The hydrogeochemistry of pond and rice field recharge : implications for the arsenic contaminated aquifers in Bangladesh
(Massachusetts Institute of Technology, 2010)The shallow aquifers in Bangladesh, which provide drinking water for millions and irrigation water for innumerable rice fields, are severely contaminated with geogenic arsenic. Water mass balance calculations show that ... -
The hydrographic city : mapping Mexico City's urban form in relation to its aquatic condition, 1521-1700
(Massachusetts Institute of Technology, 2013)Mexico City is a special case in urban history because the measures taken by the Aztec and Spanish to avoid inundations have fundamentally changed the city's character. In 1521, it was an island-city; in 1629, it lay near ... -
Hydrographic structure of overflow water passing through the Denmark Strait
(Massachusetts Institute of Technology, 2015)Denmark Strait Overflow Water (DSOW) constitutes the densest portion of North Atlantic Deep Water, which feeds the lower limb of the Atlantic Meridional Overturning Circulation (AMOC). As such, it is critical to understand ... -
Hydrography and circulation about Nantucket Shoals
(Massachusetts Institute of Technology, 1979) -
Hydrologic and bacteria modeling of the upper Charles River watershed using HSPF
(Massachusetts Institute of Technology, 1997) -
Hydrologic and chemical analysis of salt ponds on St. John, U.S. Virgin Islands
(Massachusetts Institute of Technology, 2003)In order to assess the impact of human development on salt ponds, this study investigated the relationships between the chemistry of salt ponds and the hydrology of the surrounding area. Aspects of pond health such as ... -
Hydrologic and hydraulic assessment of artificial recharge in the Sparta Aquifer of Union County, Arkansas
(Massachusetts Institute of Technology, 2013)Groundwater pumping from the Sparta aquifer in Union County, Arkansas, has long exceeded natural recharge, threatening the regional water supply. An alternative water-supply project, completed in 2004, now provides treated ... -
Hydrologic and water quality modeling with HSPF : utilization of data from a novel field data collection system and historical archives
(Massachusetts Institute of Technology, 2002)Catchment-scale hydrology and water quality studies are empowered by current mobile computing, wireless, and Internet technologies to new levels of technical assessment capability. These technical developments motivate an ... -
A hydrologic calibration of the SWAT model in Kranji Catchment, Singapore
(Massachusetts Institute of Technology, 2012)The Public Utilities Board (PUB) of Singapore wishes to expand recreational activities in Singapore's surface waters through the Active, Beautiful, and Clean Waters Program (ABC Waters). One area of concern with ABC Waters ... -
Hydrologic data assimilation of multi-resolution microwave radiometer and radar measurements using ensemble smoothing
(Massachusetts Institute of Technology, 2006)Previously, the ensemble Kalman filter (EnKF) has been used to estimate soil moisture and related fluxes by merging noisy low frequency microwave observations with forecasts from a conventional though uncertain land surface ... -
Hydrologic modeling of the Williams River with tRIBS : development and testing of a novel user interface for the TIN-based hydrologic model
(Massachusetts Institute of Technology, 2002) -
Hydrologic modeling using triangulated irregular networks : terrain representation, flood forecasting and catchment response
(Massachusetts Institute of Technology, 2003)Numerical models are modern tools for capturing the spatial and temporal variability in the land-surface hydrologic response to rainfall and understanding the physical relations between internal watershed processes and ... -
Hydrologic modelling of New England River basins using radar rainfall data
(Massachusetts Institute of Technology, 1988) -
Hydrologic-economic modeling of irrigated agriculture in the Lower Murrumbidgee Catchment : investigations into sustainability
(Massachusetts Institute of Technology, 2000)Increasing water scarcity and growing demand for food have made better management of land and water resources essential to maintaining the sustainability of irrigated agriculture. Policies designed to improve environmental ... -
Hydrological and biogeochemical cycling along the Greenland ice sheet margin
(Massachusetts Institute of Technology, 2012)Global warming has led to a significant increase in Greenland ice sheet (GrIS) melt and runoff since 1990, resulting in escalated export of fresh water and associated sediment to the surrounding North Atlantic and Arctic ... -
Hydrological disasters : designing to shelter in place
(Massachusetts Institute of Technology, 2021)The focus of this thesis is hydrological disasters and the question it attempts to answer is: how can we design and implement housing structures along U.S. coastlines that fully withstand hydrological disasters? Priority ... -
Hydrological urbanism in China's Pearl River Delta : how water landscape shapes the urban form in a changing climate
(Massachusetts Institute of Technology, 2015)When standing among urban villages, residential towers and warehouses in an urbanizing city in the Pearl River delta (PRD), it is hard to imagine that just forty years ago this area was filled with streams, ponds and rice ... -
The hydrology of malaria : field observations and mechanistic modeling of the malaria transmission response to environmental climatic variability
(Massachusetts Institute of Technology, 2009)A coupled HYDrology, Entomology and MAlaria Transmission Simulator (HYDREMATS) has been developed. The model simulates the hydrological and climatological determinants of malaria transmission mechanistically and at high ... -
