Proposal – Senior Design Group 142
Students: Wei Yu (Electrical Engineering) Ayodele Asaolu (Electrical Engineering) Muhammad U. Khokhar (Electrical Engineering) Advisor: Quing Zhu (ECE Department) Sponser: U.S. Geological Survey – Office of Groundwater
Scientific agency of the US government. Study of landscape, natural resources, and the natural hazards that threaten it. Divided into four major science disciplines, concerning biology, geography, geology, and hydrology. Branch of Geophysics – Ground Water Management
Providing technical support and guidance Applied Research Improve monitoring methods Monitor hydrologic processes Borehole-radar methods for ground-water investigations Technology Transfer Improve monitoring methods Testing of newly developed geophysical technology
Phase 1: Developing an inexpensive data acquisition-storage device which incorporates the use of a geophone. Phase 2: Developing a sustainable energy power source for the device. Phase 3: Create a means of accessing the device via satellite or mobile device.
