Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring
Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring
Timothy M Waring
“Wicked problems” are urgent, high-stake socioeconomic-environmental challenges that often involve ideological conflict and have no “best solutions.” Using examples from Maine’s Sustainability Solutions Initiative projects, Tim Waring describes how scientific models can be used to address these kinds of problems. When well-constructed and tested models are used to address policy-relevant issues, include input from stakeholders, and integrate social, economic and environmental dynamics, they can become “wicked tools” to address some of society’s biggest challenges.

The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.

Examining The Relationship Between Drought Development And Rapid Changes In The Evaporative Stress Index, Jason A. Otkin, Martha C. Anderson, Christopher Hain, Mark D. Svoboda
Drought Mitigation Center: Faculty Publications
In this study, the ability of a new drought metric based on thermal infrared remote sensing imagery to provide early warning of an elevated risk for drought intensification is assessed. This new metric, called the rapid change index (RCI), is designed to highlight areas undergoing rapid changes in moisture stress as inferred from weekly changes in the evaporative stress index (ESI) generated using the Atmosphere–Land Exchange Inverse (ALEXI) surface energy balance model. Two case study analyses across the central United States revealed that the initial appearance of negative RCI values indicative of rapid increases in moisture stress preceded the introduction …

Effects Of Runoff Sensitivity And Catchment Characteristics On Regional Actual Evapotranspiration Trends In The Conterminous Us, Il-Won Jung, Heejun Chang, John Risley
Effects Of Runoff Sensitivity And Catchment Characteristics On Regional Actual Evapotranspiration Trends In The Conterminous Us, Il-Won Jung, Heejun Chang, John Risley
Geography Faculty Publications and Presentations
An understanding of the role of hydro-climatic and geographic regimes on regional actual evapotranspiration (AET) change is essential to improving our knowledge on predicting water availability in a changing climate. This study investigates the relationship between AET change for a 60 year period (1951–2010) and the runoff sensitivity in 255 undisturbed catchments over the US. The runoff sensitivity to climate change is simply defined as the relative magnitude between runoff and precipitation changes with time. Runoff sensitivity can readily explain the conflicting directions of AET changes under similar precipitation change. Under increasing precipitation, AET decreases when runoff is increasing more …

Clarification Of Rubber Mill Wastewater By A Plant Based Biopolymer – Comparison With Common Inorganic Coagulants, Sumona Mukherjee
Clarification Of Rubber Mill Wastewater By A Plant Based Biopolymer – Comparison With Common Inorganic Coagulants, Sumona Mukherjee
Sumona Mukherjee
Background In this study, the efficiency of Guar gum as a biopolymer has been compared with two other widely used inorganic coagulants, ferric chloride (FeCl3) and aluminum chloride (AlCl3), for the treatment of effluent collected from the rubber-washing tanks of a rubber concentrate factory. Settling velocity distribution curves were plotted to demonstrate the flocculating effect of FeCl3, AlCl3 and Guar gum. FeCl3 and AlCl3 displayed better turbidity removal than Guar gum at all settling velocities. Result FeCl3, AlCl3 and Guar gum removed 92.8%, 88.2% and 88.1% turbidity, respectively, of raw wastewater at a settling velocity of 0.1 cm min−1, respectively. …

Center for Lakes and Reservoirs Publications and Presentations
In 2007, both zebra mussels (Dreissena polymorpha) and quagga mussels (Dreissena rostriformis bugensis) were found to have established populations west of the Rocky Mountains. The risk posed to the Pacific Northwest by the proximity of these new infestations is significant. This plan was developed in response to the increasing likelihood of the successful transport and introduction of these species into the State of Oregon and Pacific Northwest. Although prevention remains the most cost-effective means of addressing potential infestations of aquatic invasive species, if prevention efforts fail, the State of Oregon must be prepared to respond rapidly …
Road Cuts And Atterberg Limits Of Little Creek Road, Christopher A. Marquis
Road Cuts And Atterberg Limits Of Little Creek Road, Christopher A. Marquis
Natural Resources Management and Environmental Sciences
This senior project examined road cuts and soil adjacent to the road cut, along Little Creek road. Contrasting a landslide hillslope complex to a hillslope drainage complex, the project also compared the organic soil horizon to the mineral soil horizon in both soil units. The soils were analyzed using qualitative and quantitative measures of soil properties. The project utilized a road cut inventory to note the characteristics of the road cut such as presence of rill erosion, rock outcrop and sloping degree of the road cut. The project derived the plasticity index for both organic and mineral horizons, and compared …

Water Access And Security For Mongolian Peri-Urban Communities In The Face Of Climate Change And Development, Heather Cook
Water Access And Security For Mongolian Peri-Urban Communities In The Face Of Climate Change And Development, Heather Cook
Independent Study Project (ISP) Collection
The paper attempts to assess how water access and security in Mongolian ger districts is impacted by the competing forces of climate change and development. The development of Mongolia is, understandably, a priority of the government and much of the populace, as are the impacts of climate change, which are well documented and acknowledged. Furthermore, these processes both have potentially adverse impacts on the overall well being of communities. In the context of water access and security, the need to strike this balance becomes even more acute. These factors can all be seen playing out in the city of Sainshand, …

Inverse Method For Simultaneous Determination Of Soil Water Flux Density And Thermal Properties With A Penta-Needle Heat Pulse Probe, Changbing Yang, Masaru Sakai, Scott B. Jones
Inverse Method For Simultaneous Determination Of Soil Water Flux Density And Thermal Properties With A Penta-Needle Heat Pulse Probe, Changbing Yang, Masaru Sakai, Scott B. Jones
Plants, Soils, and Climate Faculty Publications
An accurate method for determination of in situ soil water flux density continues to be the most sought after and yet elusive hydrologic measurement. The penta-needle heat pulse probe (PHPP) employs a central heater needle surrounded by an orthogonal arrangement of four thermistor needles for two-component water flux density estimation. An analytical solution and inverse fitting method are presented for simultaneous estimation of thermal properties and soil water flux density using PHPP measurements. The approach yields estimates of both components of the flux in a plane normal to the axis of the PHPP needles. The method was evaluated using data …
