“…Had the IOI been damaged during either event, it could have resulted in millions of gallons of raw sewage discharging into Nogales Wash in Arizona. Previous studies in Ambos Nogales Norman et al (2008a) used the results derived from coupling urban growth and nonpoint source pollution models in a virtual environment to help make estimates of current conditions and future predictions under varying conditions using GIS, remote sensing, and a watershed approach. SLEUTH is a cellular-automaton model that predicts urban growth based on various growth rules, the pattern of urban cells, and the interaction of urban cells and their surroundings (Clarke and Gaydos, 1998;U.S.…”

“…These results are distributed spatially and the maps identifying hazardous areas are useful for planning purposes. The models were coupled to mimic denying growth of potential pollution sources using alternate scenarios to evaluate whether water quality predictions can be improved by curbing expansion to nonsource areas (Norman et al, 2008a). The results of this effort are meant to demonstrate the value of these models used in combination for water quality investigations and in the development of mitigation plans.…”

“…A planning scenario to increase water quality is described in Norman et al (2008a). In this research, high-risk erosion areas are eliminated within the urban growth model, SLEUTH, from possibility to urbanize, and instead are 'planted' with native grasses, while permitting the same amount of growth in more sustainable areas in the future.…”

“…This land-use dataset was modified to simulate the sustainable development zones and planted areas described in Norman et al (2008a) and K2 was rerun to register the impacts on runoff that these management actions would have. Results indicate that planning for sustainable development and planting in designated areas could decrease runoff volumes in the future at those hot-spot areas by both cities (Figure 9).…”

Appropriate land‐use, watershed‐management, and flood‐attenuation plans are critical in the cross‐border urban environment known collectively as Ambos Nogales. This paper summarizes methodologies for predicting the watershed response associated with land‐use change within a spatial and temporal context through the use of a hydrological model in a cross‐border setting. The KINEROS2 model is implemented via the Automated Geospatial Watershed Assessment 2.0 geographic information system interface to evaluate the watershed of Nogales, Arizona, and Nogales, Sonora, Mexico, to assess flood vulnerability by quantifying volumes of runoff and peak flow, based on alternative land‐use scenarios. Cross‐border geospatial data acquisition and input to models are described. Discussions about the KINEROS2 model results identify flood‐prone areas, simulate the impact of land‐use change, and evaluate the impact of potential flood‐control interventions in the Ambos Nogales watershed. Products from this research are being used in a comprehensive plan for sustainable development in Ambos Nogales.

“…Urban and non-urban land-use (i.e., population growth and shifts) will be modeled using the SLEUTH Urban Growth Model, that simulates transition of land-use using cellular automata and generates dynamic spatial patterns by applying growth rules to a grid of cells [51,52]. Each land-use state is modeled from local factors (e.g., roads, existing urban areas, topography), as well as temporal and random factors.…”

Using respective strengths of the biological, physical, and social sciences, we are developing an online decision support tool, the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM), to help promote the use of information relevant to water allocation and land management in a binational watershed along the U.S.-Mexico border. The SCWEPM will include an ES valuation system within a suite of linked regional driver-response models and will use a multicriteria scenario-evaluation framework that builds on GIS analysis and spatially-explicit models that characterize important ecological, economic, and societal endpoints and consequences that are sensitive to climate patterns, regional water budgets, and regional LULC change in the SCW.

Flood resilience in paired US–Mexico border cities: a study of binational risk perceptions

Disastrous floods in the twin cities of Nogales, Arizona, USA, and Nogales, Sonora, Mexico (collectively referred to as Ambos Nogales) occur annually in response to monsoonal summer rains. Flood-related hazards include property damage, impairment to sewage systems, sewage discharge, water contamination, erosion, and loss of life. Flood risk, particularly in Nogales, Sonora, is amplified by informal, “squatter” settlements in the watershed floodplain and associated development and infrastructure. The expected increase in precipitation intensity, resulting from climate change, poses further risk to flooding therein. We explore binational community perceptions of flooding, preferences for watershed management, and potential actions to address flooding and increase socio-ecological resilience in Ambos Nogales using standardized questionnaires and interviews to collect data about people and their preferences. We conducted 25 semi-structured interviews with local subject matter experts and gathered survey responses from community members in Ambos Nogales. Though survey response was limited, expected frequencies were high enough to conduct Chi-squared tests of independence to test for statistically significant relationships between survey variables. Results showed that respondents with previous experience with flooding corresponded with their level of concern about future floods. Additionally, respondents perceived greater flood-related risks from traveling across town and damage to vehicles than from inundation or damages to their homes or neighborhoods. Binationally, women respondents felt less prepared for future floods than men. On both sides of the border, community members and local experts agreed that Ambos Nogales lacks adequate preparation for future floods. To increase preparedness, they recommended flood risk education and awareness campaigns, implementation of green infrastructure, additional stormwater infrastructure (such as drainage systems), enhanced flood early warning systems, and reduction of flood flows through regulations to reduce the expansion of hard surfaces. This study contributes systematic collection of information about flood risk perceptions across an international border, including novel data regarding risks related to climate change and gender-based assessments of flood risk. Our finding of commonalities across both border communities, in perceptions of flood risk and in the types of risk reduction solutions recommended by community members, provides clear directions for flood risk education, outreach, and preparedness, as well as measures to enhance cross-border cooperation.
