A three day surface water runoff event that started on May 30, 2006, and ended June 2, 2006, accounted for 92% of the total sediment losses at this site.
20. 2006 Sediment loss Data from several Discovery Farms highlight the fact that large rainfall events at this time of year can produce very high levels of soil loss. Fields have been recently planted and therefore very vulnerable to soil erosion. Soil loss produced by a single runoff event can contribute the majority of the sediment losses for the entire year.
21. 2006 Sediment loss In seven years of on-farm monitoring, Discovery Farms measured large sediment losses from a single runoff event . This occurs under a wide variety of farming systems (no-till, minimum tillage, etc) and in all regions of the state. Though not desirable; agriculture is often at the mercy of weather conditions at this fragile time of year.
22. Phosphorus loss Phosphorus losses in 2005 are underestimated. Measured total phosphorus loss was ≈ 37 lbs 0.1 lbs/acre) 80% in the dissolved form
24. Phosphorus loss In 2006, ≈ 640 lbs (2 lbs/acre) of total phosphorus was measured. 28% occurred as dissolved
25. Phosphorus loss The increase in measured sediment losses in 2006 coincided with the increased level of particulate phosphorus losses. <10% of the total phosphorus was lost during the frozen ground period in field year 2006.
27. Nitrogen loss 2005 nitrogen losses are underestimated. Measured total nitrogen losses for 2005 were observed at nearly 850 pounds (about 3 lbs/acre). Majority (84%) of total nitrogen in the nitrate form
28. Nitrogen loss Runoff events in December 2004 had nitrate concentrations that ranged between 8 and 30 parts per million. Nitrate concentrations dropped to around 1 to 2 ppm when the site became operational again in spring.
29. Nitrogen loss Nearly 75% of total nitrogen losses occurred during the frozen-ground period.
30. Nitrogen loss In 2006, total nitrogen losses reached about 13,000 lbs (44 lbs/acre). Nitrate accounted for 87% of the total nitrogen losses (84% in 2005).
32. Nitrogen loss Concentrations ranged between 6 and 61 ppm Highest concentrations occurred on frozen-ground and in the early part of the spring runoff But, 70% of total losses occurred during the non-frozen period
33. Nitrogen loss 70% of total nitrogen losses occurred during the non-frozen ground period.
34. Conclusions In Northeastern Wisconsin the establishment and maintenance of grassed waterways in areas of concentrated flow cannot be over emphasized. Runoff in this section of the state has the potential to carry significant levels of sediment and nutrients to surface waters.
35. Conclusions Sediment losses occurred predominantly during non-frozen ground conditions. consistent with data collected on several other Discovery Farms. soil loss can occur during frozen soil conditions, but those losses are greatly influenced by tillage practices and the amount of concentrated flow running across the soil. Sediment losses produced by a single runoff event can contribute the majority of the sediment losses for the year.
