Abstract. The impact of water policy on sustaining the Ogallala Aquifer is analyzed using a system-level theoretical approach integrating agricultural water and land use tendencies, changing climate, economic trends, and population dynamics. In so doing, we 1) model the current hyper-extractive coupled natural-human system (CNH), 2) forecast future outcomes of policy scenarios transitioning the current groundwater-based economic system toward more sustainable paths for the social, economic and natural components of the integrated system, and 3) communicate model projections to inform public policies for enhanced sustainability while minimizing the economic pain for the region's communities. The findings corroborate previous studies showing that conservation often leads initially to an expansion of irrigation activities. However, we also find that the expanded presence of irrigated acreage will reduce the impact of an increasingly dryer climate on the region's economy and create greater long-term stability in the farming sector along with increased employment and population in the region. The primary negative aspect of more extensive conservation policies are on the net present value of farmers' current investments in their operations. This study reinforces the salience of interdisciplinary linked CNH models to provide policy prescriptions to untangle and address significant environmental policy issues.

Abstract. The impact of water policy on conserving the Ogallala Aquifer in Groundwater Management District 3 (GMD3) in southwestern Kansas is analyzed using a system-level theoretical approach integrating agricultural water and land use patterns, changing climate, economic trends, and population dynamics. In so doing, we (1) model the current hyper-extractive coupled natural-human (CNH) system, (2) forecast outcomes of policy scenarios transitioning the current groundwater-based economic system toward more sustainable paths for the social, economic, and natural components of the integrated system, and (3) develop public policy options for enhanced conservation while minimizing the economic costs for the region's communities. The findings corroborate previous studies showing that conservation often leads initially to an expansion of irrigation activities. However, we also find that the expanded presence of irrigated acreage reduces the impact of an increasingly drier climate on the region's economy and creates greater long-term stability in the farming sector along with increased employment and population in the region. On the negative side, conservation lowers the net present value of farmers' current investments and there is not a policy scenario that achieves a truly sustainable solution as defined by Peter H. Gleick. This study reinforces the salience of interdisciplinary linked CNH models to provide policy prescriptions to untangle and address significant environmental policy issues.

“…When these issues are considered in sum, the increasing observational capability of satellites will not have an equivalent impact on increasing societal applications until creative and cost-effective solutions are devised to improve the utility of satellite data for decision makers (Hossain, 2015, Bulatewicz, 2014). …”

A Scalable Open-source Web-analytic Framework to Improve Satellite -based Operational Water Management in Developing Countries Nishan Kumar BiswasChair of the Supervisory Committee: Associate Professor Faisal Hossain Department of Civil and Environmental Engineering Satellite based observations are becoming more widespread for operational and decision making activities in water resources due to their near real-time availability as well as minimization of difficulties related to ground based hydrological measurements. In this study, two crucial hurdles to advance real-world operationalization of satellite datasets are addressed. First, a simple, easy-to-access, easy-to-build, robust and consistent open-source web portal is developed connecting complex models to facilitate satellite based observations by developing nations.Second, to enhance the predictability skill of satellite-based estimations, an innovative and dynamic web analytics-based correction system is developed to reduce the uncertainty related to indirect method of measurement by the satellites. The correction system comprised of precipitation correction and streamflow correction. In precipitation correction, web crawled precipitation from different sites of government agencies of South Asia region are used to estimate bias in satellite based precipitation. This dynamically bias adjusted precipitation is then used to simulate hydrological models to obtain streamflow. Simulated streamflow is corrected using discharge climatology and gauged discharge observations. These corrected datasets are finally shared through South Asian Surface Water Modelling System (SASWMS) web portal. On an average, these dynamic correction techniques reduced RMSE in streamflow by 80-90%. The take-home message is that with the growth of open-source tools, it is now possible for any resourceconstrained water management agency to build robust and cost-effective operational web portals based on satellite data and non-proprietary software. With dynamic correction features that can also be built from open-source tools, the well-known limitations of satellite-based operationalization can be overcome for water management agencies of developing countries.v
