Simulating irrigation systems by accounting for various water loss rates is necessary while modeling the hydrology of cultivated canal-irrigated watersheds. The existing approaches to modeling canal irrigation use situation-specific optimization procedures. In addition, they are focused on a water management perspective rather than a hydrologic perspective. In this study, an approach is develop...

The U.S. Environmental Protection Agency (USEPA) and the U.S. Department of Agriculture (USDA) are promoting point/nonpoint trading as a way of reducing the costs of meeting water quality goals. Farms can create offsets by implementing management practices such as conservation tillage, nutrient management and buffer strips. To be eligible to sell offsets or credits, farmers must first comply wi...

If the components of security assurance are broadly defined in terms of capabilities (IT hardware and software products) and operations (systems management and process), this approach endeavors to quantify the operations component. That is, by quantifying the probability of secure operating practices, the risk evaluation of “cyber damage” will be more accurate. An oft-quoted mantra of security ...

The Conservation Effects Assessment Project was established to quantify water quality benefits of conservation practices supported by the U.S. Department of Agriculture (USDA). In 2004, watershed assessment studies were begun in fourteen agricultural watersheds with varying cropping systems, landscapes, climate, and water quality concerns. This paper reviews USDA Agricultural Research Service '...

Virtual projects are common with global competition, market development, and not least the financial crisis forcing organizations to reduce their costs drastically. Organizations therefore have to place high importance on ways to carry out virtual projects and consider appropriate practices for performing these projects. This paper compares best practices with practiced practices for virtual pr...

This paper examines the problem of insufficient and often inaccurate water management boundary data in California. Due to fragmented water management in California, no central government agency is responsible for coordinating water data collection, authorship, and dissemination and maintenance. Despite statewide and county scale efforts to build spatial data infrastructures that include water d...

Index words: Watershed studies Best Management Practices Restoration Remediation Aquatic systems Studies that evaluate the linkages between watershed improvement through Best Management Practices (BMPs) and downstream outcomes are few. Water quality of coastal waters is often impacted by soil and nutrient loss fromwatersheds in agriculture. Mitigation of these impacts is of concern in the Great...

As the number of inhabitants in Sub-Saharan Africa (SSA) increases, demand for animal-source proteins outstrips current supply. Aquaculture is promoted to sustain livelihood and improved food security. However, production SSA still low at less than 1% total global production. Poor water quality cited be one factors limiting growth aquaculture sector attributed limited familiarity with standard ...

Intensive agricultural practices in farming systems in eastern Australia have been identified as a contributor to the poor runoff water quality entering the Great Barrier Reef (GBR). A field investigation was carried out to measure the off-farm water quality and productivity in a coastal farming system in northeastern Australia. Two vegetable crops (capsicum and zucchini) were grown in summer 2...
