anthropogenic alterations have affected urban hydrology in india and have generated a wide range of hydrological problems. such alterations include increase in directly-connected impervious cover thus reducing natural groundwater recharge. in the past urban runoff was largely viewed as a nuisance, but within the new paradigm of sustainability, this water is recognized as a potential resource. t...

urban quality of life represents more than the private “living standards” and refers to all the elements of the conditions in which people live, that is, all their needs and requirements. in economic literature, urban quality of life is usually assessed through the standard revealed-preference approach, which defines a qol index as the monetary value of urban amenities. this paper proposes an i...

r a 200 .004 esent ad Geoscien ox X, A +1 512 4 kherjee@ Summary Samples of deep groundwater, river water and rainwater were collected for dO and dH analyses from an area of 22,000 km in the arsenic-affected districts of West Bengal, India, in order to examine groundwater recharge. A plot of dO versus dH of groundwater falls subparallel to the constructed local meteoric water line (dH = 7.2 dO ...

Groundwater, a special hydrological variable and freshwater resource is completely inter-reliant with hydro-metorological, topographic, land use and hydro-geological components of hydrologic cycle. Trend of hydrologic componentsfor future prediction is attempted to confer in this study using Man-Kendall test, linear regression and geometric progression analysis on recorded data collected from r...

A regional regression model was developed to estimate the spatial distribution of ground water recharge in subhumid regions. The regional regression recharge (RRR) model was based on a regression of basin-wide estimates of recharge from surface water drainage basins, precipitation, growing degree days (GDD), and average basin specific yield (SY). Decadal average recharge, precipitation, and GDD...

Groundwater recharge from rainstorms can be vital for regional water resources. With the expansion of the need for more water in some specific regions under global climate change, groundwater is being pumped at a far greater rate than it can be naturally replenished. Considering that excess rainstorms could be utilized for groundwater recharge to lessen the declining tendency of regional ground...

The linear mathematical model for springflow suggested by Bear (1979) can simulate springflow for an initial instantaneous recharge. A springflow model has been developed, using the Bear model and Duhamel's approach, which can simulate springflow for time variant recharge. The suggested model can also be used to compute the time variant recharge to the springflow domain from a given springflow ...

Hydrologic analyses are commonly based on a single conceptual model. Yet hydrologic environments are open and complex, rendering them prone to multiple interpretations and conceptualizations. Considering conceptual model uncertainty is a critical process for the assessment of hydrologic uncertainty. This study assesses recharge and geologic model uncertainty for the Climax Mine area of the Neva...
