Topography of inland deltas: Observations, modeling, and experiments
No full textThe topography of inland deltas is influenced by the water-sediment balance in distributary channels and local evaporation and seepage rates. In this letter a reduced complexity model is applied to simulate inland delta formation, and results are compared with the Okavango Delta, Botswana and with a laboratory experiment. We show that water loss in inland deltas produces fundamentally different dynamics of water and sediment transport than coastal deltas, especially deposition associated with expansion-contraction dynamics at the channel head. These dynamics lead to a systematic decrease in the mean topographic slope of the inland delta with distance from the apex following a power law with exponent alpha = -0.69 +/- 0.02 where the data for both simulation and experiment can be collapsed onto a single curve. In coastal deltas, on the contrary, the slope increases toward the end of the deposition zone.This work was funded by the Swiss National Foundation grant NF20021-116050/1. The author D.

The process of co-designing a model of social prescribing: An Australian case study.
No full textINTRODUCTION: Social needs such as housing, employment, food, income and social isolation are having a significant impact on individuals, families and communities. Individuals are increasingly presenting to health settings with social needs, which are ill-equipped to address nonmedical needs. Social prescribing is a systematic approach connecting the health, social and community sectors to better address social needs and improve health and wellbeing. Social prescribing interventions are being implemented world-wide. With variability in health and social care systems internationally, it is important that social prescribing interventions are co-designed with key stakeholders to ensure they can be implemented and sustained within local systems. METHODS: This Australian case study provides a detailed description of the process undertaken to co-design a social prescribing service model in a regional area. Four co-design workshops were undertaken, two with health and social care professionals and two with community members. The project followed an iterative process of resourcing, planning, recruiting, sensitising, facilitation, reflection and building for change across the workshops. RESULTS: Through this process, key stakeholders were able to successfully co-design a social prescribing model of care for the region. CONCLUSION: By demonstrating the process and materials used in our project, we aim to open the 'black box' of co-design for social prescribing and provide ideas and resources for others to adapt and utilise. PATIENT OR PUBLIC CONTRIBUTION: The project was designed and undertaken by a steering committee comprising university-based researchers (authors C. O. and S. B.), local government (author D. A.) and health, social and community services (authors B. G., M. W., J. O. and S. R.). Members of the steering committee participated in project design, participant recruitment, workshop facilitation, data analysis and interpretation
