We optimize groundwater management in the presence of marine consequences of submarine groundwater discharge (SGD). Concern for marine biota increases the optimal steady-state head level of the aquifer. The model is discussed in general terms for any coastal groundwater resource where SGD has a positive impact on valuable near-shore resources. Our application focuses of the Kona Coast of Hawai’...

We examine the practical problem of a mobile autonomous robot performing a long-duration survey task, during which it must recharge its batteries periodically. We present a scalable, online, heuristic method that allows the robot to recharge efficiently, thus maximizing its rate of work. The method is a direct application of the rate-maximizing foraging model, which seeks to explain the behavio...

The majority of India’s rural drinking water supply is sourced from groundwater, which also plays a critical role in irrigated agriculture, supporting the livelihoods millions users. However, recent high abstractions are threatening sustainable use and action needed to ensure continued supply. Increased managed aquifer recharge (MAR) using > 200,000 existing tanks (artificially created surface ...

An Essential Hormone Testosterone, estrogen, cortisol, DHEA, and pregnenolone are members of a family of natural hormones that are essential for human survival. All of these hormones contain four carbon-ring structures attached to each other, and appear very similar.1Small differences in structure, however, produce dramatic changes in function. Testosterone, the “male” hormone, is only slightly...

Abstract Land-use changes often have significant impact on the water cycle, including changing groundwater/surface-water interactions, modifying groundwater recharge zones, and increasing risk of contamination. Surface runoff in particular is significantly impacted by land cover. As surface can act as a carrier for contaminants found at surface, it important to characterize dynamics anthropogen...

Present study was carried out to delineate groundwater prospect zones and identification of artificial recharge sites using Indian remote sensing satellite (IRS) 1D PAN geocoded data on 1:12,500 scale and Survey of India (SOI) topographical sheets. The information based on lithology, geomorphology, soil, land-use/ land-cover, structures/lineament, slope, drainage and hydrology were generated an...
