Applied Solutions for Water Resource Challenges: Floods, Contamination and Upland Water Storage

poster abstractThe Center for Earth and Environmental Science, an IUPUI Signature Center, is working on a series of water resources problems and creating solutions. A series of collaborative projects are underway with the HUD, FEMA, the Office of Community and Rural Affairs, the United States Geological Survey, the Indiana State Department of Agriculture, and an international corporate partner in Berlin, KompetenzZentrum Wasser Berlin. Flood Erosion Hazard Program CEES, the USGS, and Polis are working with HUD and the Office of Community and Rural Affairs, though the Indiana Silver Jackets, to create tools for the State of Indiana to incorporate flood erosion hazard risk assessments into community planning. Flooding remains the most costly natural hazard in the US and Indiana. Flood losses continue to rise despite billions of dollars in mitigation. The causes are complex and related to land use, infrastructure design and climate change. Following the June 2008 floods in Indiana, 39 counties were listed as Federal disaster areas. In early 2005, 90% of Indiana counties were declared federal disaster areas after heavy rains fell on saturated soil. There have been seven major regional flooding events since the “Great flood of 1913”. The frequency of large floods appears to be increasing. Four of the eight major floods have occurred since 1982 and the last two occurred in 2005 and 2008. From 1998 through 2007, total insured flood losses in Indiana exceeded $39.8 million. While more restricted in area than the floods of 2008; record flooding occurred again throughout central and southern Indiana in early 2011 following heavy rains in February and March. Traditional flood protection usually consists of three components: flood control reservoirs, urban levees/floodwalls, and agricultural levees. These traditional flood protection methods are focused on one aspect of flooding – inundation. However, the largest single source of flood losses, both in terms of cost and number of affected persons, is damage to transportation infrastructure. Fluvial erosion is a principal cause of this damage. This significant flood-related natural hazard – the “fluvial erosion hazard” (FEH) – is not a specific component of State and local mitigation programs. This project aims to generate the tools for inclusion of FEH into statewide and local community planning. Aquisafe II - Performance Analysis of Selected Mitigation Systems Used to Attenuate Non-Point Source Agricultural Pollution Aquisafe is an international research collaboration with Veolia Environment based in Paris, their corporate partner in Berlin (KompetenzZentrum Wasser – Berlin Center of Competence for Water), the German Federal Environmental Agency, German university partners, and French quasi-governmental agencies in Brittany, France. The project goals are to create new mitigation systems to capture and treat polluted agricultural water running off farm fields prior to flowing into area streams, especially those used for drinking water supplies. The contaminants of specific concern are nutrients (nitrogen and phosphorus) and pesticides (atrazine – a corn-herbicide with potential endocrine disrupting effects). We are testing 2-stage, constructed wetlands in Indianapolis, Indiana and Brittany, France that have been designed to intercept and convert contaminants to harmless compounds. Site designs are guided by laboratory technical scale experiments conducted in Berlin that identified the hydrologic retention times and suitable sources of organic carbon necessary for mitigating contaminants. Construction of the experimental systems will begin in April in the Eagle Creek Watershed in cooperation with a private farmer with initial results expected this summer

It builds on progress made in California Water Plan Update 2013; reaffirms State government’s unique role and commitment to sustainable, equitable, long-term water resource management; and introduces implementation tools to inform sound decision-making.https://digitalcommons.csumb.edu/hornbeck_usa_3_d/1115/thumbnail.jp

Irrigation and water resources in Latin America and the Caribbean: challenges and strategies

Latin America and the Caribbean are relatively well endowed with water resources. However, population growth and rapid urbanization are putting considerable pressure on water available for irrigation. Local and regional water scarcity problems are exacerbated by severe water quality problems; and wastewater is frequently used for irrigation. Moreover, prospects for new investments into irrigation development appear limited. This paper examines the factors underlying irrigation development in Latin America and the Caribbean, reviews the water supply situation, and describes trends in water demand and irrigated agriculture. The overall water management in the region is assessed, and recent trends in investments in the water sector, with a focus on large-scale irrigation systems, are analyzed. The paper concludes that in this context of accelerating demand and declining irrigation investments, new water development is not the primary solution to water resource challenges in the region. Much greater attention is needed on water policy and management reform to improve the efficiency and equity of irrigation and water supply systems.Water resources development Caribbean Area., Water-supply., Water use Management., Irrigation farming.,

Water Use Trends in the United States

Since 1950, the United States Geological Survey (USGS) has collected and released data on national water use every five years for each state, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. In November 2014, the USGS released water-use estimates for 2010. These data are collected from a variety of sources, including from national data sets, state agencies, questionnaires, and local contacts (Maupin et al. 2014). They include estimates of withdrawals of freshwater and saline water from groundwater and surface-water sources and water use by sector. Using these data and historic data from several other sources, this paper reviews national water-use trends, going as far back as 1900 in some cases. For this analysis, we use the term "water use" to refer to the amount of water withdrawn from the ground or diverted from a surface-water source for use. Our analysis finds that we have made considerable progress in managing the nation's water, with total water use less than it was in 1970, despite continued population and economic growth. Indeed, every sector, from agriculture to thermoelectric power generation, shows reductions in water use. National water use, however, remains high, and many freshwater systems are under stress from overuse. Moreover, climate change will exacerbate existing water resource challenges, affecting the supply, demand, and quality of the nation's water resources. In order to address these challenges, we must continue and even expand efforts to improve water-use efficiency in our homes, businesses, industries, and on our nation's farms

Application of Treatment Technology, Grey Water Waste Management and Rainwater Harvesting in the Environment of RW 11 Bandung City

This project addresses critical water resource challenges in urban areas, particularly in Bandung City, Indonesia, where increased demand due to a high population exacerbates groundwater depletion and clean water scarcity. The area of focus is RW 11, Kel. Sukaluyu, Cibeunying Kaler District, which suffers notably from droughts and a significant lack of clean water. The proposed solution involves the development of portable, home-scale technology for the treatment and reuse of greywater and rainwater. This innovative approach is designed to decrease reliance on groundwater and provide a reliable water source during dry seasons. Additionally, the project aims to educate the local community in RW 11 about the importance of maintaining the groundwater cycle. The ultimate goal is to alleviate water scarcity in the area, especially during drought periods, thereby contributing to sustainable water resource management in urban contexts

Multiple metrics for quantifying the intensity of water consumption of energy production

Discussion of the environmental implications of worldwide energy demand is currently dominated by the effects of carbon dioxide (CO[subscript 2]) emissions on global climate. At the regional scale, however, water resource challenges associated with energy systems are a growing concern. This paper, based on an inventory of national energy portfolios, posits an indicator-based framework for characterizing regional energy portfolios' relative water intensity. These calculations extend upon a previous paper that established a method for calculating the national water consumption of energy production (WCEP) at the global level. Intensity indicators are based on normalizing the WCEP results with a set of additional indicators (including population, gross domestic product, total energy production, and regional water availability). The results show great variability in water consumption across nations, as well as across the various water intensity measures that were applied. Therefore, it is best to apply this full suite of indicators to each country to develop an integrated understanding of the intensity of water use for energy across countries
